of electrical noise. Under most operating conditions, when signal level is adequate,
the background noise does not present a serious problem. Also, when extremely Secondary Icons
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.
Notice Caution
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 two­way radio technician
for help in locating and correcting the source of severe noise.
