SCAN

Your radio is equipped with the Scan feature, which allows you to monitor multiple channels/ talkgroups for voice activity. The radio will stop on a channel/talkgroup when it detects activity on it.

Your radio automatically switches to a channel/ talkgroup, within the scan list, when it detects activity.

The LED indicator blinks green during scan mode; it stops blinking when the radio switches to an active channel/talkgroup.

There are two ways that your radio scans:

System Scan (manual)

Auto Scan (automatic)

TALKBACK

The Talkback feature allows you to respond to a transmission while scanning. If transmission is detected on a channel/talkgroup while scanning, the radio will stop on that channel/ talkgroup for a default 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 blinking while the radio is in hangtime. If the PTT button is not pressed after the prepro- grammed hangtime, the radio returns to scanning channels/talkgroups.

START SYSTEM SCAN

Press the preprogrammed Scan button to start scanning channels/talkgroups in your scan list (if Auto Scan is not enabled) (see page 18).

STOP SYSTEM SCAN

Press the preprogrammed Scan button to stop System Scan (see page 17).

Note: Your dealer/programmer can preprogram your radio when exiting System Scan to automatically revert either to the last scan channel/talkgroup that had activity on it or to the channel/ talkgroup where scan was initiated.

START AUTO SCAN

Auto Scan automatically starts scanning once a channel/talkgroup with Auto Scan enabled is selected.

Select a channel/talkgroup that has been preprogrammed for Auto Scan by your dealer/ programmer.
