Five Channel-Storage Banks — you can store up to 30 channels in each of 5 different banks to group chan- nels so you can more easily identify calls.

Five Scan Lists — you can store up to 50 trunking IDs in each trunk tracking bank.

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 chan- nel.

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 (5 in all) and then have the scanner check that channel every 2 seconds while it scans the bank, so you don't miss transmissions on those channels.

Five Service Banks — frequencies are preset in sepa- rate police (fire/emergency), aircraft, ham, marine, and weather banks, to make it easy to locate specific types of calls.

Hypersearch™ — lets you set the scanner to search at up to 300 steps per second. The normal search speed is 100 steps per second.

Hyperscan™ — the scanner automatically scans up to 50 channels per second in frequency bands with 5 kHz steps, to help you quickly find interesting broadcasts.

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

Data Signal Skip — lets you set the scanner to skip non-modulated or data signals (such as fax or modem transmissions) during searches. This lets the scanner avoid non-voice signals, making a search faster.

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.
