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.
