Hypersearch— lets you set the scanner to search at up to 300 steps per second, to help you quickly find interesting broadcasts. (The nor- mal search speed is 100 steps per second).

Two-Second Scan Delay — automatically delays scanning for about 2 seconds before moving to another channel, so you can hear more re- plies.

Lock-Out Function — lets you set your scanner to skip over specified channels.

Direct Frequency Search — lets you search all frequencies, starting directly from a specified frequency.

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.

Search Skip — lets you set the scanner to skip up to 20 frequencies you select during searches. This lets the scanner avoid unwanted sig- nals.

Three Power Options — let you power the scanner using alkaline or rechargeable nickel-cadmium batteries, external AC power using an optional AC adapter/charger, or DC power using an optional DC adapter.

Memory Backup — keeps the frequencies stored in memory for up to 3 days if the PRO-74 loses power.

Key Confirmation Tones — the scanner sounds a tone when you per- form an operation correctly, and an error tone if you make an invalid entry. You can turn the key confirmation tones on or off.

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

Battery Low Alert — warns you when battery power gets low.

Battery Save — saves battery power when the scanner does not de- tect any transmissions for more than 5 seconds while a channel is manually selected or while you are programming the scanner.

Key Lock — lets you lock the scanner's keys to help prevent acciden- tal changes to the scanner's programming.
