ASTRO XTL 5000 Digital Mobile Radio with O5 Control Head 23
General Radio Features
Scan Operation
The scan feature allows you to monitor activity on different 
conventional or trunked modes by scanning a scan list of modes. The 
modes to be scanned in a scan list are programmed by a qualified 
radio technician. You can select the modes to be scanned in a scan 
list if operator-selectable scan is enabled.
There are three types of scan lists available:
• Conventional—Comprises up to 15 different conventional-only 
modes
• Trunked Priority Monitor—Comprises up to 15 modes that are all 
from the same trunked system
• Talkgroup Scan—Comprises up to 10 combined conventional 
modes and modes from one trunking system
The radio supports both priority and non-priority scanning. With 
priority scanning enabled, a scan list can have one mode assigned as 
the first-priority mode and a second as the second-priority mode.
The XTL 5000 Digital Mobile Radio supports automatic scanning 
(autoscan), which can be programmed into the radio by a qualified 
radio technician. With this feature, the radio begins scanning 
whenever you select a mode to which a scan list is assigned.
Note: You cannot turn scan off on a mode that has autoscan 
enabled.
If multiple scan types are enabled in the radio, the type of scan that is 
activated depends on the personality of the mode selected when the 
SCAN softkey is pressed. For all types of scan, the selected mode is, 
by default, a member of its own scan list.
Scan lists stay in memory when you turn scan off, turn the radio off, or 
disconnect the radio from the battery.
