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.
