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.
