List type system scan
A scan list can be set for each system.
The list to be scanned can be changed by changing the
display system
If many system have been set, the scan speed can be
increased by narrowing the systems to be scanned with scan
lists.
2) System lockout
The system lockout feature is used to lock systems out of
the scan sequence, and can be selected by programming in
the following two ways:
Fixed lockout
The system to be locked out is selected by programming.
When a locked system is selected, the Delete ( ) indicator
appears on the left of the SYSTEM indicator. The revert system
is scanned even if it is locked out. If there is a locked system,
the Delete ( ) indicator flashes during fixed scanning.
User selectable lockout
If the scan lockout feature is programmed to a key, the user
can lock systems out of the scan sequence with the key. To
lock a system out of the scan sequence, press the key when
the system is displayed. The Delete ( ) indicator is displayed
on the left of the SYSTEM indicator.
To unlock a system, select the system and press the key.
The Delete ( ) indicator disappears to indicate that the system
has returned to the scan sequence. The revert system is
scanned even if it is locked out. If there a locked system, the
Delete ( ) indicator flashes during fixed scanning. If all systems
are locked out, the scan stops and only the revert system is
received.
3) Drop-out delay time (Scan resume time)
If a call is received during scan, the scan stops. The scan
resume time can be programmed as 0 to 300 seconds in one-
second increments. The default value is 3 seconds.
4) Dwell time
The dwell time is the time after transmission ends until the
scan resumes in scan mode. It can be set 0 to 300 seconds by
programming. The default value is 3 seconds.
5) System/Group revert
System/Group revert can be programmed for one of the
following;
Last called revert
The system/group changes to the revert system or group
when a call is received with the system/group being scanned.

6) Scan message wait
signal during system scan and monitoring data messages can
be programmed. If there is no signal from the home repeater,
the system is scanned for about 50ms. If there is a signal,
three data messages are monitored. Normally, three data
messages are monitored for each system, and it can be
increased in multiples of three data messages per line to up to
eight lines.
data monitoring is terminated and the home repeater of the
next system is scanned.
7) Group scan operation

other groups that are permitted for group scan are decoded.
