STEP ONE - REGISTERING YOUR BEACON  
1.  
Why is registration important?  
As the owner of this 406 MHz beacon, it is mandatory that you register it  
with the EPIRB national authority of your country: It is the law. Please  
note that all 406 MHz beacons are required to have their registration updated  
every two years by the owner.  
Your unique ID code  
programmed inside each EPIRB is  
YOUR RESCUE WILL  
BE DELAYED IF YOUR  
BEACON ISN’T PROPERLY  
REGISTERED!  
transmitted to Search and Rescue  
(SAR). SAR forces use this code to pull  
up your registration to find out valuable  
information about who needs help.  
HOW REGISTRATION WORKS:  
All 406 MHz beacons transmit a Unique Identifier Number (UIN) when  
activated. This UIN is programmed into the beacon based on the country in  
which the beacon is registered, thus authorities are able to determine which  
country’s database will have your registration information. SAR forces will  
have information as to who you are as the owner of the beacon, the name  
and type of vessel that you have, your homeport, and who to contact that  
might know of your current situation - but only if your beacon has been  
properly registered. Valuable search and rescue resources are wasted every  
year responding to false alarms, and registering your beacon helps to resolve  
false alarms quickly.

2.  
What country should I register in?  
Register your beacon with the EPIRB national authority of the country for  
which the beacon was programmed, typically the country where purchased,  
regardless of where you do your boating.  
The beacon must be reprogrammed if you, as the owner, move or the vessel  
sails under the flag of a different country than the one for which the beacon  
was previously programmed. To verify the country for which a beacon is  
programmed, see the label with the UIN (Unique Identification Number) on  
the back of the unit. Units that do not have a country specified on the UIN  
label are programmed for the United States.  
3.  
How do I register?  
Registration in the United States  
The national authority that accepts registrations in the United States is the  
National Oceanic and Atmospheric Administration (NOAA).  
Here are three ways to register:  
1. The fastest and easiest way to register is online at  
2. Faxing a registration is also acceptable. Fax the registration form to the fax  
number on the top of the registration form.  
NOTE: Do not confuse the registration form with the ACR Electronics  
warranty card.  
3. If online or fax registration is not available, mail the registration form with the  
pre-addressed, postage paid envelope to:  
NOAA SARSAT Beacon Registration  
NSOF, E/SP3  
4231 Suitland Road  
Suitland, MD 20746  
All registration forms will be entered in the 406 MHz beacon registration  
database within 48 hours of receipt. The information you provide on the  
registration form is used for rescue purposes only.  
A confirmation letter, a copy of the actual registration and a proof-of-  
registration decal will be mailed to you within two weeks. When you receive  
these documents, please check the information carefully with the  
existing label on the unit, and then affix the decal to your beacon in the  
area marked “BEACON DECAL HERE.” If you do not receive confirmation  
back from NOAA in the expected timeframe, call toll free (888) 212-7283 for  
assistance.

Registration outside of the United States  
In countries other than the United States, 406 MHz beacons are registered  
with that country’s national authority at the time of purchase. The sales agent  
should have assisted you in filling out the forms and sending them to the  
country’s national authority. Alternatively, many countries allow online  
registration in the International 406 MHz Beacon Registration Database  
To verify that the unit is properly programmed for your country, view the UIN  
label on the back of the unit. In the event that the beacon is not programmed  
for your country, the sales agent (if properly equipped) can reprogram the unit  
for the correct country.  
4.  
Do I need a radio license?  
In the United States, you may or may not need to obtain or update a radio  
station license. Check the FCC’s website at  
call toll-free (888) 225-5322 (CALLFCC) for the latest information.  
Outside of the United States, contact your local authority for the  
requirements.

