Maintenance and Adjustment, Appendix | Cobra Electronics 19 DX II

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. Refer to the schematic diagram and parts list.

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 3 AG type fuse installed. 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 for tuning 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 him.

If you are unable to correct the problem, please contact your local dealer.

Adjustment Warning

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