1. VOL/POWER

Power ON-OFF switch and volume control are combined.

Turning the control fully counter clockwise

will turn the

power OFF.

Clockwise rotation will increase the volume.

In the power OFF position, about 2.5mA current is drawn to

back-up the micro-computer and about 6maA of leakage cur-

rent for final module, provided the power cable is connected

to a constant power source.

To completely disable the transceiver, disconnect the power

cable.

2. SQUELCH

nal time.

Normally, this control is adjusted clockwise until

the

noise

disappears

and

the

goes

off

(threshold level).

For scan operation, this control must be

set to the threshold point.

3. TX Shift Indicator

+ (RED):
