SYSTEM AND GROUP SCANNING
37
Scan Types
The type of scanning selected is determined by the menu mode
SCN TYPE parameter (see page 33). If it is not selectable, the type
of scanning is fixed by programming. The available scan types are as
follows.
SYSTEMS - Both system and group
GROUPS - Group scanning only
OFF - Both types disabled (SCAN switch non-functional)
If the SCAN option switch is not programmed, the selected
mode is always enabled. If both the switch and SCN TYPE menu
parameter are disabled, the scan mode and type are fixed by
programming. The selected system and group can be changed while
scanning using the Select switch in the normal manner. Scanning
resumes shortly after the change is made.
When a call is received in the scan mode, the display changes to
the system and group of the call. Programming determines if this
change is temporary or permanent, and if a response occurs on the
system/group of the call or the selected system/group. Refer to
“Transmitting In The Scan Mode” on page 39 for more information.
LTR-Net Mode Scanning
When system scanning with an LTR-Net system selected and
roaming disabled, only the LTR-Net systems in the scan list that
access the site of the selected system are scanned. LTR and conven-
tional systems are not scanned.
When system scanning with roaming enabled, registration on
other sites occurs normally and scanning operates as just described.
However, if the current LTR-Net site is lost and no other LTR-Net
site can be located, the LTR and conventional systems in the scan list
are also scanned. If an LTR-Net site is again detected, registration on
that site occurs and the LTR and conventional systems are no longer
scanned. This can provide uninterrupted operation in areas which
have not been converted to LTR-Net operation.
