Troubleshooting

The scanner is not working at all.

•  The AC or DC adapter might not be connected. Be 

sure the adapter’s barrel plug is fully inserted into 
the 

PWR DC 9V

 jack. The center tip of the adapter’s 

barrel plug must be set to positive.

•  The batteries might be dead or need to be 

recharged. Recharge the rechargeable batteries or 
replace the alkaline batteries.

The scanner does not receive any stations or 
reception is poor. 

•  An antenna is not connected or is connected 

incorrectly. Be sure an antenna is properly 
connected to the scanner.

The scanner is on but does not scan. 

•  The squelch might not be adjusted correctly. Turn 

SQUELCH

 clockwise. 

•  Only one channel or no channels are stored. Store 

frequencies into more than one channel.

The keypad does not work. 

•  Keylock is turned on. Turn off keylock by holding 

down 

 / 

 for about three seconds

•  The scanner might need to be reset or initialized. 

Turn the scanner off then on again, or initialize the 
scanner (see 

“Initializing the Scanner” 

on page 33).

While scanning, the scanner locks on frequencies 
that have an unclear transmission.

•  Some frequencies programmed into the scanner 

might be the same as birdie frequencies. Avoid 
programming birdie frequencies or only listen to 
them manually.

Birdie Frequencies

Every scanner has birdie frequencies. Birdies are signals 
created inside the scanner’s receiver, which may interfere 
with transmissions on the same frequencies. If you 
program one of these frequencies, you hear only noise 
on that frequency. If the interference is not severe, you 
might be able to turn Squelch clockwise to omit the 
birdie. 

To find the birdies in your scanner, disconnect the 
antenna and move it away from the scanner. Make sure 
that no other nearby radio or TV sets are turned on near 
the scanner. Use the Tune to search every frequency 
range from its lowest frequency to the highest. 
Occasionally, the searching will stop as if it has found a 
signal, often without any sound. This is a birdie. Make a 
list of all the birdies in your scanner for future reference.
