Scanning Systems
To begin scanning programmed systems, press Scan. The SC230 scans all unlocked systems in all activated
Notes:
•If no systems are programmed, or all systems are locked out, an error message appears. Program a system or select a system to scan.
•When scanning multiple systems, the SC230 scans systems according to the assigned quick key.
Then the race assigned to the next quick key (1, 2, 3, 4, etc.) is scanned. Systems not assigned to a quick key are scanned last. Within a quick key, systems are scanned in the order they were assigned.
•Within a system, channels are scanned according to the assigned channel group, with the same priority as described above for systems.
•The SC230 scans a system for the duration you set using the System Hold Time option (see “Setting the System Hold Time” on Page 56). All unlocked chan- nels are scanned at least one time regardless of the hold time setting.
