STARTING OR STOPPING SCAN The green LED indicator flashes during a scan operation and stops flashing when the radio switches to a channel. 1 Note: The same channels can be assigned to different scan lists.
TALKBACK SCAN The Talkback feature allows you to respond to a transmission while scanning. If transmission is detected on a channel while scanning, the radio will stop and land on that channel for a preprogrammed period of time after activity has ceased. This is referred to as “hangtime”. During this hangtime you may respond by pressing the PTT button. Note: The LED scan indicator stops flashing while the radio is in hangtime.
