Radio Shack PRO-91 - Manual (Page 3)

3
Five Channel-Storage Banks — you can store up to
30 channels in each of 5 different banks to group chan-
nels so you can more easily identify calls.
Five Scan Lists — you can store up to 50 trunking IDs
in each trunk tracking bank.
Two-Second Scan Delay — delays scanning for about
2 seconds before moving to another channel, so you
can hear more replies that are made on the same chan-
nel.
Lock-Out Function — lets you set your scanner to skip
over specified channels or frequencies when scanning
or searching, and skip over IDs when tracking trunked
systems.
Priority Channels — lets you program one channel in
each bank (5 in all) and then have the scanner check
that channel every 2 seconds while it scans the bank,
so you don't miss transmissions on those channels.
Five Service Banks — frequencies are preset in sepa-
rate police (fire/emergency), aircraft, ham, marine, and
weather banks, to make it easy to locate specific types
of calls.
Hypersearch

— lets you set the scanner to search at
up to 300 steps per second. The normal search speed
is 100 steps per second.
Hyperscan

— the scanner automatically scans up to
50 channels per second in frequency bands with 5 kHz
steps, to help you quickly find interesting broadcasts.
Key Lock — lets you lock the scanner's keys to help
prevent accidental changes to the scanner's program-
ming.
Data Signal Skip — lets you set the scanner to skip
non-modulated or data signals (such as fax or modem
transmissions) during searches. This lets the scanner
avoid non-voice signals, making a search faster.
Manual Access — lets you directly access any channel.
Liquid-Crystal Display — makes it easy to view and
change programming information.
Display Backlight — makes the scanner easy to read
in low-light situations.