STEP TWO - HOW THE BEACON WORKS  
1.  
How your beacon brings help  
406 MHz beacons are a type of portable emergency equipment that transmits  
a distress signal to search and rescue (SAR) organizations. The purpose of  
these beacons is to aid SAR teams in tracking and locating ships or  
individuals in jeopardy as rapidly as possible.  
The 406 MHz frequency is a worldwide dedicated emergency frequency that  
is detected by a special system of satellites called the Cospas-Sarsat system.  
This satellite system was established by, and continues to be supported by,  
its primary benefactors - the USA, Russia, Canada and France. The Cospas-  
Sarsat system has saved over 23,500 lives - and counting - since its  
inception. See Appendix G or the Cospas-Sarsat website for more  
information about the system at www.cospas-sarsat.org.  
When a 406 MHz beacon is activated, the digital distress message is sent to  
Cospas-Sarsat satellites and, in turn, the distress message is relayed to SAR.  
The distress message contains important information about the beacon and  
its owner. Additional information about the beacon is accessed by SAR from  
the beacon registration database. At the same time the 406 MHz signal is  
activated, a 121.5 MHz signal is turned on. The 121.5 MHz signal is used by  
SAR to home in on the beacon as they approach it.  
The 406 MHz signal is detected by multiple satellites and from that  
information the location of the beacon can be calculated. This data alone is  
sufficient for SAR to find persons or ships in distress in a reasonable  
timeframe. However, as a further enhancement, some beacons have a GPS  
engine onboard. This feature allows the beacon to acquire current location  
coordinates from an internal GPS receiver or download coordinates from an  
external GPS receiver. The coordinates are added to the ID of the unit, which  
is transmitted with the 406 signal. This enables the SAR authorities to locate  
the beacon to an accuracy of 110 yards (100 m).

3.  
Digital Display  
The digital display in the beacon is used as a secondary visual aid,  
supporting the green/red LED and the audio tone, which indicate the status of  
the beacon during testing and during emergency operation.  
The messages on the digital display typically appear as one or two words at a  
time, until the entire message has been displayed.  
When the beacon is activated, the display will show the message EPIRB ON.  
The beacon will begin to send 406 MHz emergency signal bursts, at which  
time the display provides other messages including 406 SENT, 121.5 ON and  
GPS coordinates, provided the data was acquired. If GPS data has not been  
successfully downloaded into the beacon, the digital display will give you tips  
like “GIVE CLEAR VIEW TO SKY.”  
GPS  
In Self-Test, the display illustrates the test result of each step with “√”  
indicating a pass and “X” indicating a failure. There are a total of five tests,  
plus a battery check. If all tests pass, SELF-TEST PASS will be displayed at  
the end of the Self-Test mode. This will be followed by the GPS coordinates  
horizontally scrolling through the display, provided the beacon has  
successfully downloaded an external GPS location. See Appendixes B  
through E for details about display messages.  
EPIRB

Language translations of the digital display messages are available from your  
local Battery Replacement Center (BRC). The messages can be converted to  
French, Spanish, German and Italian. See Appendix F for a list of messages  
by language.

Activating your beacon  
WARNING: This transmitter is authorized for use only during  
situations of grave and imminent danger. Deliberate misuse may incur a  
severe penalty.  
Overview  
Category I beacons are designed to be automatically deployed and activated  
in the event of a sinking vessel. The beacon may also be hand held on the  
deck of vessels, or floated in water and attached to a raft or life vest with the  
lanyard provided.  
Category II beacons are designed to be manually deployed from the bracket.  
Two conditions must be met for a Category II beacon to automatically  
activate:  
// It must be out of its bracket  
// It must be wet  
NOTE: Either condition by itself will not automatically activate the beacon.  
Category I and II beacons can always be manually activated in or out of their  
bracket.  
The beacon and bracket are designed to allow the user to perform periodic  
testing while the beacon is in its bracket.

11  
Category I beacons-Automatic deployment and activation  
If the vessel sinks, the HydroFix™ HRU frees the beacon from the bracket,  
allowing it to float to the surface. Built-in sensors detect that the beacon is no  
longer in its bracket and when continuity is created by water between two of  
the top cap screws, an activation circuit is completed.  
NOTE: Transmission of the 121.5 MHz and 406 MHz signals will not occur  
until 100 seconds after activation.

12  
Category I and II Beacons-Manual deployment and activation  
Both Category I and II beacons can be manually deployed by removing the  
beacon from the bracket.  
Once removed, the beacon can be activated by placing it in water OR by  
lifting the Activation Switch to a vertical position, sliding it toward the antenna  
and pushing down to the opposite side of the beacon. Activating the beacon  
in this manner breaks off the Activation Witness Tab and allows the switch to  
properly seat, showing the “ ▌ “ symbol (ON).  
A Category I or II beacon MANUALLY activates with the following sequence:  
1.) Remove the beacon from its bracket  
2.) Activation method one: Place beacon in water  
3.) Activation method two:  
// Lift the switch to a vertical position  
// Slide the switch toward the antenna  
// Push the switch down to the opposite side of the beacon (see  
illustration below)  
Category I and II Beacons-Manual Activation Without Deployment  
The beacon can be manually activated while still in its bracket by placing the  
Activation Switch in the ON position. Activation by this method overrides all  
sensors and turns the beacon “ON.”  
Witness tab will break  
once placed in the “ON”  
position  
Push the main switch up  
90 degrees, slide toward  
antenna and all the way  
down to activate.

