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.

Basic Operation
Scanning Preprogrammed Races
Before You Get To The Track
Each driver’s team has several different frequencies they 
can use during a race. These frequencies can change 
depending on local interference sources or other 
frequency issues. Your scanner is preprogrammed with 
all of the drivers and their possible frequencies that were 
known when it was manufactured.
Before you leave for the track, check the Internet to see if 
there are any frequency updates available for your race. 
You can save time at the track by setting up as much as 
possible before you leave.
When You Get To The Track
When you arrive at the race, get a list of the actual fre-
quencies in use that race day. These are normally avail-
able for sale on the way into the facility. This list will show 
the actual frequency being used by each driver that day, 
as well as some other useful frequency information. 
Then, follow the steps in the sections below to adjust the 
scanner settings.
Selecting Driver Frequencies
Follow these steps to select the appropriate frequency for 
each driver.
1. Press 0, rotate the scroll control to select the race, 
then press E.
2. Press CAR, enter the driver’s number, press E or 
CAR, press E,  rotate the scroll control to select the 
driver, then press E.
3. Rotate the scroll control to select the driver’s 
frequency. If the driver’s frequency is not listed, select 
NEW Frequency then enter the correct frequency.
4. Press Hold to set the selection.

Basic Operation Selecting Interference Eliminator Codes
Many drivers use special codes in their radios to prevent 
interference from other nearby radio systems. These 
codes are commonly referred to as CTCSS, DCS, or 
subaudible tones. You can use these same codes to 
prevent interference from other systems.
1. Press 0, rotate the scroll control to select the race, 
then press E.
2. Press CAR, enter the driver’s number, press E or 
CAR, press E,  rotate the scroll control to select the 
driver, then press E.
3. Rotate the scroll control to select the driver’s 
frequency, then press E. 
4. Press E to enter the channel setting menu.
5. Rotate the scroll control to select SET CTCSS/DCS, then 
press E.
6. Enter the correct CTCSS/DCS value, then press E. 
7. Press Hold to set the selection 
Selecting Systems to Scan

system(s), press Scan again.
The SYS indicators on the display show the systems that 
are currently selected.
To select or lock out a system that is not assigned to a 
key, press and hold   while you rotate the scroll
