PRO-75 200-Channel Portable Scanner
(200-0312B) Operation Faxback Doc. # 59443
Turning on the Scanner and Setting Squelch
1. Turn SQUELCH fully counterclockwise until the indicator points to MIN
before you turn on the scanner.
2. To turn on the scanner, turn VOLUME clockwise until you hear a hissing
sound.
3. Turn SQUELCH clockwise, just until the hissing sound stops.
Notes: If you have not stored frequencies into any channels, the
scanner does not scan.
To listen to a weak or distant station, turn SQUELCH counter
clockwise. If reception is poor, turn SQUELCH clockwise to cut
out weak transmissions.
If SQUELCH is adjusted so you always hear a hissing sound, the
scanner does not scan properly.
4. To turn off the scanner when you finish, turn VOLUME counterclockwise
to OFF.
Storing Known Frequencies into Channels
Good references for active frequencies are the RadioShack Police Call,
Aeronautical Frequency Directory, and Maritime Frequency Directory. We
update these directories every year, so be sure to get a current copy.
Follow these steps to store frequencies into channels.
1. Press PGM, enter the channel number (1-200) where you want to store a
frequency, then press PGM again. The channel number appears.
2. Use the number keys and ( . ) to enter the frequency (including the
decimal point) you want to store.
3. Press ENTER to store the frequency into the channel. Then MHz appears.
Notes: If MHz does not appear, start again at Step 1.
If you made a mistake in Step 2, Error appears and the scanner
beeps when you press ENTER. Simply start again from Step 2.
Your scanner automatically rounds the entered frequency to the
nearest valid frequency. For example, if you enter a frequency
of 151.473, your scanner accepts it as 151.470.
If you entered a frequency that is already stored in another
channel, the scanner beeps three times and displays the lowest
channel number where the frequency is already stored, and
-dUPL-, then the frequency flashes. If you want to store the
frequency anyway, press ENTER again. Press MON/CL to clear the
frequency.
Press DELAY if you want the scanner to pause 2 seconds on this
channel after a transmission ends before it proceeds to the
next channel (see "Using the Delay Function" in Faxback Doc. #
59444). The scanner also stores this setting in the channel.
4. To program the next channel in sequence, press PGM and repeat Steps 2
and 3.
Finding and storing Active Frequencies
Searching the Service Banks
Your scanner contains groups of preset frequencies called service banks.
Each service bank is associated with a specific activity (see "Service
Banks" in Faxback Doc. # 59442). You can search for fire/police, air,
ham, and marine transmissions even if you do not know the specific
frequencies that are used in your area. Then you can store the frequencies
you found into the scanner's channels or monitor memories.
Note: You can use the scanner's delay feature while searching the service
banks, see "Using the Delay Function" in Faxback Doc. # 59444.
1. Press BAND. The last selected band name (such as HAM), SRCH, -b-, /\,
frequency and the group number (if any) appear on the display.
2. To select a different band, repeatedly press BAND until the desired
band name appears on the display. After about 2 seconds, the scanner
begins searching rapidly in that band for an active frequency.
Notes: To reverse the search direction at any time, hold down /\ or \/
for about 1 second.
To search the band up or down in small increments (see "Service
Banks" in Faxback Doc. # 59442 for frequency steps), repeatedly
press and release /\ or \/.
To pause the search while receiving a signal press and release
/\ or \/. To continue the search, hold down /\ or \/.
To search through the frequencies, hold down /\ or \/ for about
one second. The scanner tunes through the frequencies until an
active frequency is found. The scanner automatically begins
searching again when the transmission ends on that frequency.
3. When the scanner finds an active frequency, it stops searching and
displays the frequency's number. To store the displayed frequency in
the lowest available channel, press ENTER. The channel and frequency
flash twice, and the scanner stores the displayed frequency. The
scanner then continues to search for frequencies.
Notes: If there is no empty channel, Ch-FULL appears. To store more
frequencies, you must clear some channels. See "Clearing a
Stored Channel" below. To continue searching after Ch-FULL
appears, press and hold down /\ or \/.
If you entered a frequency that is already stored in another
channel, -dUPL- (duplicate) and the lowest-numbered channel
containing the duplicate frequency flash on the display for
about 3 seconds. If you want to store the frequency anyway,
press ENTER again. You can then delete the frequency later.
See "Clearing a Stored Channel" below.
4. To store the displayed frequency in the monitor memory, press MON/CL.
The monitor memory number, M, and the frequency flash twice.
5. To search for another active frequency in the selected band, hold down
/\ or \/ for about 1 second. To select a different band and search for
another active frequency, repeat Steps 2-3.
Using Direct Search
During a direct search, the scanner searches up or down, starting from a
frequency you specify. Follow these steps to use direct search.
Note: You can use the scanner's delay feature while using direct search.
1. Press MAN or PGM, then enter the frequency (including the decimal
point) you want to use as a starting point for the search.
Note: To start from a frequency already stored in one of your
scanner's channels, press MAN or PGM, enter the desired channel
number, then press MAN or PGM again.
2. Hold down /\ or \/ for about 1 second to search up or down. -d-, SRCH,
and /\ or \/ appear on the display.
Notes: To reverse the rapid search direction at any time, hold down /\
or \/ for about 1 second.
