Scan Delay — delays scanning for
about 2 seconds before moving to an-
other channel in conventional mode,
so you can hear more replies that are
made on the same channel. In trunk
tracking mode, it delays for about 5
seconds before moving to another ID.
Lock-Out Function — lets you set
your scanner to skip over specified
channels or frequencies when scan-
ning or searching, and skip over IDs
when tracking trunked systems.
Priority Channels — lets you pro-
gram one channel in each bank (10 in
all). As the scanner scans a bank, it
checks the bank’s priority channel ev-
ery 2 seconds so you don't miss trans-
missions on that channel.
Five Service-Search Banks — lets
you search preset frequencies in sep-
arate public service, police, fire/emer-
gency, aircraft, and weather banks, to
make it easy to locate specific types of
calls.

and HyperScan

—
let you set the scanner to search at up
to 300 steps per second (in frequency
bands with 5 kHz steps) and scan at
up to 50 channels per second, to help
you quickly find interesting broad-
casts. (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 scanning and searches.
This lets the scanner avoid non-voice
signals, making a scan or search fast-
er.
Manual Access — lets you directly
access any stored channel.
Liquid-Crystal Display — makes it
easy to view and change program-
ming information.
Display Backlight — makes the
scanner easy to read in low-light situa-
tions.
Supplied Telescoping Antenna —
provides good reception of strong lo-
cal signals.
External Antenna Terminal — lets
you connect an external antenna with
a BNC connector to the scanner for
improved reception of distant/weaker
signals.
Memory Backup — keeps the chan-
nel frequencies stored in memory for
an extended time.
Key Confirmation Tones — the
scanner sounds a tone when you per-
form an operation correctly, and an er-
ror tone if you make an error.
Duplicate Channel Alert — warns
you when the frequency you are stor-
ing already exists in memory.
