SYSTEM AND GROUP SCANNING

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.
