Operation Ignition Noise Interference Note When using the unit with cigarette adapter, turn off when not in use to avoid draining the battery. Temporary Mobile Operation Note Red and Orange wires are connected to positive side of socket center tip. Black wire is connected to negative side contacts. Note Radio resets to CH 9 when connected to cigarette lighter plug. Ignition Noise Interference Use of a mobile 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 COBRA dealer or a 2-way radio technician for help in locating and correcting the source of severe noise. Temporary Mobile Operation For temporary mobile operation, you may want to purchase an additional cigarette lighter adapter from your COBRA dealer.This adapter and a magnetic mount antenna allow you to quickly "install" your transceiver for temporary use.
