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.
4.2 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.
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.
If there is no confirmation within 2 seconds by pressing the “E” button, REGATTA 2 will
return to the previously used channel.
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
button, turn the unit on. The display will indicate the band.
4.4b 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. 4.4.a.
2. Press the UP or DOWN buttons on the microphone repeatedly to scroll
through the marine channels until finding the desired channel.
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.
