injury and/or malfunction of the device.  
3 ABOVE ALL... SAFETY!  
I
I
Do not use REGATTA 2 before connecting a suitable antenna that is in perfect  
working condition – although REGATTA 2 is protected, this may seriously damage  
the stages of transmission power.  
3.1 Symbols used  
For ease and convenience of viewing, REGATTA 2 uses symbols to highlight urgent  
situations, practical advice, and general information.  
Do not use transmit before ensuring proper connection of the antenna. During  
transmission, remain at a minimum distance of 3 feet from the antenna.  
I
Warnings such as this, shown using an open hand symbol, indicate a crucial  
description regarding technical repairs, dangerous conditions, safety warnings,  
advice and/or important information. Ignoring these symbols may result in serious  
problems and/or damage and/or personal injury.  
3.2.b Environmental  
I
Pay attention to ambient conditions – although REGATTA 2 is designed to operate  
under the most severe conditions, it is important to avoid exposure to  
environments that are excessively humid or dusty, or to temperatures outside the  
+5°F to +55°F range. Also avoid exposure to direct sunlight.  
2
Notes such as this one indicate practical advice that we suggest be followed for optimal  
performance with REGATTA 2.  
I
I
Avoid jarring and excessive vibration – REGATTA 2 is built to resist mechanical  
shock and vibration as long as these are within the norm for any electrical device.  
3.2 Warnings

cause an explosion.  
3.2. General  
I
I
I
I
This device has been tested for compliance with Class D digital marine device  
limits. These limits were created to allow for reasonable protection against  
damaging interference.  
3.3 Registration of your Marine Transceiver  
For using GMDSS and DSC functions, the operator must have a GMDSS radio  
operator’s certificate (SRC or LRC) and apply for a ships MMSI number at the local  
radio authority. Without MMSI number the radio can only be used as conventional  
VHF marine radio without DSC. Your distributor may program your radio according  
to your needs.  
This device is to be used solely as an aid to navigation. Its settings may be  
influenced by diverse factors, such as defects or malfunction of the device,  
environmental conditions or improper use.  
It is the user’s responsibility to observe reasonable prudence and judgement in  
navigation, and as such this device should not be considered a substitute for this  
reasonable prudence and judgement.  
Do not open the radio for any reason! REGATTA 2’s precision mechanics and  
electronics require expertise and specialized equipment; for the same reason, the  
radio should under no circumstances be realigned as it has already been calibrated  
for maximum performance. Unauthorized opening of the transceiver will nullify the  
warranty.  
3.2.a Radio Frequency / Installation  
I
Midland recommends following the requirements for prevention of radio frequency  
exposure. Unauthorized changes or modifications to this device may invalidate  
conformity to the FCC Regulations. All changes or modifications must be approved  
in writing by MIDLAND RADIO CORPORATION.

