Ignition Noise Interference
Use of a CB receiver at low signal levels is normally limited by the presence of electrical noise.
Under most operating conditions, when signal level is adequate, the background noise does not
present a serious problem. Also, when extremely low level signals are being received, the transceiver
may be operated with vehicle engine turned off. The unit requires very little current and therefore
will not significantly discharge the vehicle battery.
Even though this radio has an automatic noise limiter, in some installations ignition interference
may be high enough to make good communications impossible. Consult your authorized Cobra
dealer or a two-way radio technician for help in locating and correcting the source of severe noise.
Maintenance/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.
Check Power Source
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 fuses in the DC power cord.
Check Fuses in DC Power Cord
The main power lead (red) has a two 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.
