Maintenance and Adjustment

Your COBRA CB transceiver is specifically designed for the environment encountered in mobile installations. The use of all solid state cir- cuitry and its light weight result in high reliabili- ty. Should a failure occur, however, review the fol- lowing, then if necessary, replace parts only with identical parts. Do not substitute.

1.Check connections to the source of power and make sure it is the 13.8 VDC required to oper- ate your radio.

2.Check the fuses in the DC power cord. The main power lead (red & orange wire) has a 2 amp 3AG type fuse in its holder. Use only the above specified type and size fuse for maxi- mum protection. Failure to do so, will void the warranty.

3.Make certain the microphone is properly plugged in.

4.Make certain the antenna is properly assem- bled 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.
