Scan Delay — delays scanning for about 2 seconds before moving to an- other channel in conventional mode, so you can hear more replies that are made on the same channel. In trunk tracking mode, it delays for about 5 seconds before moving to another ID.

Lock-Out Function — lets you set your scanner to skip over specified channels or frequencies when scan- ning or searching, and skip over IDs when tracking trunked systems.

Priority Channels — lets you pro- gram one channel in each bank (10 in all). As the scanner scans a bank, it checks the bank’s priority channel ev- ery 2 seconds so you don't miss trans- missions on that channel.

Five Service-Search Banks — lets you search preset frequencies in sep- arate public service, police, fire/emer- gency, aircraft, and weather banks, to make it easy to locate specific types of calls.

HyperSearchand HyperScan— let you set the scanner to search at up to 300 steps per second (in frequency bands with 5 kHz steps) and scan at up to 50 channels per second, to help you quickly find interesting broad- casts. (The normal search speed is 100 steps per second).

Data Signal Skip — lets you set the scanner to skip non-modulated or data signals during scanning and searches. This lets the scanner avoid non-voice

signals, making a scan or search fast- er.

Manual Access — lets you directly access any stored channel.

Liquid-Crystal Display — makes it easy to view and change program- ming information.

Display Backlight — makes the scanner easy to read in low-light situa- tions.

Supplied Telescoping Antenna — provides good reception of strong lo- cal signals.

External Antenna Terminal — lets you connect an external antenna with a BNC connector to the scanner for improved reception of distant/weaker signals.

Memory Backup — keeps the chan- nel frequencies stored in memory for an extended time.

Key Confirmation Tones — the scanner sounds a tone when you per- form an operation correctly, and an er- ror tone if you make an error.

Duplicate Channel Alert — warns you when the frequency you are stor- ing already exists in memory.
