INTRODUCTION

Your new RadioShack PRO-70 50-Channel Portable Scanner lets you in on all the action. This scanner gives you direct access to over 22,000 exciting frequencies, in- cluding police and fire departments, ambulance services, and amateur radio services. You can select up to 50 chan- nels 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 also 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.

Two-Second Automatic Scan Delay — delays scanning for 2 seconds before moving to another channel, so you can hear more replies.

50 Channels — let you store up to 50 of your favorite fre- quencies for easy recall and scanning.

Monitor Memory — lets you temporarily save an active frequency you locate during a direct search, until you de- cide whether or not you want to save it into a channel.

Memory Backup — keeps the channel frequencies stored in memory for about 1 hour during a power loss.
