All Call After programming an all-call key through the CPS, you may enter all-call mode by pressing the key, and then initiate an all call by pressing the ɋPTTɌ key. An all-call should be answered within 3 seconds,otherwise it will be qiutted. An all-call can interrupte an individual call or a group call. 6. Broadcast Call After programming a broadcast-call key through the CPS, you may enter broadcast-call mode by pressing the key, and then initiate a broadcast call by pressing the ɋPTTɌ key. An broadcast-call should be answered within 3 seconds, otherwise it will be qiutted.An broadcast-call can interrupte an individual call or a group call. 7. Receiving a Call By switching to a group set through the NMS, the radio can receive an individual call, a group call or an all call from the group and output voice. 8. Late Entry This function enables the radio to join an undergoing group call after a delay. 9. Priority Call Different call priority can be set on the radio. A radio with a higher call priority initiates a call prior to a radio with a lower call priority. Note: The default call time of all types of calls is 60 seconds, which is modifiable through the NMS. A call is ter…
