IGNITION NOISE INTERFERENCE

With weak signals, you may experience interference of the signal by background

noise. This radio has NB and ANL circuits which will help reduce background noise

from sources such as your ignition system. However, background electrical noise may

come from several sources and all noise may not be eliminated. With extremely weak

signals, you can operate this radio with the engine turned off, which should improve

reception. If the ignition noise level is too high to allow proper operation under most

conditions, you should have your installation of the radio checked by a qualified

technician.

ANTENNA

This radio has a jack in the rear for a standard PL-259 antenna plug. If you are

looking for the most range for your transmission, use a vertically polarized, quarter-

wave length antenna. If antenna height is a problem, you may use a shorter, loaded-type

whip antenna although you can expect some loss of transmission range.

To improve performance, your antenna should be matched to your radio. Your antenna

can be adjusted so that it matches your radio.

EXTERNAL SPEAKER

The external speaker jack (EXT SP.) on the rear panel is used for remote receiver

monitoring. The external speaker should have 8 ohms impedance and be able to handle

at least 4 watts. When the external speaker is plugged in, the internal speaker is

disconnected.

PUBLIC ADDRESS

To use the Public Address (PA) function, first connect an external speaker to the PA.

SP. Jack on the rear of the radio. See the above specifications for a proper external

speaker. Keep the speaker away from the microphone to avoid acoustic feedback.

1. MICROPHONE JACK: Used to connect microphone for voice source.

2. ON/OFF VOLUME CONTROL: This knob controls the volume and power to the

radio. To turn radio on, rotate the knob clockwise. Turning the knob further will

increase the volume of the receiver.

3. SQUELCH CONTROL: This knob is used to eliminate background noise being

heard through the receiver, which can be disturbing when no transmissions are

being heard through the receiver. To use this feature, turn the knob fully

counterclockwise and then turn clockwise slowly until the background noise is just

eliminated. 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.

4. MIC GAIN CONTROL: Adjusts the microphone gain in transmit and PA modes.

This controls the gain to the extent that full talk power is available several inches

away from the microphone. In the Public Address (PA) mode, the control functions

as the volume control.
