Basic Operation

Turning On the Scanner and

Setting the Squelch

Note: Make sure the scanner's antenna is connected
before you turn it on.
1. Turn Sql fully counterclockwise.
2. Press and hold for about 2 seconds to turn on the
scanner, then turn Vol clockwise until you hear a
hissing sound.
3. Turn Sql clockwise until the hissing stops.

Scanning Systems

To begin scanning programmed systems, press Scan.
The USC230 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 USC230 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 USC230 scans a system for the duration you set
using the System Hold Time option (see “Setting the
System Hold Time” on Page 55). All unlocked
channels are scanned at least one time regardless of
the hold time setting.
