7.22 SCANNING

7.22.1 Selecting Scan Modes

Three scanning modes are available for the radio, but only one can be active at any time. Changing the

scanning mode changes the way the radio scans voice calls for all of the profiles in the radio personality,

no matter which profile is or becomes active.

The choice of scanning mode broadens or narrows the span of communications with all the groups in

profiles you listen to, but does not affect your interaction with those groups you talk with.

The scanning modes available for selection may be limited to a subset of the three scanning modes by the

administrator.

Table 7-6: Scan Modes

SCAN

MODE EXPLANATION

No Scan

Eliminates distractions.

Full communications (listen and talk) with the active talk group.

No calls received from other talk groups.

Normal

This is the default setting.

The user can scan all talk groups in the active profile that are not locked out as long as there

is demand on the site.

Priority (P1 and P2) groups are user selectable.

Receive calls from more than one talk group, if available from the current site.

Allows dragging of the selected talk group, P1, P2, and default emergency talk groups to the

site on which the radio is registered. (If other calls are available at the site, they also can be

heard but they will not be actively dragged.)

The default emergency talk group, as well as any emergency-enabled talk groups, is only

dragged if it is in emergency mode.

Fixed

The priority groups are fixed to the selected profile’s pre-defined P1 and P2 groups

(configured via the UAS). In this mode, P1 and P2 groups CANNOT be locked out.

The user can scan all talk groups in the active profile that are not locked out, as long as there

is demand on the site.

Allows dragging of the P1, P2, and selected talk group to the site on which the radio is

registered. If other calls are available at the site, they can also be heard, but they will not be

actively dragged.

The default emergency talk group, as well as any emergency-enabled talk groups, is only

dragged if in emergency mode.

The scanning mode choice remains in effect until it is changed. Even if the radio is turned off, the current

scanning mode selection is saved for the next use.
