To transmit:
1. Make sure that no one else is currently talking on the selected channel;
2. Keep button PTT firmly pressed: TX and To will appear on the display (if
you have set a CTCSS tone, To wan’t be displayed;
3. Before you start talking wait for a fraction of a second then speak normal-
ly, in the direction of the microphone.
4. When you have finished, release the PTT: TX and To will disappear from
the display;
5. When the radio is in reception mode (PTT not pressed) you will automa-
tically receive any communication (RX displayed).
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.
