POWER REQUIREMENTS
The transceiver is supplied ready to operate from any regulated 13.8V DC, 3.5 ampere negative
ground source. An automobile 12 volt, negative ground, system is usually more than adequate.
Some note must be taken, however, of the condition of the vehicle's electrical system. Items such
as low battery, worn generator/alternator, poor voltage regulator, etc., will impair operation of
your transceiver as well as the vehicle. High noise generation ог low voltage delivery can be traced
to these deficiencies. If an AC power supply is used with your transceiver, make certain it is
adequately regulated for both voltage and current. Low voltage while under load will not produce
satisfactory results from your transceiver. Receiver gain and transmitter output will be greatly
impaired. Caution against catastrophic failure of the power supply should be observed.
Included with your transceiver is a DC power cable with plug attached. The Red Wire is positive
(+), the Black, negative (—). If your mobile installation permits, it is best to connect these directly
to the battery terminals. This arrangement eliminates random noise and transient spikes some-
times found springing from automotive accessory wiring. If such an arrangement is not possible,
then any convenient B+ lead in the interior of the vehicle and the negative frame can be utilized.
Remember, the unit operates on a negative ground system only; it cannot be used in a positive
ground automobile. After making your connections, simply insert the plug into your transceiver.
