The Whistler Group SC03 Manuel D’Utilisation

Maintenance

Keep the scanner dry; if it gets wet, wipe it dry 
immediately. Use and store the scanner only in 
normal temperature environments. Handle the 
scanner carefully; do not drop it. Keep the scanner 
away from dust and dirt, and wipe it with a damp 
cloth occasionally to keep it looking new.

Modifying or tampering with the scanner’s 
internal components can cause a malfunction and 
might invalidate its warranty and void your FCC 
authorization to operate it.

Birdie Frequencies

Birdies are operating frequencies, which all scanners 
have, that are created inside the scanner’s receiver 
and can cause interference. If the interference is not 
severe, adjusting the squelch might omit the birdie, but 
if you program one of these frequencies after a search 
you will hear only noise on that frequency. 
To find birdies in your scanner:

1.  Disconnecting the antenna. 
2.  Make sure that no other nearby radio or TV sets 

are turned on near the scanner. 

3.  Press TUNE and then press PSE. The scanner 

will search for frequencies and occasionally stop 
as if it has found a signal. This is a birdie. 

4.  Make a list of all the birdies in your scanner for 

future reference.

5.  Press L/OUT to lock out the frequency for any 

future searches after you have reconnected the 
antenna.