TIPS FOR OPTIMUM DEPLOYMENT OF AN ACTIVATED BEACON:  
When activating and deploying your beacon in an emergency, DO  
NOT:  
// Hold or clutch the beacon or antenna  
// Operate the beacon while hand held, if at all possible  
// Turn the beacon off for any reason, including to save power  
// Activate the beacon if you have any other means of self rescue  
// Operate the beacon inside a life raft or under any other canopy or  
cover  
// Tether the beacon to the bracket or vessel  
When activating and deploying your beacon in an emergency, DO:  
// Follow the steps to activate the beacon as described on the beacon or  
in this manual  
// Give clear view to the sky for best GPS performance  
// Take the EPIRB with you if abandoning ship, provided there is time to  
get it  
// Tether beacon, using the lanyard, to the life raft and let the beacon float  
(if in a life raft)  
// Keep EPIRB upright for best signal transmission, either by floating it,  
resting it or holding it in this position  
// Manually activate the beacon if it has not been automatically activated  
5.  
Turning off the beacon  
If your beacon was manually activated and you wish to deactivate, return the  
thumb switch to the “OFF” position. If automatically activated and you wish to  
deactivate, remove the beacon from the water and dry the unit or place the  
beacon back into the release bracket. The beacon normally takes up to 12  
seconds to deactivate.  
If deactivation should fail, remove the four screws holding the unit together  
and unplug the battery to disable the unit. Return the beacon to ACR  
Electronics for service.  
6.  
False alarms  
To prevent false alarms, it is important to be aware of how your beacon can  
be activated. An ACR 406 MHz EPIRB can be activated by two different  
methods. Whether you have a Category I or Category II, these methods are  
the same.  
// When the beacon is out of its bracket and wet, the unit will start  
transmitting  
// When the switch is moved to the “ON” position, in or out of the  
bracket, the unit will start transmitting  
Y1-03-0233DRowenvl.oaDd from Www.Somanuals.com. All Manuals Search And Download.  
14  
Precautions to prevent false alarms  
// Do not mount or transport the beacon within 4.6ft/1.4m of a magnetic  
source.  
// Do not store the beacon outside of its bracket if it can get wet.  
// Do not mount the EPIRB backwards in its bracket (lanyard roll must  
face in).  
// Do not clean the beacon with a water hose and brush while out of its  
bracket.  
Reporting  
Should there be, for any reason, an inadvertent activation or false alarm, it  
must be reported to the nearest search and rescue authorities. The  
information that should be reported includes:  
// The EPIRB 15-digit Unique Identifier Number (UIN)  
// Time and date  
// Duration and cause of activation  
// Location of beacon at the time of activation  
To report false alarms in the United States, contact any of the following:

STEP THREE - INSTALLING THE BEACON  
1.  
Marking battery and Hydrostatic Release Unit expiration dates  
NOTE: It is the beacon owner’s responsibility to record the expiration dates  
for both the beacon battery and the HydroFix™ hydrostatic release unit. This  
information must appear on the product itself.  
The left side of the battery housing indicates the battery expiry date. Space is  
provided for the beacon owner to mark the date the beacon was placed into  
service. The beacon should be serviced 5 years from the installation date but  
no later than the battery expiry date.  
The ACR HydroFix™ HRU has an expiration date of 2 years from the date  
of installation or 4 years from the date manufactured, whichever comes  
first. Upon installing your beacon or new HRU, permanently scratch the  
new expiration date on the HRU date calendar as seen below.  
Date of Installation Example:  
Date of installation of New HRU or First  
Installation of EPIRB including new  
HRU: August 1, 2009.  
This unit will need to be replaced in  
August of 2011. Scratch off “AUG 8”  
and “2011” on the HRU date calendar  
Date of Manufacture Example:  
On the bottom of the HRU a date of  
manufacture is pin stamped: 0808.  
This unit will need to be replaced in  
August 2012. Scratch off “AUG 8” and  
“2012” on the HRU date calendar  
2.  
Mounting location  
The selection of a mounting location will vary from vessel to vessel. Beacons  
should be protected from outside influences while being readily accessible at  
all times in the event of an emergency.  
The location selected must be sufficiently rigid to support the weight of the  
total installation.  
Hazards to avoid when selecting a mounting location:  
// Vibration  
// Exposure to the elements  
// Possibility of impact from hatches, gear, or personnel  
// Harmful vapors  
// Exhaust  
// Harsh chemicals  
// Locations that can be obscured by foreign articles on a temporary or  
permanent basis.

