Turning On The Scanner; Setting The Battery Type; Understanding The Display Icons - Radio Shack PRO-651 User Manual

Turning on the Scanner

The squelch and attenuator control scanner
sensitivity. If squelch is set too low, the scanner may
stop on noise or silence.
Note: Make sure the scanner's antenna is connected
before you turn it on.
1. Turn the SQUELCH knob to about mid-position.
2. Turn the VOLUME knob to turn on the radio.
3. Turn SQUELCH down (counterclockwise) until
you hear noise.
4. Turn SQUELCH up (clockwise) a little past where
the noise stops. The higher the squelch is set,
the stronger the signal required to break the
squelch.

Setting the Battery Type

Setting the battery type is necessary for low battery
detection and to enable battery charging. By default,
your new scanner is configured to use alkaline
batteries.
If you are using rechargeable batteries:
1. Press the PGM key.
2. Press the GLOB softkey.
3. Use the 4-direction keypad to select the
Battery setting and set your battery type.
4. Press the SAVE softkey.
