low level signals are being received, the transceiver may be
operated with vehicle engine turned off. The unit requires
very little current an therefore will not signicantly discharge
the vehicle battery.
Even though the supernova radio has an automatic noise
limiter, in some installations, ignition interference and other
forms of automobile generated noise may be high enough
to make good communications difcult. The electrical noise
may come from several sources. Many possibilities exist
and variations between vehicles require different solutions
to reduce the noise. Consult your supernova dealer or a
2-way radio technician for help in locating and correcting
the source of severe noise.
Temporary Mobile Operations
To operate your supernova transceiver from a car on a
temporary basis, you may want to purchase an optional cigar
lighter adapter from your supernova dealer. This adapter and
a magnetic mount antenna allow you to quickly „install” your
transceiver for temporary use.
Operation
Front Panel
1. Off/On/Volume. Turn clockwise to turn power on and
set the desired listening volume.
2. Squelch. This control is used to cut off or eliminate
receiver background noise in the absence of an incoming
signal. For maximum receiver sensitivity, it is desired that
the control be adjusted only to the point where the receiver
background noise or ambient background noise is eliminated.
Adjust until the receiver noise disappears. This will require
the incoming signal to be slightly stronger than the average
receiver noise. Further clockwise rotation will increase the
threshold level which a signal must overcome in order to
be heard. Only strong signals will be heard at a maximum
clockwise setting.
3. Microphone Connector. This front mounted, screw-on
connector allows for convenient removal of the microphone
plug when storage is required. The microphone MUST be
connected to the unit at all times when in use, for proper
operation. The screw-on connection enhances the life of
the microphone cord as well.
4. Channel 9/Normal Switch. Used for instant selection
of emergency channel 9 (CH.9 position). In NOR position,
all 40 CB channels are selected by the UP/DOWN CHAN-
NEL BUTTONS.