5.4 Selecting an operating channel  
5 BASIC OPERATION  
5.4. With alphanumeric keypad  
1. Ensure that you are in normal operating mode (radio mode), otherwise press  
the “RAD” button several times or press the “C” button until the display shows:  
A “ON”  
5.1 Turning REGATTA 2 on/off  
To turn the transceiver on, rotate the ON/OFF/VOLUME knob clockwise until it clicks  
on. You will hear a beep (acoustic signal) and the LCD display will come on: the  
device is turned on to VHF mode.  
2. Select the desired channel and confirm by pressing the  
E” button.  
To turn the transceiver off, rotate the knob counter-clockwise until you hear further  
2
2
2
If there is no confirmation within 2 seconds by pressing the E”  
button, REGATTA 2 will return to the previously used channel.  
click: the LCD display will turn off.  
A
2
If your transceiver is not connected to a GPS receiver, it is necessary to insert manually  
your coordinates, otherwise an alarm will continue to sound. For further details, see  
par.7.1.  
If a “notexistant” channel is inserted, for example CH99 the radio beeps 4 times after  
pressing the “E”-button, REGATTA 2 returns to the previously used channel.  
To switch between USA, CANada, and INTernational channel lists, turn off the unit, and  
5.2 Volume regulation  
while holding down the  
button, turn the unit on. The display will indicate the band.  
Bring the ON/OFF/VOLUME knob first to medium volume. Once the transceiver  
picks up a signal, adjust the volume to a comfortable level. If no signal is picked up,  
use the squelch control as described in the following paragraph and regulate the  
volume using background noise.  
5.4.a Using the microphone buttons (UP or DOWN)  
1. Ensure that you are in normal operating mode (Radio mode); otherwise  
follow the procedure described in par. 5.4.a.  
2. Press the UP or DOWN buttons on the microphone repeatedly to scroll  
through the marine channels until finding the desired channel.  
5.3 Squelch Regulation  
2
2
Holding down one of the buttons will allow you to scroll quickly through the channels.  
Squelch is used to eliminate the annoying background noise you hear when no  
signal is being picked up. If the squelch is adjusted correctly, there should be  
silence in between calls as well as a reduction in battery consumption. To regulate  
squelch:  
The marine band does not recognize some channel numbers. Refer to the frequency  
table. The channels may have different receiving and transmitting frequencies (duplex  
channels) or may have the same (simplex channels).  
1.  
Rotate the SQ knob completely counter-clockwise until you hear background  
noise (if you don’t hear anything, turn up the volume) and bring up RX on the  
LCD display.  
2
Regulations require that some channels operate on low transmission power (see Chap.1)  
For this reason, REGATTA 2 automatically switches to low power when these channels  
are selected.  
2.  
If no signal is being received (only noise), slowly rotate the SQ knob  
clockwise, stopping as soon as the noise and RX disappear stably.  
5.5 Transmission and reception  
2
If you regulate the squelch level too high (closed), you may hear only background noise  
or intermittent discharges. Correct setting of squelch is also important for reasons  
discussed further on.  
I
Transmitting without a perfectly functioning antenna may seriously damage the  
transceiver.  
The PTT (Push-To-Talk) button is located on the external microphone of your  
REGATTA 2. To transmit:  
1.  
2.  
Ensure that no one else is speaking.  
Hold down the PTT button on the microphone. TXwill appear on the Display.  
Page 14  
Download from Www.Somanuals.com. All Manuals Search And Download.  
3.  
4.  
Wait a second, then speak in a normal voice about 2 inches from the  
microphone.  
If you desire to switch off the backlighting immediately or if you like to reactivate the  
previously inserted level, press the button.  
When you have finished, release the PTT button: TXwill disappear from the  
display. Now REGATTA 2 is in receiving mode (silent and waiting for a  
signal) where it will automatically receive any communication.  
5.6 Selecting high and low transmission power  
The transmission phase absorbs the most energy. To reduce the risk of wearing out  
the battery, we recommend selecting low transmission power when transmitting over  
short distances. Hold the H/L button down (on the radio): Lo(low power) appears  
on the display. When transmitting or receiving over long distances or with weak  
signals, press the H/L button again. Lowill be replaced with Hi(high power) on the  
display.  
2
2
When the transceiver is tuned to a channel limited to low output power, pressing the H/L  
button has no effect.  
In the standard mode, REGATTA 2 switches 25 W during high power output and 1 Watt  
during low power output. Only on channels 15 and 17 the radio always reduces  
automatically - according to the international agreements for maritime radio – to a value  
under 1 Watt.  
5.7 Instant recall of channel 16  
Channel 16 is a security and distress channel. This channel is used to establish  
initial contact with another station and for emergency communication. This channel  
can be called up at any time by pressing button 16 on both the transceiver. To  
return to normal operations, select another channel using the alphanumerical keypad  
or the UP/DOWN buttons on the microphone. By pressing a second time the 16  
button, the radio returns to the previously used channel before selecting channel 16.  
I
Do not transmit on channel 16 unless absolutely necessary. Doing so may impede  
emergency operations.  
5.8 Display lighting  
If ambient lighting is insufficient for reading the display, the LCD display backlighting  
can be adjusted. Hold pressed the button until a desired level is reached or until it  
has been completely turned off.  
If the backlighting is activated, the display shows “LITE”.  
The chosen level of backlighting remains stored, also in case of extinction  
and successive turning on the radio.

