Maintenance and Adjustment

The COBRA CB transceiver is specifically designed for the environment encoun- tered 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. Refer to the schematic diagram and parts.

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

2.Check the fuse in the DC power cord. The main power lead (red wire) 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.

3.Make certain the microphone is properly plugged in.

4.Make certain the antenna is properly connected and tuned for minimum SWR. NOTE: COBRA antennas include full instructions as to how to tune your antenna. If you're still in doubt about the procedure, contact the COBRA dealer from whom you purchased your radio and antenna, for advice. If you hired an installer to install your radio and antenna, contact the installer.

If you are unable to correct the problem, refer the WARRANTY SERVICE INSTRUCTIONS at the end of this manual for the correct procedure for warran- ty and post-warranty service from COBRA.

Adjustment Warning

Replacement or substitution of certain parts with replacements other than those recommended by COBRA, may be a violation of the technical regulations of Part 95 of the FCC Rules, or of Type Acceptance requirements of Part 2 of said rules.

When making adjustments other than transmitter adjustments, be sure to re- read applicable portions of this instruction manual to make certain you are fol- lowing correct procedure and that the radio was properly installed, etc.
