Ten Channel-Storage Banks — let you store 30 chan- nels in each bank to group channels so you can more easily identify calls.

Five Scan Lists — let you store up to 50 IDs in each tracking bank (up to a total of 500).

Two-Second Scan Delay — delays scanning for about 2 seconds before moving to another channel, so you can hear more replies that are made on the same channel.

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

Priority Channels — lets you program one channel in each bank (10 in all) and then have the scanner check it every 2 seconds so you don't miss transmissions on those channels.

Five Service-Search Banks — lets you search preset frequencies in separate police, fire/emergency, aircraft, marine, and weather banks, to make it easy to locate specific types of calls.

HyperSearch™ and HyperScan™ — lets you set the scanner to search at up to 300 steps per second and scan at up to 100 frequencies per second in frequency bands with 5 kHz steps, to help you quickly find interest- ing broadcasts. 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 searches. This lets the scanner avoid non-voice signals, making a search faster.

Key Lock — lets you lock the scanner's keys to help prevent accidental changes to the scanner's program- ming.

Manual Access — lets you directly access any channel.

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

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