Engine Noise Suppression

Interference from the noise generated by the electrical systems of engines is sometimes a problem with radios. Your radio has been
designed to be essentially impervious to ignition noise and alternator noise. However, in some installations it may be necessary to
take measures to further reduce the effect of noise interference. Your radio' s DC battery wires, antenna lead, and accessory cables
should be routed away from the engine and engine compartment, and from power cabling carrying high currents. In severe cases of
noise interference, it may be necessary to install a noise suppression kit. Contact the dealer where you purchased the radio for more
information.
