FEATURES

Your new RadioShack PRO-72 50-Channel Portable Scanner gives you direct access to over 32,000 exciting frequencies, including police and fire departments, ambu- lance services, and amateur radio services. You can se- lect up to 50 channels to scan, and you can change your selection at any time.

The secret to your scanner’s ability to scan so many fre- quencies is its custom-designed microprocessor — a tiny, built-in computer.

Your scanner has these special features:

Ten Preprogrammed Search Bands — let you search for transmissions within preset frequency ranges, so you can find interesting frequencies more quickly.

Ten Preprogrammed Weather Frequencies — keep

you informed about current weather conditions.

HyperScanand HyperSearchso you can scan up to 25 channels per second and search up to 50 steps per second.

Fifty Channels — let you store up to 50 of your favorite frequencies for easy recall and scanning.

Duplicate Frequency Check — automatically warns you if you try to store a frequency you’ve already stored, to help you use the scanner’s memory more efficiently.

Monitor Memory — lets you temporarily save a frequen- cy located during a direct search, so you can move it to channel storage later.
