Ignition Noise Interference
Use of a mobile receiver at low signal levels is nor-
mally 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 lim-
iter, 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 mag-
netic mount antenna allow you to quickly "install"
your transceiver for temporary use.