16  
CAUTION: Category I brackets must be mounted free from  
obstruction to allow the beacon to automatically float free from the vessel  
in case of sinking. The SeaShelter3can be mounted on a vertical  
surface with the beacon antenna pointing skyward or a horizontal surface  
with the beacon face up. Avoid mounting locations that subject the  
bracket to breaking waves. Avoid structures like dodgers or cabin tops  
that could trap the beacon upon deployment.  
CAUTION: Category II brackets must be mounted in a protected  
location that is easily accessible should it be necessary to abandon ship.  
The LowPro3™ can be mounted on a vertical surface with the beacon  
antenna pointing skyward or a horizontal surface with the beacon face  
up. Avoid mounting locations that subject the bracket to breaking waves.  
Avoid mounting locations that do not provide protection from harmful UV  
rays of the sun. The bracket must be mounted facing inboard to avoid  
being lost overboard due to impacts of breaking waves, personnel or  
loose gear.  
Visually inspect the area surrounding the mounting bracket installation site for  
hidden hazards or obstacles that may have been overlooked during the  
location selection. If there is any doubt as to the ready accessibility to the  
beacon at all times or if any condition may appear to be questionable,  
conduct a complete and thorough investigation before final approval of the  
installation.  
NOTE: When selecting the beacon bracket location, be sure to consider the  
requirement for four screw holes to secure the bracket, plus one hole for the  
NMEA cable for connection between an external GPS and the beacon, if  
connecting the beacon to an external GPS receiver.  
Y1-03-0233DRowenvl.oaDd from Www.Somanuals.com. All Manuals Search And Download.  
17  
CAUTION: Keep this beacon a safe distance away from all  
magnetic sources. Magnet safe distance is 4.6ft. or 1.4m, including  
the distance from stereo speakers.  
3.  
Category I bracket  
The SeaShelter3™ Category I bracket has five pre-drilled screw holes to use  
for securing the bracket to a flat surface. Remove the SeaShelter3™ lid by  
turning the spring loaded knob on the lid 1/4 turn counterclockwise and pull.  
The lid will lift away from the top of the base and disengage at the bottom of  
the base. The lid is tethered to the base to help prevent loss. Pull the beacon  
with steady pressure from the bracket. It is not necessary to remove the  
HydroFix™ Hydrostatic Release Unit (HRU) to mount the bracket using four  
of the holes. For extreme conditions a fifth hole is available when the  
HydroFix is removed and the ejector spring is deployed. The bracket can be  
held in place to mark the placement of the screw holes or you can use the  
mounting template provided. The use of #10 pan head stainless steel  
fasteners (minimum of ½” long) and ½” washers (not included) is  
recommended. Make sure that fasteners will not contact any wires or  
plumbing before drilling pilot holes.

18  
4.  
Category II bracket  
Category II brackets are designed to hold the beacon securely in place. The  
beacon must be manually deployed. The bracket can be mounted on a  
vertical flat surface with beacon antenna up or on a horizontal flat surface  
facing skyward. This location must be easily accessible in order to manually  
deploy the beacon or to perform the required maintenance and functionality  
tests. Typical locations include near the helm station or just inside the  
companionway door.  
The LowPro3™ Category II bracket has four pre-drilled screw holes to use for  
securing the bracket to a flat surface. Remove the beacon from the bracket.  
To do this while holding the assembly, lift the latch to release bracket  
pressure from the beacon. The beacon will slide up and out of the bracket.  
On either side of the bracket are release tabs. Simultaneously depress each  
tab to separate the bracket from the mounting block. The mounting block can  
be held in place to mark the placement of the screw holes or you can use the  
mounting template provided. The use of #8 pan head stainless steel  
fasteners and washers (not included) is recommended. Be sure to confirm  
that fasteners will not contact any wires or plumbing before drilling pilot holes.

