5.1 Dual Channel
Dual channel scans two channels for communications. One channel is a normal
VHF channel and the other is CH16. The following is how the DUAL CH feature
works when a signal is received on one of the channel:
 If a signal is received on the normal channel, the radio quickly switches
between the normal channel and CH16 to look for a transmission.
 If a signal is received on CH16, the radio stops and listens only to CH16 until
communication ends and then starts DUAL CH scan again.
