3.3.2 Transmit With Scan On
When Switch B (scan) is up, the radio transmits on the channel selected by the
channel selector knob.
1. Select a transmit channel by turning the channel selector knob.
2. Press and hold the PTT switch and talk in a normal voice. When the PTT
switch is released, the radio continues to monitor the selected channel for the
preset scan delay time before it resumes scanning.
3.3.2.1 Talkback Scan
If your radio is programmed for Talkback Scan, press PTT while a channel is
active or while scan-delay time remains. You will be responding on the transmit
frequency of the received channel.
Talkback Scan will not work if Priority Scan is also on and your radio is
programmed to always transmit on the Priority 1 channel.