5.  
Installing the optical interface to an external GPS receiver  
The beacon is fitted with an  
optical interface to connect with  
an external Global Positioning  
System (GPS) receiver that will  
determine the latitude and  
longitude of its position.  
The black lead wire with white  
stripes should be connected to  
the output of the external GPS  
receiver positive transmitter pin.  
The black wire should be  
connected to the negative pin.  
If you have a Category I beacon and bracket, the connector is at the end of  
the black lead wire plugs into the beacon via the bezel on the top of the  
beacon. See the location of the GPS interface in previous figures (“Anatomy  
of your beacon”, page 7 and “Top View”, page 8). It is important to seat the  
connector completely in the bezel for an operational connection.  
If you have a Category II beacon and bracket, your connector has two  
extensions on it that must be aligned with the two notches on the Category II  
beacon bezel. The connector is then gently inserted downward into place and  
turned 90° to lock the connector into the bezel.  
If the external GPS receiver is operational and the connection has been  
correctly made to the optical interface, the green LED in the optical interface  
will start flashing at activation.  
NOTE: The baud rate output for your GPS receiver NMEA 0183 should be  
4800 bps. If you are not sure if your receiver is NMEA 0183 compliant, check  
the interface settings listed in your GPS manual. To optimize your GPS  
interface feature, be sure that your GPS receiver is equipped with a NMEA  
0183 Version 1.5 or higher with GPGGA sentence enabled.  
Consult your GPS receiver manual for the maximum cable length acceptable  
for an external GPS connection to the beacon. Also see Appendix A for  
information regarding the use and testing of your GPS system in conjunction  
with the beacon.  
Using the optical interface is not necessary for the beacon to function  
properly; it will, however, enhance the beacon’s performance.

STEP FOUR - MAINTAINING THE BEACON  
1.  
Safety DOs and DON’Ts  
On a routine basis aboard ship, DO NOT:  
// Hold or carry the beacon by its antenna  
// Mount the beacon in its bracket close to large structures or magnetic  
areas  
// Tie the lanyard to the EPIRB bracket or any other structure  
// Obscure the beacon by placing objects in front of it  
On a routine basis aboard ship, DO:  
// Mount the beacon in its bracket in an obvious location, so that all can  
see it  
// Mount the beacon in its bracket with the rolled lanyard facing inward  
(facing the bracket)  
// Follow the recommended maintenance schedule  
// Perform a beacon Self-Test monthly  
// Follow up with beacon service if Self-Test fails  
2.  
Routine beacon maintenance  
At least every ninety days, the float free mounting bracket and beacon should  
be inspected for deterioration and/or residue buildup that may affect the  
function of the beacon or automatic release. Part of the visual check includes  
checking the antenna for tightness. Clean the beacon and the mounting  
bracket to remove any residue buildups. It is recommended that the beacon  
and mounting bracket be wiped with a damp cloth.  
Carefully inspect the beacon case for any visible cracks. Cracks may admit  
moisture, which could falsely activate the beacon or otherwise cause a  
malfunction. Any cracks observed should immediately be referred to ACR  
Service for evaluation. Call ACR Electronics Technical Service +1 (954) 981-  
3333.  
3.  
Battery replacement  
Battery replacement is due 5 years from date after the beacon placed into  
service, or by expiry date on the beacon whichever is first. During each  
inspection, check the time remaining until battery replacement is required.  
The battery must also be replaced if the beacon has been activated for any  
use other than the Self-Test.

Changing ownership or contact information  
As the owner of the beacon, it is your responsibility to advise the national  
authority of any change in the information on the registration form. If you are  
transferring the beacon to a new owner, you are required to inform the  
national authority. You can do this by using their online database or by letter,  
fax or telephone and informing the authority of the name and address of the  
new owner.  
The new owner of the beacon is required to provide the national authority  
with all of the information requested on the registration form. This obligation  
transfers to all subsequent owners. Registration forms for the United States  
are available from NOAA by calling (888) 212-7283 (212-SAVE) or by visiting  
the ACR website at www.acrelectronics.com. Outside of the United States,  
the new owner may contact his local authority for the necessary form(s).

