5.3 Volume control
Turn the knob VOLUME[10] 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[18] described at par. 5.5.
1) Ensure the channel you’ve selected is not a reception-only channel (if it is, the transmission will be disabled) and that no
one else is talking (this will appear on your display as the B
USY icon).
5.4 Transmission and reception
The button PTT[11] is located on the top left side of the device. To transmit:
1) Make sure that the selected channel is not reception-only (if it is transmission will be disabled) and that
no one else is currently talking;
2) Keep button PTT[11] firmly pressed: TX[2] 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 PTT[11]: TX[2] will disappear from the display;
5) When the button is in reception mode (PTT[11] 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[18] button for about 2 seconds. Keep
pressed the button MON/SCAN[18] for about 2 seconds to disable this function.
5.6 Choosing high or low transmission power
Batteries are drained more quickly during transmission. In order to extend the battery life you can select the
low power when transmitting over short distances:
1) Press the MENU[17] button twice and the writing Pr will display.
2) Select LO[8] using the scroll buttons
[19].
3) Press PTT[11] to confirm, or wait for 5 seconds.
If you want to transmit a longer distance repeat the above procedure to select the high power. At step 2
use the scroll buttons
[19] to make the writing LO[8] disappear. When the batteries are in good
conditions, high power is about 5 watt, whereas low power is about 1 watt.
A low battery level during transmission will have a negative effect on the performance of your
device.
5.7 LCD backlight
If there is insufficient light to read the display you can press the MENU[17] button to switch the display
back light on for about 5 seconds.
Switching the back light on the display adds an additional drain on the batteries. Try to make a
moderate use of this.
5.8 Instant selection of Channel 16
Channel 16 is the marine channel most frequently used for emergency. Your transceiver is equipped with a
button that provides instant access to this channel. To recall rapidly channel 16 press the button CH
