3.2 Location for the transceiver
Before continuing, look for a place to install the transceiver which:
• Is far enough away from any device sensitive to magnetic/electromagnetic
fields (e.g. compass) in order to avoid interference during their use.
• Allows for accessibility to the front panel of REGATTA 2.
• Provides easy connection to a power supply, for the antenna and for other
cables.
• Has sufficient space close by for installation of the microphone support.
• Allows for mounting of the antenna at least 3 feet from the transceiver.
The supplied universal mounting bracket allows for mounting of the transceiver high up
(with the bracket above the device) or on the bridge (with the bracket below the device)
with an angle range of 45°.
, Warning! Installation and connections must be performed in part by qualified
persons.
3.3 Mounting the transceiver
To mount the transceiver to your vessel (see following picture):
1. Choose an appropriate location, as explained in the paragraph above.
2. Position the mounting bracket on the surface upon which it will be fixed, use a
pencil to draw the position of the four holes where the screws will be inserted.
, Ensure that the surface inten ded for the transceiver mou nting can be drilled into
without damaging other parts of the vessel and be careful to not drill right through
it.
3. Remove the bracket, drill four holes smaller in diameter than the screws, and
reposition the mounting bracket, aligning it with the four holes.
4. Screw in the mounting screws and ensure the bracket is fixed firmly, using the
screws, the grained washers, the flat washers and the nuts supplied.
, If you are not able to reach the back part of the bracket surface to fix the nuts onto
the screws, use wood or sheet-metal screws to fix the bracket.
5. Tighten the screws with a screwdriver so that the bracket is firmly fixed to the
surface.
6. Align the transceiver on the bracket, ensuring the holes of the internal part of
the bracket line up with those on both sides of the transceiver (you can choose
the preferred notch in order to best adjust the angle of the transceiver’s front
panel for ease of viewing and use (15

3.4 Adjustment of angle
To change the angle of inclination after installation:
1. Loosen the mounting knobs on the sides of the bracket.
2. Adjust the transceiver to a better angle, lining up the holes of the internal part
of the bracket with those on both sides of the transceiver.
3. Tighten the knobs to fix the transceiver into place.
3.5 Installation of the antenna/electromagnetic exposure
For optimal radio settings and minimal user exposure to electromagnetic radio
frequency energy, ensure that:
• The antenna is connected to the transceiver and is properly installed.
• The antenna is situated away from people and is positioned at least three feet
from the transceiver and microphone.
• The connector is a standard PL259 (male UHF).
3.6 Mounting of Microphone
To install the microphone mount, look first for a mounting point close to the
transceiver. The distance between the transceiver and the wall mount must be less
than the length of the microphone cable.
, Do not pull excessively on the microphone cord.
This part is impo rtant to the correct opera tion of
the radio: over time, pulling may damage the cord
and impede the user from transmitting.

