ch/scan

Channel Scan Feature

Your GMR1235-2 radio has a channel scan feature
that allows you to easily scan all 22 channels. When
an active channel is detected, the unit pauses on
that channel until the channel is clear. Then after a 2

your transmission, pause slightly after pressing
the

The radio is still able to receive transmissions in this
mode.
