SPECIFICATIONS
Specifications are typical unless otherwise indicated and may be subject to change
without notice or obligation.
NOISE SUPPRESSION
27 MHz CB radio can be prone to electrical
and ignition interference. The reason is that
electrical noise is a form of AM transmission
similar to that used by your radio and your
radio’s receiver is very sensitive. In most
cases, ignition noise can be greatly reduced
or eliminated by selecting the Noise Limiter
(NL) key on the radio. In some severe cases
additional suppression may need to be fitted
to the ignition system of your vehicle in
which case we recommend you consult an
auto electrician for advice specific to your
installation.