Servicing the SeaShelter3™ and the HydroFix™ HRU  
The SeaShelter3™ Category I bracket has two main  
pieces, the lid and the base. To open the bracket, turn the  
spring loaded knob counterclockwise 1/4 of a turn and  
pull. The lid will lift away from the top of the base and  
disengage from the detent at the bottom of the base. The  
lid is tethered to the base to help prevent loss.  
Brackets are a key part of the overall beacon system.  
They hold a beacon ready for deployment while preventing  
false alarms. Category I brackets also require replacement  
of the Hydrostatic Release Unit every two years.  
NOTE: Whenever a beacon is returned for service, it  
must be accompanied by the bracket.

23  
To remove the expired HRU  
When opening the SeaShelter3™ lid, note that the beacon is installed with the  
lanyard face in. Pull the beacon with steady pressure from the bracket. Do  
not get beacon wet while out of bracket. The HRU has a keying feature that  
locks it to the bracket. If you view the HRU rod as the center of a clock, a  
properly installed HRU will rest at the 7 o’clock position, as shown in the  
picture above.  
WARNING: The HRU holds down an ejection spring. The spring must be  
held in place during the removal and installation of the HydroFix™ to prevent  
injury.  
Depress the top of the ejection spring. This will relieve pressure on the HRU  
and allow it to be rotated counterclockwise to the 5 o’clock position. The HRU  
is now free to be removed. Slowly relieve pressure from the ejection spring  
and allow it to deploy.  
WARNING: Discard the expired HRU. Failure to replace the entire  
assembly may cause the bracket to malfunction.  
WARNING: Be sure to use only ACR’s HydroFix™ HRU (ACR P/N 9490)  
in the SeaShelter3™. Use of unauthorized replacement parts will void your  
warranty and may cause the bracket to malfunction.  
Check the date of manufacture on the new HRU. Follow the instructions that  
accompany the HydroFix™ for marking the next expiry date and for selecting  
the correct rod adapter for the SeaShelter3.  
To install the new HRU  
Apply pressure to the ejection spring and hold it flat against the bracket. With  
your free hand place the new HRU into the key way in the 5 o’clock position  
and rotate clockwise to the 7 o’clock position. Slowly remove pressure from  
the ejection spring. The HRU should now be held in the 7 o’clock position  
with the pressure on the ejection spring.  
Reinstall the beacon with lanyard face in. Beacon should fit snugly in the  
bracket with the antenna captured by the bracket. Reinstall the lid by seating  
the bottom of the lid to the detent on the base. Close the upper portion of the  
lid so the HRU rod lines up with the spring loaded knob. With gentle pressure,  
hold the lid while you turn the lock counterclockwise until it stops, then  
clockwise until it stops. This should capture the HRU and snap the lid into a  
locked position. Confirm that the lid is attached to the bottom of the bracket  
and the HRU.  
CAUTION: Do not force the lid closed. If the lid does not close easily,  
check to see that the beacon is properly installed in the bracket and the  
HydroFix™ is properly seated.

9.  
Servicing the LowPro3™  
To remove a beacon from the Category II bracket, lift the latch and release  
the pressure from the beacon. The beacon will now be able to slide upwards  
out of the bracket.  
It is not anticipated that the LowPro3 will require servicing other than  
cleaning or, rarely, replacement.  
Brackets are a key part of the overall beacon system. They hold a beacon  
ready for deployment while preventing false alarms.  
NOTE: Whenever a beacon is returned for service, it must be accompanied  
by the bracket.  
10. Self-Testing the beacon  
The RLB-36 beacon may be self-tested as is warranted, up to a maximum of  
sixty times in the five-year life of the battery, or once per month for the life of  
the battery. Self-Tests can be performed randomly, however, ACR  
recommends that you perform the Self-Test on a once per month schedule.  
Do not exceed sixty (60) Self-Test cycles limit in the five-year life of the  
battery, to conserve the battery for emergency use.  
The functional Self-Test is initiated by momentarily  
lifting the Activation Switch to a vertical position and  
holding it in this position for at least one second and at  
most four seconds. A beep indicates the initiation of  
the Self-Test sequence. Self-Test will check battery  
capacity and perform five functional test sequences as  
described in the digital display Appendix.  
The last green LED and the message SELF-TEST PASS on the display  
indicate a successful test. If any of the individual tests fail during Self-Test,  
there will be two beeps and a red LED flash, with the name of the test that  
failed and an “X” on the display. Self-Test will discontinue at that point. See  
Appendix D for digital display information.  
NOTE: The “beeps” are a very high-pitched tone that some people may not  
be able to hear. When performing the Self-Test, you may follow the  
messages on the digital display or you may count the green LED flashes.

