PRO-23 (200-0504) Features Faxback Doc. # 6487
The new Radio Shack PRO 23-50-Channel Direct Entry Programmable Scanner
lets you in on all the action! This scanner gives you direct access to
over 25,000 exciting frequencies that include the police department, fire
department, ambulance, amateur radio, and transportation services. You
can select up to 50 channels for your scanner to scan and you can change
your selection at any time.
The secret to the scanner's ability to scan so many frequencies is its
custom-designed microprocessor-a tiny, built-in computer. The scanner
also has these special features:
Two-Second Automatic Scan Delay - Delays the scanning mode for two
seconds before moving to another
channel, so you can hear more replies.
Memory Backup - Keeps the channel frequencies stored in
memory for up to 1 hour during power
loss.
Lock-Out Function - Keeps channels you select from being
scanned.
Priority Channel - Checks your most important channel
every 2 seconds so you don't miss
important calls on a channel you
specify.
Weather Band Key - Scans 7 preprogrammed weather
frequencies so you can hear about
current weather conditions.
Ten Channel-Storage Banks - Lets you store 10 channels in each
of 5 banks to group frequencies. This
lets you easily identify calls.
Monitor Memories - Lets you temporarily save up to 5
channels you locate during a frequency
search.
Display Backlight - Makes the scanner easy to read in
low light situations.
Frequency Search - Scans through every available
frequency.
The scanner can receive all of these bands:
108-136.975 MHz (aircraft)
137-144 MHz (government)
144-148 MHz (ham radio 2 m)
148-174 MHz (VHF Hi)
406-450 MHz (ham radio and government)
450-470 MHz (UHF Standard)
470-512 MHz (UHF "T" Band)
806-823.9375 MHz (Public Service)
851-868.9375 MHz (UHF Hi)
896.1125-956 MHz (UHF Hi)
In addition, the scanner is preprogrammed with the following weather
service channels:
162.400 MHz
162.425 MHz
162.450 MHz
162.475 MHz
162.500 MHz
162.525 MHz
162.550 MHz

SPECIAL FEATURES
USING THE KEYLOCK
Once you program your scanner, you can protect it from accidental program
changes by turning on the keylock feature. In this mode, the only
controls that operate are SCAN, MANUAL, KEYLOCK, VOLUME, and SQUELCH.
(However, KEYLOCK does not keep the scanner from continuing to scan
channels.)
To turn on the keylock, press and hold KEYLOCK until the scanner beeps
and KEYLOCK appears on the display. To turn it off, press and hold
KEYLOCK until the scanner beeps and KEYLOCK disappears from the display.
LOCKING OUT CHANNELS
You can increase the effective scanning speed by locking out channels
that you have not yet programmed, or channels that have a continuous
transmission, such as a weather channel. To lock out a channel, manually
select the channel and press lockout so L/O appears on the display.
To remove the lock-out from a channel, manually select the channel and
press LOCKOUT so L/O disappears from the display. You can also manually
select locked-out channels.
Note: There must be at least one active channel in each bank. You
cannot lock out all channels.
TURNING CHANNEL-STORAGE BANKS ON AND OFF
You can turn each channel-storage bank on and off. When you turn off a
bank, the scanner does not scan any of the 10 channels in that bank.
While scanning, press the number key corresponding to the bank you want
to turn on or off. If the memory bank indicator is on, the bank is
turned on and the scanner scans all channels within that bank that are
not locked out. If the indicator is off, the scanner does not scan any
of the channels within that bank. (You can manually select any channel
in a bank, even if the bank is turned off.)
Note: You cannot turn off all banks. One bank is always active.
PRIORITY
You can scan through channels and still not miss an important or
interesting call on a specific channel. When a channel is selected as
the priority channel and the priority feature is turned on, the scanner
checks that channel every two seconds, and stays on the channel if there
is activity. PRI appears on the display whenever the scanner is set to
the priority mode.
To program a channel as the priority channel, press PROGRAM, the desired
channel number and then PRIORITY. P appears beside the channel number.
You can only select one channel as the priority channel.
To turn on the priority feature, press PRIORITY while the scanner is in
either manual mode or scan mode. To turn off the priority feature, press
PRIORITY until PRI disappears from the display.
NOTES: Selecting a monitor memory while the priority feature is turned on
will cancel the priority feature.
Channel 1 is initially set as the priority channel.
USING THE DISPLAY BACKLIGHT
You can turn on the display's backlight for easy viewing in the dark.
Press KEYLOCK/ to turn on the display light for 15 seconds. To turn off
the light before 15 seconds elapses, press KEYLOCK/ again.
Note: Do not hold KEYLOCK down or it will lock up the keypad.
LISTENING TO THE WEATHERBAND
The FCC (Federal Communications Commission) has allocated eleven channels
for use by the National Oceanic and Atmospheric Administration (NOAA).
We have preprogrammed the scanner with the seven frequencies most
commonly used by NOAA. To hear your local forecast and regional weather
information, simply press WX/E. The scanner begins scanning through the
weather band, and WX appears on the display.
The scanner should stop within a few seconds, and then you hear the local
weather broadcast. If the broadcast is weak, you can press WX/E again
to scan through the rest of the weather band.
