Radio Shack 20-422 Operation, Resetting Scanner, Manually Storing Frequencies Into Channels

OPERATION

TURNING ON THE SCANNER/SETTING VOLUME AND SQUELCH

1.Turn VOLUME and SQUELCH fully counterclockwise.

2.Turn VOLUME clockwise until you hear a hissing sound.

3.Turn SQUELCH clockwise, then leave it set to a point just after the hissing sound stops.

Notes:

•If the scanner picks up unwanted, partial, or very weak transmissions, turn SQUELCH clockwise to decrease the scanner’s sensitivity to these signals.

•If you want to listen to a weak or dis- tant station, turn SQUELCH counter- clockwise.

•If the scanner will not scan, turn SQUELCH further clockwise.

RESETTING THE

SCANNER

You might need to reset the scanner in any of the following conditions:

•before you use it for the first time (to clear anything that might already have been stored in memory previ- ously)

•if the scanner’s display locks up

•if the scanner does not work prop- erly after you connect power

•if the scanner is dropped or sub- jected to an electrical shock

Caution: This procedure clears all the information you have programmed into the scanner. Use this procedure only when you are sure your scanner is not working properly.

Follow these steps to reset the scanner.

1.Turn off the scanner.

2.While you hold down 2 and 9, turn on the scanner. When CLEAr appears, release 2 and 9.

MANUALLY STORING FREQUENCIES INTO CHANNELS

If you know of a frequency you want to store, you can manually store it into a channel.

Good references for active frequencies are RadioShack’s Police Call Radio Guide Including Fire and Emergency Services, Aeronautical Frequency Direc- tory, and Maritime Frequency Directory. We update these directories every year, so be sure to get a current copy. See also “Guide to the Action Bands” on Page 23 in this manual.

Note: If you do not have a reference to frequencies in your area, follow the steps in “Searching For and Temporarily Storing Active Frequencies” on Page 15 to search for transmissions.
