from other irrelevant parties who are using the same channel.
When you receive a signal that has a tone different from the one set on your radio, you will not hear the
signal. Likewise, signals that you transmit will only be received by parties whose CTCSS/DCS tones are
the same as yours.
Note: Using a CTCSS/DCS channel doesn't mean your calls are private. If other parties' CTCSS/DCS
tones are identical with yours, they can hear your calls.

Busy Channel Lockout (BCL)
Busy Channel Lockout can prevent you from interfering other radios that using the same channel.
Press the PTT button when the channel is busy, the radio with BCL function active will make warning
sound and prohibit transmitting. To stop the warning sound, please release the PTT button and the radio
returns to receiving mode.
The dealer may provide the following two lock mode:
Carrier wave: it will be locked if there is any Carrier wave;
Carrier wave+ CTCSS/DCStransmitting is permitted if there are matched CTCSS/DCS in the channel.
Receiving squelch mode
The dealer may set the condition under which to turn on the speakers:
1. CTCSS/DCS and audio squelch: only when the CTCSS/DCS and optional signaling are patchable.
2. Audio squelch: once the optional signaling is matchable.
3. CTCSS/DCS squelch: when the CTCSS/DCS is matchable.
4. Carrier wave squelch: once there is any Carrier wave.
5. CTCSS/DCS and audio squelch: when the CTCSS/DCS is matchable, or when optional signaling
are matchable.
DTMF signaling
The dealer can set this function by programming.
There are 4 systems of which the parameters can be set, e.g.: group call ID No., * and # sound, etc.
After set a DTMF code in the “code sequence” , select DTMF system in the “DTMF code”, then select
the correspondent DTMF code cable in the “user’s resolution” and transfer it with PTT. Set a DTMF
code in the “deenencoding sequence”, add the sequence into the decoding cable in “DTMF decoding”,
then select the correspondent decoding cable. The dealer may also set the “decoding replay”.
