CTCSS & CDCSS 
CTCSS/CDCSS allows you to ignore unwanted calls from other parties using the same 
channel. 
When CTCSS/CDCSS is set, the user can only receive the calls on the same channel with 
same CTCSS/CDCSS.   
The dealer can preset CTCSS/CDCSS signaling on certain channels. 

Note: 

Although using CTCSS/CDCSS enables you to avoid hearing unwanted calls, it 

does not mean your calls will be private. 

Channel Scan (This feature can be disabled by your dealer) 
Turn channel selector knob to the position “16”, the radio will automatically detect those 
channels which have been programmed as scan items in channel 1-15 (your dealer can 
set any channel as scan item or non-scan item). When any activity is detected on one 
channel, the radio will stop on the active channel for communications. 

Priority Channel Scan 

Any programmed channel may be set as the priority channel. The radio will detect the 
priority channel periodically while stopping on a non-priority channel. When there is any 
activity on the priority channel, the radio will turn to the priority channel for 
communications. 

Scan Revert Channel 

When the radio is scanning, press the PTT key, it will transmit in pre-programmed revert 
channel. 
Revert channel can be programmed by your dealer. 

Busy Channel Lockout 
If the current channel is set by your dealer as “busy channel lockout”, and this channel is 
being used by other users, press PTT, the radio sounds a beep and will not transmit the 
signal. To stop the beep, release PTT.    When this channel is free, press PTT to transmit.
