A scan channel list must be created before SCAN can be used. The radio will not go into SCAN mode
where no scan channels are programmed. The scan channel list can be established in PC program of
Menu mode.
Normal Scan
Once SCAN is activated, the radio will perform a normal scan mode. When the scan channel list is NS1,
NS2 and NS3 on the normal scan mode, the radio proceeds to scan in the sequence of NS1, NS2, NS3,
NS1, NS2, NS3.... During the receiving mode user can move to the next channel by pressing the “F1” or
“F2” buttons. And delete current receiving channel temporarily from the scan channel list.
If getting out of SCAN Mode or turning on power again, the list deleted temporarily is returned back to
the original.
Priority Scan
As soon as priority scan channel is detected, the radio will change priority scan mode. When the scan
channel list is NS1, NS2, NS3 and priority scan channel is PS, the radio proceeds to scan in the sequence
of PS, NS1, PS, NS2, PS, NS3, PS, NS1....
During receiving signal through common channel, the radio scans the priority channel periodically. And if
the radio detects the signal on the priority channel, it starts to receive the signal from the priority channel.
During the receiving mode user can move to the next channel by pressing the “F1” or “F2” buttons. The
user can delete current receiving channel temporarily from the scan list and at that time, user can move to
the next channel. But the radio receives the signal from priority channel then it will not be deleted.
