Volume adjustment
As soon as the radio receives a signal, you can adjust the volume to a comfortable
level thanks to the ▲ o ▼ controls. If no signal is detected, you can use the squelch
as described in the following paragraph.
Squelch adjustment
This function allows to adjust the squelch in 10 dierent levels:
• Level 0: open squelch. With the squelch open, all signals , even the weakest
ones, are received as well as the background noises.
• Levels 1- 9: level 1 (lowest squelch), level 9 (highest level of squelch).
If you set the squelch at the highest level, you will only hear the strongest signals.
1. Press the MENU button for three times.
2. The display will show “SL” followed by a number that identifies the squelch
level.
3. Select the desired level by pushing the ▲/▼ controls, then confirm with PTT
(or wait for 4 seconds).
Transmission and reception
When you press the PTT the transceiver transmits with high or low power (depen-
ding on the setting of the MENU: “H” or “L”).
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;
3. Before you start talking wait for a fraction of a second then speak normally, 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 automatically
receive any communication (“RX” displayed).
During transmission and reception try, as far as possible, to keep the antenna in verti-
cal position and to avoid obstacles towards the direction of the other party.
Scanning all channels
777 PRO can automatically search for signals throughout the PMR/LPD bands by
scanning, i.e. selecting the channels in rapid sequence.
When a signal is detected, the scanning pauses on that channel and you can transmit
by pushing PTT . If you press PTT during scanning you can transmit on the channel
from which the scanning started.
The scroll buttons ▲/▼ allow you to change the direction of scanning (from lower
