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.