11. Extended GPS test  
The beacon may be tested for GPS functionality, however, this may only be  
done once in the five-year lifetime of the battery due to the significant drain  
on the battery. This test is not necessary at any time in the life of the beacon,  
but is made available in the event that the beacon owner wishes to verify  
internal GPS engine viability.  
An extended GPS test may be invoked by holding the switch in test position  
for 10 seconds after Self-Test completes. The display will show the message  
LONG GPS DATA TEST START while the internal GPS is acquiring  
coordinates data. Once the data is acquired, the display will post the  
message GPS TEST √ followed by the LAT/LON coordinates as a  
confirmation that the data was successfully acquired.  
See Appendix E for digital display information.

APPENDIX A - USING AND TESTING THE GPS SYSTEMS  
1.  
How the external GPS interface works  
The beacon is fitted with an optical interface to connect with an external  
Global Positioning System (GPS) receiver that will determine the latitude and  
longitude of its position. This data is transmitted to the emergency system.  
When the beacon is coupled to a working external GPS receiver, it  
immediately begins downloading data. Once valid position data has been  
obtained, the beacon will attempt to update the positional data every 20  
minutes. The GlobalFix™ iPRO will store the last valid positional data for up  
to 4 hours, if it becomes unable to obtain new updated data. It will update this  
data if and only if it receives new good positional data from the external GPS  
receiver.  
2.  
Using the external GPS interface  
Once a compatible, operating GPS receiver is connected to the GlobalFix™  
iPRO, the beacon will store coordinate data for incorporation into the  
emergency message. The coordinates are transmitted to the satellite when  
the beacon is activated in an emergency. Coordinate data provides a more  
accurate location to the Search and Rescue Authority and may lead to a  
faster rescue. Since the last valid GPS position data may stay in the memory  
for up to 4 hours, the user should take care to make sure that the GPS  
position data stored is accurate. This can be accomplished by two methods:  
//  
connected to the beacon before activation, or…  
// By connecting a properly functioning external GPS receiver with a valid  
position fix, and allowing sufficient time to acquire valid GPS position data.  
By always leaving a properly functioning external GPS receiver  
3.  
Testing the external GPS interface  
Connect the optical interface plug to the beacon bezel and allow sufficient  
time for the GPS receiver to acquire valid GPS position data (usually less  
than 1 minute; but it can take up to 20 minutes). Lift the thumb switch to the  
vertical (Self-Test) position and release. Your beacon will confirm that it has  
acquired valid GPS data by displaying the latitude and longitude coordinates  
on the display. This will occur at the end of Self-Test.  
4.  
Updating the external GPS position data  
When the beacon is properly connected to a functioning and compatible GPS  
receiver, GPS position data is automatically updated about every 20 minutes  
while valid GPS position data is present. The operator can force the  
acquisition of new GPS position data by initiating a Self-Test with the beacon  
connected to an external GPS receiver with a valid position fix. This bypasses  
the normal, programmed, waiting time of 20 minutes for the automatic update  
of GPS position data.  
Y1-03-0233DRowenvl.oaDd from Www.Somanuals.com. All Manuals Search And Download.  
27  
If the new GPS position is acquired, the coordinates will be displayed after  
the beacon has completed the Self-Test. If no valid GPS position data is  
available, the beacon will keep the previously stored GPS position data for up  
to 4 hours. In this case, call ACR Customer Service at +1 (954) 981-3333 for  
instructions on how to reset the beacon with the default message.  
A new beacon is programmed with the GPS position data set to a default. If  
the beacon should be activated, this default GPS position data indicates to  
the satellite system that the beacon has no valid GPS position stored in  
memory. Once a functioning and compatible external GPS receiver is  
properly connected to the beacon, the default data will be replaced by valid  
GPS position data, as described in the previous sections.  
5.  
Internal GPS position system  
The GlobalFix™ iPRO is fitted with an internal GPS receiver that will  
determine the coordinates (latitude and longitude) of the beacon’s position on  
the globe, to be transmitted to the Cospas-Sarsat emergency system.  
When the beacon is turned on, the internal GPS is immediately turned on and  
it attempts to acquire positional coordinates. GPS coordinates can be  
acquired any time that the GPS is on, but only valid data is saved. Once the  
beacon acquires valid coordinates, the data is included as part of the next  
transmitted 406 MHz digital message.  
The internal GPS operates on a schedule during which the beacon is on for a  
time, actively acquiring coordinates, and off for a time, in a resting state. The  
schedule is designed to conserve battery but, at the same time, assure that  
navigational coordinates are regularly updated.  
6.  
LED indication of GPS fix  
When the beacon is activated and valid coordinates are acquired, the data is  
included in the digital message of the next 406 MHz transmission. The LED  
blinks green when GPS coordinates are sent.  
If a time period of 4 hours passes without the internal GPS receiver being  
able to update the last good set of navigational coordinates, the message  
transmitted by the beacon will revert back to default data. At this point the  
green LED will stop blinking and the red LED will flash. The internal GPS will  
continue to seek coordinates and when successful the green LED will flash.  
This new data will be transmitted in the next message burst and the green  
LED will continue to flash.

