About Scanning
The scan feature is used to monitor groups of channels or talkgroups for activity of interest. This means that you are
able to operate across multiple channels or talkgroups at the same time. For example, you may need to monitor your
own conventional dispatch channel as well as other local area channels, such as a local sheriff and highway patrol
channel.
Members of a scan group may be conventional channels (P25 or analog), trunked talkgroups, and vote groups,
depending of the type of scan group. When scanning is active, the radio searches through member channels for activ-
ity. If activity is found, the radio remains on that channel or talkgroup, so that you can hear the activity, and respond if
necessary. Once the activity has finished, the radio begins searching again.
Some channels or talkgroups, known as ‘priority’ channels or talkgroups, are scanned more often that others in the
scan group. Calls from priority channels or talkgroups take precedence over those from non-priority group members.
While the radio is scanning for activity, the animated icon appears on thedisplay.
When the radio stops on a channel or talkgroup where there is activity, the icon flashes.
In a background or talkgroup scan group, a scanning icon with a tick ( ) indicates that the selected channel or
talkgroup is a member of the scan group.
The four types of scanning that may be available are:
• standard scanning (P25 conventional and analog channels)
• background scanning (P25 conventional and analog channels, and may include some voting groups)
• in-zone scanning (P25 conventional and analog channels, and P25 trunked talkgroups)
• talkgroup scanning (P25 trunked talkgroups, and may include some P25 conventional and analog channels,).
