The scanner’s frequency bands let you search specific, preset ranges of fre- quencies quickly and easily.

Your scanner has all these special fea- tures:

Weather Alert — warns you of serious weather conditions by sounding an alarm if the weather service transmits a weather alert tone.

Weather Band Key — scans seven pre- programmed weather channels to keep you informed about current weather conditions.

Scanner Control Protocol — lets you download channel information (frequen- cy, lockout, priority, delay) from your PC to the scanner.

Ten 20-Channel Storage Banks — let you store 20 channels in each of ten banks to group channels so calls are easier to identify.

Ten Monitor Memories — let you tem- porarily save ten frequencies located during a frequency search, so you can decide if you want to store them perma- nently.

Priority Channels — let you set the scanner to check up to ten channels ev- ery 2 seconds so you do not miss impor- tant calls.

Band Search — lets you quickly and easily search preset frequency ranges, so you can find new and unlisted broad- casts.

Direct Search — lets you search for a transmission starting from a specified frequency.

Search Skip — lets you select up to 20 frequencies for the scanner to skip dur- ing a search, so you can search more efficiently.

Two-Second Channel Scan/Search Delay — lets you set the scanner so it delays scanning or searching for 2 sec- onds before moving to another channel/ frequency, so you can hear more re- plies.

Lock-Out— keeps channels you select from being scanned, so you can skip over busy channels such as those with a continuous transmission.
