If a distress signal is received on channel 70, the transceiver
monitors channel 16 and 70 alternately until the distress sig-
nal disappears. If a signal is received on another channel,
DSC watch pauses until the signal disappears.
This function may not be available for some channel
groups depending on dealer setting.

on the transceiver and microphone can be deactivated.