3.7.c Antenna
The antenna is an extremely important part of the device and noticeably influences
the settings of any telecommunications device. Contact your supplier regarding the
antenna and request advice about how to mount and best connect it to your
transceiver.
, Warning! Ensure the antenna is in perfect working order. It may otherwise
seriously damage the radio! A periodical measurement of the stationary waves is
advised using a suitable SWR meter.
3.7.a Power Supply
The transceiver power supply must be 12V DC (see Technical Specifications,
Sec.12). The red cable must be connected to the positive pin, the black to the
negative pin.
, Warning! A faulty connection may seriously damage the radio!
, The power cable is equipped with a protection fuse. If the fuse s horts, look for it s
reason before substi tuting the cable with a new one of the same type and value.
Never short-circuit i t, as this may damage the radio.
3.7.b GPS device
If your REGATTA 2 transceiver is connected to a GPS receiver, you can obtain and
view NMEA information relative to the current position the vessel (latitude and
longitude) and the local time with respect to Greenwich Mean Time (GMT).
Page 13
4. BASIC OPERATION
4.1 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.
To turn the transceiver off, rotate the knob counter-clockwise until you hear a click:
the LCD display will turn off.
If your transceiver is not connected to a GPS receiver, it is necessary to manually insert
your coordinates, otherwise an alarm will continue to sound. For further details, see
Par.6.1 & 6.3.
4.4 Selecting an operating channel
4.4a 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 looks like FIG. A.
2. Select the desired channel and confirm by pressing
the “E” button.
3. To select a channel with A or B suffix, an A or B will
appear next to a key. Press the key for the letter,
then press the “E” button.
4. To select a weather channel for reception (USA or CAN only), press a
number key, then press and hold the WX+ key until the desired channel is
found. Press the “E” button to confirm.
Fig. A
4.2 Volume regulation
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.
4.3 Squelch Regulation
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:
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. If no signal is being received (only noise), slowly rotate the SQ knob
clockwise, stopping as soon as the noise and RX disappear.
If you regulate the squelch level too low (open), you may hear only background noise.
Correct setting of squelch is also important for reasons discussed further on.
If there is no confirmation within 2 seconds by pressing the “E” button, REGATTA 2 will
return to the previously used chann el.
If a non-existant 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
while holding down the
4.4b Using the microphone buttons (UP or DOWN)

button, turn the unit on. The display will indicate the band.
Holding down one of the buttons will allow you to scroll quickly through the channels.
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).
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.
4.5 Transmission and reception
, Transmitting without a perfectly functioning antenna may seriously damage the
transceiver.

4.7 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 alphanumeric 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.
, Do not transmit on channel 16 unless absolutely necessary. Doing so may impede
emergency operations.

5 SCANNING FUNCTIONS
• The scanning can be stopped by pressing the “C ” button, or “16” button on the
microphone or by sending out a DISTRESS call. Your transceiver will stop on
the current channel (if you pressed the “C” button) or on channel 16 (if you
pressed 16 or PTT on the microphone).
5.1 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.
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).
• In order to execute the scanning of the marine
channels, it is necessary to create a list of channel s
for scanning. Operate in the following way:
1. Select a channel you desire to insert into the scanning list.
2. Press and hold the “SCAN” (Fig. B); button for 2 seconds; the radio beeps
twice and on the display appears for a short time,
then the words “Scan Ena” (Fig. C) appear.
3. If you desire to cancel a channel from the scanning
list, repeat the procedure as described at point 2. In
that case the display is showing “Scan Inh”.
4.
Once created your list, you can activate the
scanning by pressing the function key corresponding to the word
(Fig. C).
• If you want to eliminate (useful if there are distortions) or to exclude
momentarily (useful for undesired conversations) a channel during scanning,
operate as follows:
• DEFINITIVE EXCLUSION OF A CHANNEL:
If your REGATTA 2 is operating on a busy
channel, press the “Inh” (Fig. D) . function key.
• TEMPORARY R EMOVAL OF A CHANNEL:
Press the function key corresponding to the written “Adv” to advance the
scanning and to temporarily remove this channel from the scanning list. At the
end of the complete scanning cycle, the channel previously jumped will be
monitored again.

Fig.D
Note: Scanning does not function correctly if the squelch is not regulated as described in
par.4.3.
5.2 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.
• Triple Watch – as written above, including a third channel chosen by the user.
5.3 Activation of Dual Watch/Triple
To activate Dual or Triple watch:
• Dual watch - Select a desired channel and press the D/W-button. The Display
will indicate “D/W” and you will see the two monitored channels.
The Dual Watch function can be stopped in 5 differe nt modes: by pressi ng the PTT-
or the “16” buttons on the microphone, “D/W”- or “C”-buttons or by sending out a
DSC-call.
• Triple watch – select one of the 2 channels you desire to monitor together with
channel 16. Hold pressed the function key corresponding to the indication T/W
until you hear two beeps. Now “User” appears on the display. (Fig. F). Move
now to the second channel you desire to monitor, press the function key
corresponding to T/W. Now you will see all three channels sliding on the
display with indication T/W. “Adv” appears too, that, similar to SCAN function,
has the aim to exclude momentarily the monitoring of
the current channel.
The Triple Watch function can be stopped by pressing the
“C” button, the PTT- or the 16-buttons or by sending out a

