FCC INFORMATION

The Federal Communications Commission (FCC) does not 
require you to have a license to operate this CB. However, 
the FCC does require that you read and know Part 95 of 
FCC Rules. These rules apply to the operation of a Class D 
CB. 

Warning: Do not open your CB to make any internal 
adjustments. Any internal adjustments can be made only by 
an authorized service technician.

Unauthorized internal adjustments and/or modifications can 
lead to illegal operation as defined by Part 95 of FCC Rules. 
Such illegal operation can lead to very serious 
consequences.

Your CB might cause TV or radio interference even when it 
is operating properly. To determine whether your CB is 
causing the interference, turn off your CB. If the interference 
goes away, your CB is causing it. Try to eliminate the 
interference by:

• moving your CB away from the receiver

• connecting your CB to an outlet that is on a different 

electrical circuit from the receiver

• contacting your local RadioShack store for help

If you cannot eliminate the interference, the FCC requires 
that you stop using your CB.

This device complies with Part 15 of the FCC Rules. 
Operation is subject to the following two conditions: (1) this 
device may not cause harmful interference, and (2) this 
device must accept any interference received, including 
interference that may cause undesired operation.
