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 warranty
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 following
correct procedure and that the radio was properly installed, etc.
