Maintenance and Adjustment

Your COBRA CB transceiver is specifically designed for the environ-
ment encountered in mobile installations. The use of all solid state cir-
cuitry 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 dia-
gram 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 spec-
ified 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 mini-
mum SWR. NOTE: COBRA antennas include full instructions for
tuning your antenna. If youÕre 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, refer to the WARRANTY SER-
VICE INSTRUCTIONS at the end of this manual for the correct proce-
dure for warranty and post-warranty service from COBRA.
Replacement or substitution of certain parts with replacements other
than those recommended by Cobra Electronics, may be a violation of the
technical regulations of Part 95 of the FCC Rules, or the 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.
