Introduction
Thank you for purchasing the RadioShack
200-Channel VHF/AIR/UHF Desktop
Scanner. This scanner gives you direct
access to over 25,000 frequencies, including
those used by police and fire departments,
ambulance services, government agencies,
air, and amateur radio services. You can
select up to 200 channels to scan, and you
can change your selection at any time.
The secret to your scanner's ability to scan
so many frequencies is its built-in
microprocessor. Your scanner also has
these special features:
Four Service Banks
— let you search
preset frequencies in separate fire/police, air,
ham radio, and marine banks, to make it
easy to locate specific types of calls.
Two-Second Scan Delay
— delays
scanning for 2 seconds before moving to
another channel, so you can hear more
replies.
Ten Channel-Storage Banks
— let you
store up to 20 channels in each of 10
different banks, to group channels so you
can more easily identify calls.
20 Monitor Memories
— let you temporarily
save up to 20 frequencies you locate during
a search, so you can move selected
frequencies to channel storage later.
Memory Backup
— keeps the channel
frequencies stored in memory for about 1
hour during a power loss.
HyperSearch
TM
and
HyperScan
TM
— let
you set the scanner to search at up to 50
steps per second and to scan at up to 25
channels per second, to help quickly find
interesting transmissions.
Duplicate Frequency Check
automatically notifies you if you are about to
store a frequency you have already stored,
to help avoid wasting storage space.
Direct Search
— lets you search for new
and unlisted frequencies starting from a
specified frequency.
Priority Channel
— lets you program a
frequency in the priority channel to be
scanned every 2 seconds so you do not miss
important calls.
Weather Band (WX) Key
— scans seven
preprogrammed weather frequencies to keep
you informed about current weather
conditions.
Weather Alert
— automatically sounds the
alarm tone to advise of hazardous weather
conditions when the scanner detects an alert
signal on the local NOAA weather channel.
Lock-Out Function
— lets you set your
scanner to skip over specified channels or
frequencies when scanning or searching.
Liquid Crystal Display
— makes it easy to
view and change programming information
at any time.
Display Backlight
— makes the scanner
easy to read in low light situations.
Supplied Telescoping Antenna
— lets the
scanner receive strong local signals.
External Antenna Terminal
— lets you
connect an external antenna (not supplied)
to the scanner.
