EXTERNAL SPEAKER

The external speaker jack (EXT.SPK) 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.

FRONT PANEL

OFF/ON/VOLUME (inner dual concentric). Turn clockwise to apply power

to the unit and to set the desired listening level. During normal operation, the

VOLUME control is used to adjust the output level obtained either at the

transceiver speaker or the external speaker, if used.

SQUELCH (outer dual concentric). 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 backgrounds noise is

eliminated. Turn fully counterclockwise then slowly clockwise until the

receiver noise disappears. Any signal to be received must now be slightly

stronger than the average received 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.

MIC GAIN (inner dual concentric). Adjust the microphone gain in the

transmit and PA modes. This controls the gain to the extent that full talk power

is available several inches away from the microphone.
