BACKGROUND OPERATIONS
CTCSS / DCS Encode / Decode
Users can set independent CTCSS / DCS encode / decode for every channel by programming
software.
Optional Signaling
Users can enable or disable the Optional Signaling in every channel by programming software.
This Signaling function is similar to CTCSS/DCS which embodies functions as Selective Call, Group
Call, All Call, PTT ID, and Remotely stun and Waken.
1. PTT ID: If current channel is edited with PTT ID, the transceiver will send transmitting ID when
pressing or releasing PTT key.
You can set group call wildcard for each group2. by programming software . (DTMF character A.
B.C.D.*** or “#”).
The caller can call different groups by sending different group call codes. When the receiving
party receives a valid ID code, one or all of the characters would be replaced by wildcard characters
and the receiving part can realize all call, group call or selective call. It is much easy and exible to
realize all call, group call and etc by using group call code.
For example:
Group code –"C"
Radio A Radio B Radio C Radio D
ID code of the receiving party is 123 223 235 355.
If the calling party uses "C23" to call, Radio A and Radio B will receive the call.
If the calling party uses"CC5" to call, Radio C and Radio D will receive the call.
If the calling party uses "CCC" to call, All Radios would receive the call..