7.  
Compatible GPS receivers  
External GPS interface requirements: In order to be compatible with the  
GlobalFix™ iPRO, an external GPS receiver must provide location  
information according to the following requirements:  
// NMEA 0183, Version 1.5 or higher  
// Baud rate: 4800  
// Talker device identifier: GP (GPS Receiver)  
// Sentence format: GGA (GPS Fix Data)

APPENDIX G - THE COSPAS-SARSAT SYSTEM  
1.  
General overview  
EPIRBs transmit to the satellite portion of the Cospas-Sarsat system. Cospas-Sarast  
satellites are an international system that utilizes Russian Federation and United States’  
low altitude, near-polar orbiting satellites (LEOSAR). These satellites assist in detecting  
and locating activated 406 MHz satellite beacons.  
Cospas-Sarsat satellites receive distress signals  
from EPIRBs transmitting on the frequency of  
406 MHz. The Cospas-Sarsat 406 MHz beacon  
signal consists of  
a
transmission of non-  
modulated carriers followed by a digital message  
format that provides identification data. The 406  
MHz system uses satellite-borne equipment to  
measure and store the Doppler-shifted frequency  
along with the beacon’s digital data message and  
time of measurement. This information is  
transmitted in real time to an earth station called  
the Local User Terminal (LUT), which may be  
within the view of the satellite, as well as being stored for later transmission to other LUTs.  
The LUT processes the Doppler-shifted signal from the LEOSAR and determines the  
location of the beacon, then the LUT relays the position of the distress to a Mission Control  
Center (MCC) where the distress alert and location information is immediately forwarded to  
an appropriate Rescue Coordination Center (RCC). The RCC dispatches Search and  
Rescue (SAR) forces.  
The addition of the GEOSAR satellite system greatly improves the reaction time for a SAR  
event. This satellite system has no Doppler capabilities at 406 MHz, but will relay the  
distress alert to any of the LUT stations. When there is GPS data included in the distress  
message, SAR authorities instantly know your location to within 110 yards (100 m). This  
speeds up the reaction time by not having to wait for one of the LEOSAR satellite to pass  
overhead. Because most of the search and rescue forces presently are not equipped to  
home in on the 406 MHz Satellite beacons signal, homing must be accomplished at 121.5  
MHz.  
Once the 406 MHz signal is relayed through the LEOSAR and/or GEOSAR network, SAR  
forces determine who is closest, and then proceed to the beacon using the 121.5 MHz  
homing frequency.  
2.  
Global Positioning System (GPS)  
The GPS system is a satellite group that enables a GPS receiver to  
determine its exact position to within 30 m (100 ft.) anywhere on  
earth. With a minimum of 24 GPS satellites orbiting the earth at an  
altitude of approximately 11,000 miles they provide users with  
accurate information on position, velocity, and time anywhere in the  
world and in all weather conditions. The GlobalFix™ iPRO stores  
adds this data to its distress transmission, allowing search and  
rescue forces to narrow the search to a very small area, thus  
minimizing the resources required, and dramatically increasing  
the effectiveness of the overall operation.
