Maintenance and Adjustment
Your COBRA CB transceiver is specifically designed for
the environment encountered in mobile installations.
The use of all solid state circuitry and its light weight
result in high reliability. Should a failure occur,
however, review the following, then if necessary,
replace parts only with identical parts. Do not
substitute.
Check connections to the source of power and
make sure it is the 13.8 VDC required to operate
your radio.
Check the fuses in the DC power cord. The main
power lead (red ) has a 2 amp 3AG type fuse in its
holder. Use only the above specified type and size
fuse for maximum protection. Failure to do so will
void the warranty.
Make certain the microphone is properly
plugged in.
Make certain the antenna is properly assembled
and connected.
If you are unable to correct the problem, refer to the
SERVICE INSTRUCTIONS at the end of this manual for
the correct procedure for warranty and post-warranty
service from COBRA.
