When operating in Scan mode, 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.

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.

The radio can be programmed to enable the user to add or remove channels from the
scan list. If user changes are enabled, follow these steps to change the scan list:
1. Turn Scan and Priority Scan off.
2. Select a channel to be added or removed from the scan list by turning the
Channel Selector knob. If the channel is already on the scan list, SCN appears in
the display.
3. Press and hold the [SCN] button for more than 1 second to toggle the channel on
or off the scan list.

scanned sequentially. The selected group is always scanned when Group Scan is
enabled, even if that group is not on the Group Scan List.
When Group Scan is enabled, the following features are disabled:
• Priority Scan
• Dual Priority Scan
• User-Selected Channel Guard
