Notes:

If the scanner picks up unwanted, partial, or very weak trans- missions, turn SQUELCH MIN/MAX clockwise to decrease the scanner’s sensitivity to these signals. If you want to listen to a weak or distant station, turn SQUELCH MIN/MAX counter- clockwise.

If SQUELCH MIN/MAX is adjusted so you always hear a hiss- ing sound, the scanner does not scan properly.

SEARCHING FOR AND STORING ACTIVE FREQUENCIES

You can store up to 100 frequencies into your scanner’s channels using either of the following methods.

Limit search within a range of preprogrammed frequencies

Manual storage

Good references for active frequencies are Radio Shack’s “Be- yond Police Call,” “Police Call Radio Guide Including Fire and Emergency Services,” “Aeronautical Frequency Directory,” and “Radio!” magazine. We update these references often, so be sure to get a current copy. See also “A General Guide to Scanning” on Page 39.

If you do not have a reference to frequencies in your area, follow the steps in “Limit Search” on Page 22 to search for transmis- sions.
