1.3 LICENCE REQUIREMENTS  
The transmitter, as installed in the aircraft, requires an Aircraft Radio Station  
Licence. This licence is obtained by filing the FCC Form 404. While awaiting the  
receipt of the station licence, a copy of FCC Form 404 is kept in the aircraft.  
This equipment has been type accepted by the FCC and entered on the type ac-  
cepted equipment list, as GARMIN GNC 300 and must be identified as GARMIN  
GNC 300 on your Form 404, Aircraft Radio Station Licence application.  
CAUTION  
THE VHF TRANSMITTER IN THIS EQUIPMENT IS GUARANTEED TO MEET  
FEDERAL COMMUNICATIONS COMMISSION ACCEPTANCE OVER THE OPER-  
ATING TEMPERATURE RANGE. MODIFICATIONS NOT EXPRESSLY APPROVED  
BY GARMIN COULD VOID THE LICENCES' AUTHORITY TO OPERATE THE  
EQUIPMENT.  
SECTION 2 INSTALLATION CONSIDERATIONS  
Careful planning and consideration of the suggestions in this section are required to  
achieve the desired performance and reliability from the GNC 300.  
2.1 ANTENNA CONSIDERATIONS  
2.1.1 GPS ANTENNA LOCATION  
The GNC 300 GA 56 Antenna must be mounted on top of the aircraft. For best  
performance select a location with an unobstructed view of the sky above the aircraft  
when in level flight. Figure 2-1 illustrates a typical GPS antenna installation.  
For rotorcraft, locate the GA 56 antenna:  
1) As far from the main rotor hub as possible. This reduces the percentage of time  
the blade blocks the antenna.  
2) Asfarbelowthebladesurfaceaspossibleifinstallingtheantennaundertheblade.  
This reduces signal distortion caused by the blades.

2.1.2 COMM ANTENNA LOCATION  
The COMM antenna should be well removed from all projections, engines and  
propellers. Thegroundplanesurfacedirectlybelowtheantennashouldbeaflatplane  
over as large an area as possible (18 inches square minimum).  
The antenna should be mounted a minimum of 6 feet away from any DME antennas,  
4 feet from any ADF sense antennas, and a minimum of 3 feet from the GNC 300 and  
its GPS antenna.  
TheGNC300COMMantennaconnectorisspecifiedtohaveinstalledGPN330-00067-  
00 (1.57542 GHz notch filter) to minimize interfering harmonics.  
2.1.3 ELECTRICAL BONDING  
No special precautions need to be taken to provide a bonding path between the GPS  
antenna and the aircraft structure.  
Follow the manufacturers instructions for the COMM antenna.  
2.1.4 ANTENNA LIMITATIONS  
GARMIN'S GA 56 Antennas are recommended for installations where the airspeed of  
the aircraft will be subsonic.  
GARMIN's GA 56, Mod 1 or later, must be used.  
See the COMM antenna specification for its limitations.  
2.1.5 VHF COMM INTERFERENCE OF GPS  
On many panel-mounted aircraft, VHF COMM's can radiate strong harmonics from  
the unit and antenna. The GNC 300 COMM section will not interfere with its GPS  
section. However, placement of the GNC 300 GPS antenna relative to all COMM's and  
COMM antenna, including its own, is critical.  
Usethefollowingguidelines, inadditiontoothersinthisdocument, whenlocatingthe  
GNC 300 and its antennas.  
GPS Antenna:  
Locate as far as possible from all COMM antennas  
and all COMMs (including the GNC 300). The GPS  
antenna will be much less sensitive to COMM antennas that  
use a 1.57542 GHz notch filter.  
GNC 300:  
Locate as far as possible from all COMM antennas.

If a COMM antenna is found to be the problem, a 1.57542 GHz notch filter (GPN 330-  
00067-00)maybeinstalledintheVHFCOMMcoax, asclosetotheCOMMaspossible.  
This filter (GPN 330-00067-00) is required for the GNC 300 transmitter).  
If a COMM is found to be radiating, the following can be done:  
1)  
2)  
3)  
ReplaceorcleanVHFCOMMrackconnectortoassuregoodcoaxground.  
Place a grounding brace between the GNC 300, VHF COMM, and ground.  
Shield the VHF COMM wiring harness.  
2.1.6 COMM ANTENNA INSTALLATION INSTRUCTIONS  
The COMM antenna should be installed according to the manufacturer's  
recommendations.  
2.2 RACK CONSIDERATIONS  
2.2.1 ACCESSIBILITY  
Plan a location which gives the pilot complete and comfortable access to the entire  
keypad and which is plainly visible from the pilot’s perspective. Check that there is  
adequate depth for the rack in the instrument panel. A location away from heating  
vents or other sources of heat generation is optimal. Figure 2-2 illustrates a typical  
aviation rack installation.  
2.3 CABLING AND WIRING  
The recommended antenna cable type for both antennas is M17/155-0001 (RG-58A/  
U) per MIL-C-17. Maximum allowable length for the GPS antenna using this cable  
typeis40feet. Othercabletypeswith50 ohmsnominalimpedanceandlongerlengths  
can be used for the GPS antenna, provided the installer insures that the attenuation  
does not exceed 10dB at 1.5 GHz for the specific installation. Check that there is  
ample space for the cabling and mating connectors. Avoid sharp bends in cabling,  
particularly the COMM antenna cable, and routing near aircraft control cables.  
Cabling for the GNC 300 should not be routed near components or cabling which are  
sources of electrical noise.  
Do not route the COMM antenna cable near any ADF antenna cables.  
Route the GPS antenna cable as far as possible away from all COMMs and COMM  
antenna cable.  
2.4 COOLING AIR  
Cooling air is not required for the GNC 300 but is highly recommended because, as  
with any electronic equipment, reduced operating temperature can contribute to  
increased reliability. Additionally, location of the GNC 300 in a stack of other power

