Advanced Functions
Monitor
This function can be enabled by programming Side key (8) (default setting).
When no signal is received, the Squelch circuit automatically disables the speaker, so the background
noise desappears. To manually disable the Squelch, press the SIDE key (8). This function may be
useful when you want to adjust the volume, when you want to receive a weak signal or when you want
to listen to a channel screened by CTCSS/DCS. If the Side key (8) is pressed, the Led indicator (6)
lights in green color.
Tone Squelch Function (CTCSS) / (DCS)
Reserved Transmission (CTCSS) & Digital Reserved Transmission (DCS)
1. Any channel may be associated to a programmed private protection CTCSS/DCS tone. A
CTCSS/DCS tone is a sub audible tone which allows to cut off and therefore not to listen to
signals transmitted from other users on the same operating channel.
2. When you receive a signal which has a tone different from the one which has been programmed
on your radio, you will not listen to this signal. For the same reason, your outgoing messages can
only be received by other radios which have the same tone as yours on that channel.
Note : Even if the use of a CTCSS/DCS tone will protect you from receiving unwanted signals, the
privacy of your transmissions is not guaranteed.
Automatic Channel Scanning
This function can be enabled by programming Side key (8).
To operate this function, you must program the channels to be scanned.
Press the Side key (8) to start scanning. Scanning will stop whenever a signal is received. You can
press PTT key (7) to transmit.
To stop scanning, press Side key (8) again.
