GROUP SCAN OPERATION

Only Groups that are part of the radio's scan list may be scanned. Groups are added to the scan list on a per system basis by PC Programming, the radio keypad or both, dependent upon programming. This scan list may be changed by the user from the keypad unless programmed otherwise. Each system's group scan list is retained in memory when the radio is turned OFF. The Orion mobile radio may also be programmed to provide Trunked Priority Group Scan capability which operates similar to priority scan in Conventional mode.

The following is a description of PC-Programmable scan features that should be helpful in understanding the Group Scan Operation of the radio:

Scan Hang Time - the delay time the radio waits before resuming scan after the push-to-talk is released or after the carrier has dropped a channel.

TX Select - the group the radio will transmit on while scanning. The radio is programmed to transmit on either the scanned group or the selected group.

Scan List (privileges) - this feature allows or prohibits scan list changes by the user.

P1 Programming - priority group programming is accomplished by one (and only one) of three methods:

1.From the keypad, where the Priority programming is not fixed and does not follow the selected channel.

2.Priority 1 group programming follows the selected channel.

3.Priority 1 group programming is fixed during PC Programming and cannot be changed by the user.

P1 Always Scan - determines if the Priority 1 Group will always be scanned, regardless of the scan state set by the user.
