Operation Manual

28
Move the switch once to activate the function. Move the same switch to cancel.
7) MODE:
Use this key to select AM or FM. The modulation mode must correspond with that of the
person with whom you communicate.
A/ Amplitude Modulation (AM) is for communications in areas where there are obstacles
and over medium distances.
B/ Frequency Modulation (FM) is for nearby communications in flat, open areas. It gives
better quality of communication (squelch adjustment needs more finesse).
8) CH 19:
Channel 19 AM is automatically selected when you activate this switch. To activate this
function, move the switch, and to return to the previous configuration move the same
switch again.
9) 6-PIN MICROPHONE PLUG:
This plug is situated on the front panel, thereby making it easier to set the equipment
into the dashboard. See the cabling diagram on page 46.
10) PTT (push to talk):
Depress this knob to transmit a message and release to listen to an incoming
communication.
