Setting the Squelch
Note: Make sure the scanner's antenna is connected

Scanning Systems
To begin scanning programmed systems, press Scan.
The SC230 scans all unlocked systems in all activated
quick-key groups.
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.
