Advanced Functions
Decode Continuance Time
During Scan process, when a signal is detected on one channel, if transceiver can' t decode
successfully, it will resume to scan next channel.
Note : This function is programmed by PC software and it is available only in CHANNEL MODE.
CTCSS / DCS FUNCTION
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.
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.
50 CTCSS tones and 83 DCS groups are available.
CTCSS / DCS Encode
To transmit a signal with a CTCSS or a DCS Tone, enter the MENU Mode and select the CTC/DCS
function setup. Select and confirm the ENCODE option and use the Rotary Switch (4) to select the
desired CTCSS or DCS tone number or select OFF to disable the function.
Press MENU Key (4) to confirm the desired tone number and press the EXIT Key (6) to return to
CTC/DCS function setup. Press the EXIT Key (6) again to return to Stand-by mode.
CTCSS / DCS Decode
To receive a channel which has a CTCSS or a DCS Tone associated, enter the MENU Mode and select
the CTC/DCS function setup. Select and confirm the DECODE option and use the Rotary Switch to
select the desired CTCSS or DCS tone number or select OFF to disable the function.
Press MENU Key (4) to confirm the desired tone number and press the EXIT Key (6) to return to
CTC/DCS function setup. Press the EXIT Key (6) again to return to Stand-by mode.
When a CTCSS or DCS decode tone is selected, the CT (B) or DCS (C) Icons wiil appear on LCD
Display (3).
2-TONE / 5-TONE / DTMF
Many repeaters can be activated by sending 2-Tone / 5-Tone / DTMF codes. For further information,
consult your local dealer.
Note : These functions are programmable by using the PC software.