To search up or down the selected band in small increments (in
steps 5, 12.5, or 25 kHz), press and release /\ or \/.
To pause the search, press and release /\ or \/. To continue
the search, hold down /\ or \/.
To search through the frequencies, hold down /\ or \/ for about
one second. The scanner tunes through the frequencies until an
active frequency is found. The scanner automatically begins
searching again when the transmission ends on that frequency.
3. When the scanner finds an active frequency, it stops searching and
displays the frequency's number. To store the displayed frequency in
the lowest available channel, press ENTER. The channel and frequency
flash twice, and the scanner stores the displayed frequency. The
scanner continues to search for frequencies.
Notes: If there is no empty channel, Ch-FULL, appears. To store more
frequencies, you must clear some channels. See "Clearing a
Stored Channel" below. To continue searching after Ch-FULL
appears, press and hold down /\ or \/.
If you entered a frequency that is already stored in another
channel, -dUPL - (duplicate) and the lowest-numbered channel
containing the duplicate frequency flash on the display for
about 3 seconds. If you want to store the frequency anyway,
press ENTER again.
4. To store the displayed frequency in the monitor memory, press MON/CL.
M, the monitor memory number, and the frequency flash twice.
5. To search for another active frequency, hold down /\ or \/ for about 1
second.
Using the Monitor Memory
Monitor Memories
The scanner also has 20 monitor memories that you can use to temporarily
store frequencies while you decide whether to save them into channels.
This is handy for quickly storing an active frequency when you are
searching through an entire band.
You can store a frequency into a monitor memory during a bank or direct
search. See "Finding and Storing Active Frequencies" above.
You can select monitor memories manually, but you cannot scan them. See
"Listening to the Monitor Memory" below.
After you store a frequency in the scanner's monitor memory during a
search, you can recall it and move it to one of your scanner's channel
memories. You can store up to 20 frequencies in the monitor memory.
Listening to the Monitor Memory
To recall a frequency stored in the monitor memory, press MAN then MON/CL.
M, monitor memory number, and CH flash and the current monitor memory
frequency appears on the display. To select other monitor memories, enter
the desired monitor memory's number (1-20), then press MON/CL again. The
selected monitor memory's frequency appears.
Moving a Frequency from the Monitor Memory to a Channel
1. Press PGM, enter the channel number where you want to store the
frequency, then press PGM. PGM and the selected channel number appear
on the display.
2. Press MON/CL. M, a monitor memory number and CH flash, and the monitor
memory frequency appear on the display.
3. Enter the desired monitor memory's number (1-20), then press MON/CL
again. The selected monitor memory's frequency appears.
4. Press ENTER. The scanner stores the frequency in the selected channel.
5. To move another monitor memory frequency to the next channel, press
PGM and repeat Steps 2-4.
Scanning the Stored Channels
To set the scanner to continuously scan through all channels with stored
frequencies, simply press SCAN. SCAN and /\ appear on the display, and
the scanner begins to rapidly scan up until it finds an active frequency.
If the scanner finds an active frequency, it stops and displays that
channel and frequency number, then it automatically begins scanning again
when the transmission ends on that frequency.
Notes: To reverse the scanning direction, press /\ or \/.
To set the scanner to remain on the current channel for 2 seconds
after the transmission ends, see "Using the Delay Function" in
Faxback Doc. # 59444.
To set the scanner to remain on the current channel, even after
the transmission stops, press MAN at any time during the
transmission so MAN appears and SCAN disappears from the display
(see "Monitoring a Stored Channel" below).
To lock out channels so the scanner does not stop for a
transmission on those channels, see "Locking out Channels and
Frequencies" in Faxback Doc. # 59444.
Turning Channel-Storage Banks Off and On
To turn off a channel-storage bank (1-10), press SCAN to see which banks
are currently on. Storage banks are on when they have a bar underneath
them and off when no bar appears underneath them. Press the bank's number
key so the bar under the bank's number disappears.
Note: The scanner does not scan any of the channels within the banks you
have turned off.
To turn on a channel-storage bank (1-10) press SCAN, and then press the
bank's number key so a bar appears under the bank's number.
Notes: You cannot turn off all banks. There must be at least one active
bank.
You can manually select any channel in a bank, even if the bank is
turned off.
When you turn on the bank while scanning, the scanner moves to the
selected bank's channel and continues scanning.
Monitoring a Stored Channel
You can continuously monitor a specific channel without scanning. This is
useful if you hear an emergency broadcast on a channel and do not want to
miss any details - even though there might be periods of silence - or if
you simply want to monitor that channel.
Follow these steps to manually select a channel.
1. Press MAN.
2. Enter the channel number (1-200).
3. Press MAN again.
Clearing a Stored Channel
If you no longer want a frequency stored in a channel (and you do not want
to replace that frequency with a different one), follow these steps to
clear the stored frequency.
1. Press MAN to get out of the service banks or to stop scanning.
2. To select the desired channel number, use the number keys to enter
that channel number (1-200), then press MAN.
3. Press PGM. PGM appears.
4. Press 0, then press ENTER. The frequency number changes to 000.0000
on the display to indicate the channel is cleared.
5. To clear another channel, use the number keys to enter that channel
number (1-200), then press PGM again. Or repeatedly press PGM until
the desired channel number appears. Then repeat Step 4.