Similar to scanning of marine channels, Dual Watch and Triple watch stop when a signal
is found and remain blocked for a few seconds after the signal disappears, in order to
give the user a chance to respond to a call, if necessary.
Dua l/Triple Watch cannot function co rrectly if the squelch is not correctly r egulated, as
described in par .4.3
Memory channels (MEM mode)
5.4 Memory scanning (SCAN MEMORY)
1. Similar to the scan function, memory scan will
cycle sequentially through the channels, but
only those, which have been pre-selected (at
least 3).
2. Press the “M/S” function key (Fig. G). The radio emits 2 beeps and “M/S
Sel” appears on the display for about 2 seconds
(Fig. H).

inserted into scan cycle, select the channel press and hold the “M/S”
function key until the display shows “M/S Del”. (Fig. I) .
4. Once all channels are stored, the scanning can begin (SCAN MEMORY):
Press the function key corresponding to the written “M/S”. The channels will
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.
Note: Scanning does not function correctly if the squelch is not regulated as described in
par.4.3.
5.4a Reception/Transmission during SCAN MEMORY
• Reception: If REGATTA 2 finds a signal the scanning interrupts. The display
indicates “RX” instead of “M/S” and the communication will be received through
the loudspeaker.
• Transmission: It is possible to transmit at any time, also when the scanning is
active. In that case REGATTA 2 will always transmit on channel 16; if instead
the transmission is done after a signal has been found, the device will transmit
on the previously busy channel. After the transmission the scanning comes
interrupted.
5.4b To delete/To jump a pre-selected channel in memory
If during the scanning a signal is received on an undesired or disturbed channel, it is
possible to temporarily cancel the channel or to skip the channel momentarily.
In order to execute these functions, the radio must be syntonized on a channel (firm
scanning). Through the two function keys corresponding to “Adv” and “Del” you will
have the possibility to jump the busy channel respective to cancel it from the preselected list of channels.
There are 4 modes to stop the scanning of channels in memory:
1. By pressing the PTT-button.
2. By pressing the 16 button on the microphone or on the front panel
3. By pressing the C-button.
4. By sending out a DSC-Call.

7 DIGITAL SELECTIVE CALLING (DSC)
7.1 Introduction
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.
, To avoid accidentally s ending a distress call or a call sent incorrectly, contact your
vendor or local authorities for updates on DSC operating and emergency
procedures.
, In European inland waterways DSC-function is not allowed.
7.2 Mobile Marine Identification Service (MMSI)
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. 9.10.
7.3 Navigating the DSC menu
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.
Once inside a sub-menu, you can return at any time to the main menu by pressing the C-
button and terminating the current operation.
7.4 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 pre-programmed MMSI directory. For further details on
programming the MMSI directory, see par. 9.5.
Page 18
7.4 Sending an individual call
You can carry out an individual call using the following procedure:
5. Press briefly the function key corresponding to
CALL. On the display appears:

In this case the answer is reached from ship 100000000 and the possible
communication channel will be CH06.
To confirm the reception of the received message, REGATTA 2 will emit an acoustic
message that can be interrupted by pressing the function key corresponding to ”OK” or
“STOP”.
Pressing OK beyond interrupting the acoustic signalling, REGATTA 2 is set to the
chosen communication channel (in our example 06).
If no function key comes pressed at that time (1 minute)
extinguish automatically.
− If the call is not acknowledged, the display will indicate
(M) ; by pressing the function key corresponding to
“Stop” the radio will return to the normal radio mode.
