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.
HyperSearch 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.