The scanning can be stopped by pressing the buttons C, or button 16 on the  
microphone or by sending out a DISTRESS call. Your transceiver will stop on  
the current channel (if you pressed button C) or on channel 16 (if you pressed  
16 or PTT on the microphone).  
6 SCANNING FUNCTIONS  
2
Note: Scanning does not function correctly if the squelch is not regulated as described in  
par.5.3.  
6.1 Channel scanning  
REGATTA 2 can automatically search for signals throughout the marine band by  
scanning, or selecting the channels in rapid sequence. When a signal is detected,  
the scanning pauses on that channel and remains blocked until the signal ends.  
Before the scanning automatically starts again, REGATTA 2 waits for a few seconds  
in case the user wishes, if necessary, to respond to a call even if in truth you will see  
the channels being scanned.  
6.2 Dual Watch and Triple Watch  
The meaning of these terms are:  
·
Dual Watch – allows the user to remain tuned to a channel of choice while  
periodically performing an automatic verification of signals on channel 16.  
The REGATTA 2 scanning happens with a minimum of 2  
channels to a maximum of 56 channels on the INT band  
(channel 70 is not selectable).  
·
Triple Watch – as written above, including a third channel chosen by the user.  
6.3 Activation of Dual Watch/Triple

be monitored and the display will show the script “M/S” – which indicates  
the scanning of the stored channels, - “Adv” and “Del” in relation to the 2  
function keys. Every time a signal/disturb is found on a channel, the  
scanning stopps for a few seconds in order to give the user a chance to  
respond to the call or to cancel the channel, if necessary.

7 USE WITH GPS  
8 DIGITAL SELECTIVE CALLING (DSC)  
7.1 Function  
8.1 Introduction  
If connected to a GPS receiver, the transceiver will display the vessel position  
(latitude and longitude), as well as time data. If information regarding position data  
are not received, in the normal radio mode, time data does not appear and a minute-  
long warning tone will sound (can be deactivated by pressing any button). This tone  
will sound every 4 hours, reminding the user that position data needs to be inserted.  
The user may also insert the coordinates manually as described in par. 10.6.  
Digital Selective Calling is a semiautomatic method for controlling VHF, MF and HF  
radio calls. It was also designed as part of the global marine security and  
emergency response system (GMDSS). It is likely that DSC will eventually replace  
audio calls on emergency frequencies and will be used to send urgent and routine  
radio-transmitted maritime security information. This new service will allow crafts to  
send/receive calls of an emergency, urgent, security, or routine nature to/from  
vessels equipped with a DSC transceiver.  
7.2 GPS information on the display  
I
To avoid accidentally sending a distress call or a call sent incorrectly, contact your  
vendor or local authorities for updates on DSC operating and emergency  
procedures.  
Refer to the following illustrations:  
I
In European inland waterways DSC-function is not allowed.  
8.2 Mobile Marine Identification Service (MMSI)  
2
Important! To send/receive DSC calls, the user must program his personal MMSI code  
into the transceiver. This is a nine-digit number used by marine transceivers equipped for  
DSC digital selective calling. This number is used much like a telephone number for  
contacting other, specific vessels. For further details on programming your MMSI, see  
par. 10.10.

Position indicator  
Displays GPS or manually inserted co-ordinates.  
Time indicator  
Shows data supplied by the GPS or the transceiver’s clock.  
8.3 Navigating the DSC menu  
7.3 Customized setup  
Some GPS receivers may require a change in the manner the radio processes the  
GPS data. Pressing GPS selection diplays CHECKSUM ON/OFF selection.  
REGATTA 2 offers many DSC functions. For this reason it was created a specific  
menu of settings and activations accessible via the function keys as follows:  
1. Access the “CALL”-Menu by pressing the related function key.  
2. Press the function key corresponding to the word “Type” to select  
the type of desired call.  
If no GPS receiver is connected, using WARN BEEP ON/OFF allows the user to  
defeat the audible warning that new position data is required. Press C button to  
return to menu.

8.4 Individual call (Routine To)  
The user can carry out an individual call to a specific DSC station (a vessel or a  
costal station). To carry out calls, you have to enter the MMSI code manually or  
recall it from the preprogramed MMSI directory. For further details on programming  
the MMSI directory, see par. 10.5.
