5. Basic operations
5.1 Turning on/off
To turn on the transceiver, turn the ON/OFF/VOLUME knob clockwise until you hear it clicks: the
LCD display will light up and do an Auto-Test. Subsequently you will hear 1 beep. To turn off the
transceiver, turn the knob counter-clockwise until you hear another click.
5.2 Selection of the operational channel
1) Press once the MENU button. The number of the channel will start flashing on the display.
2) Press the / buttons to scroll up or down the channel list till you select the desired channel.
3) Press the PTT button to confirm, or wait for 10 seconds.
Refer to the table of frequencies. Moreover, the reception frequency could be different (duplex
channels) from the transmission frequency or it could be the same (simplex channels). Normally
communications among vessels can only take place on simplex channels.
5.3 Volume control
Turn the knob VOLUME to about half way and adjust it to a comfortable level as soon as you
receive a signal. If you do not receive a signal you can use the button MON/SCAN described at
par. 5.5.
Ensure the channel you've selected is not a reception-only channel (otherwise the transmission will
be disabled) and that no one else is talking (this will appear on your display as the BUSY icon).
5.4 Transmission and reception
The button PTT is located on the top left side of the device. To transmit:
1) Make sure that the selected channel is not reception-only, (otherwise the transmission will be
disabled) and that no one else is currently talking;
2) Keep button PTT firmly pressed: TX will appear on the display;
3) Before you start talking wait for a fraction of a second then speak normally, in the direction of the
microphone, and hold the device at a distance of about 5 cm.
4) When you have finished release the button PTT: TX will disappear from the display;
5) When the button is in reception mode (PTT not pressed) you will automatically receive any
communication;
During transmission and reception try, as far as possible, to keep the antenna in vertical position
and to avoid obstacles towards the direction of the other party.
5.5 Button MON (Monitor)
The Monitor button is for temporarily excluding (opening) the squelch, in order to listen to signals
that are too weak to keep the squelch permanently opened. By excluding the squelch you will avoid
listening the communication "chopped" by the squelch. In order to activate the Monitor function, so
as to listen to all traffic on the selected channel, keep pressed the MON/SCAN button for about 2
seconds. Keep pressed the button MON/SCAN for about 2 seconds to disable this function.