* Insert/extract tools from ITT Cannon are all plastic, others are plastic with metal tip.  
Non- GARMIN part numbers shown are not maintained by GARMIN and  
consequently are subject to change without notice.  
NOTE: Alternate contacts for 18 AWG wire: As an alternate to the Positronic  
contacts listed (and provided in the install kit), the installer may use contacts  
made by ITT Cannon as follows: Socket contact - ITT Cannon p/n: 031-10007-  
001, Pin contact - ITT Cannon p/n: 330-5291-055. These contacts require the  
use of a different crimp tool positioner than that shown in the table, with part  
numbers as follows: Daniels p/n: K250, Astro p/n: 616245, or ITT Cannon p/  
n: 980-00005-722.

3.4 RACK INSTALLATION  
A. Figure 3-4 shows outline dimensions for the aviation rack. Install the rack in  
a rectangular 6.320" x 2.000" hole in the instrument panel. Exercise caution  
when installing the rack into the instrument panel. The rack is designed to  
facilitate removal of the GNC 300 for portable use. Deformation of the rack may  
make it difficult to install and remove the GNC 300.  
B. Install the rack in the aircraft panel using four #6-32 countersunk screws and  
four self-locking nuts or other FAA approved methods as per Advisory Circular  
43.13-1A. The screws are inserted from the inside through the holes in the sides  
of the rack (see Figure 3-5).

3.5 GNC 300 INSTALLATION AND REMOVAL  
The GNC 300 is installed in the rack by gently sliding it straight in until it rests  
against the back of the rack. A 3/32 inch hex drive tool is then inserted into the  
access hole at the bottom of the unit face. Rotate the hex tool clockwise while  
pressing on the left side of the Bezel until the unit is firmly seated in the rack.  
To remove the unit from the rack, insert the hex drive tool into the access hole on the  
unit face and rotate counter-clockwise until the mounting screw turns freely and the  
unit protrudes about 3/8 inch from the panel.  
Be sure not to over tighten the unit into the rack. The application of hex drive tool  
torque exceeding 15 in*lbs can damage the locking mechanism.  
3.6 COMM ANTENNA INSTALLATION CHECK  
Check for insertion loss and VSWR. VSWR should be checked with an in-line type  
wattmeter inserted in the coaxial transmission line between the transceiver and  
the antenna. Any problem with the antenna installation will most likely be seen  
as a high reflected power. A VSWR of 3:1 will result in a 25% loss in power.  
SECTION 4 POST INSTALLATION CONFIGURATION & CHECKOUT  
PROCEDURE  
Before starting the below operations, unit initialization must occur. Do this by first  
removing any data cards and then turning the unit on. Press enter in response to  
“Select operating mode Normal ok?”. Press enter in response to “No Jeppesen  
database rte/prx limited to user wpts ok?”. After the satellite status page is displayed  
for 5 seconds the unit may be turned off. Proceed with the following steps.  
4.1 TEST MODE OPERATIONS  
With power applied to the aviation rack and the GNC 300 unit off, depress and hold  
the ENT key and turn the unit on (release the ENT key when the display activates).  
The first page displayed is the Display Test Page. While in TEST MODE, test pages  
can be selected by ensuring the cursor is off and rotating the outer knob either  
direction. To change data on the displayed test page, depress the CRSR key and the  
cursor will highlight the standby COMM frequency. Press cursor again to move to  
configuration selections. The inner knob will change the data on the selected field.  
The ENT key or the outer knob will advance to the next field on the page. Pressing the  
CRSR key again will stop the current field from flashing, allowing the outer knob to  
select the next test page. The ENT key is used to enter a new value into the OBI data  
field after selecting the desired value using the inner and outer knobs (see the  
appropriate chapter of the Pilot's Guide for more information on page and data  
selection). Note that some pages found in test mode are intended for bench testing  
and are not discussed here.

changes.  
The higher the number the slower the display responds.  
“min” sets the minimum brightness of the display. The higher the number the  
brighter the minimum brightness.  
“slope” sets the sensitivity the brightness of the display has to changes in ambient  
light. The higher the number the brighter the display will be for a given increase  
in ambient lighting.

APPENDIX B CONNECTOR CHANGES  
STAMPED CONTACT CONNECTOR USAGE  
Garmin panel mount GPS radios have previously been shipped with stamped crimp type contacts. All  
products are now being shipped with machined mil-spec contacts with color-coded barrels. The following  
figures can be used to identify which type contact you have:  
Some contacts are pins as shown, while others are the socket type. The type used will vary with the  
installation. When working with the stamped crimp type contacts, the following tools should be used:  
Tools  
37 and 9 position connectors  
26 position connector  
supplier  
Amp  
Crimp Tool  
58448-2  
Extraction Tool  
91067-22

Part numbers shown are not maintained by Garmin and consequently are subject to change without notice.  
Special considerations must be made for aircraft power and remote battery (optional) connections, as shown  
in the following diagram:  
Download from Www.Somanuals.com. All Manuals Search And Download.  
REMOTE BATTERY PIN ASSIGNMENTS  
A change was made to the remote battery connectors starting with serial numbers 33050055. Units with  
lower serial numbers have pin contacts on the battery pack. Units 33050055 and up use socket contacts on  
the battery and the pin number assignments are different, however the individual contact locations are  
unchanged. The following table shows the pin assignments for the two different types of connectors:
