PRO-72 50-Channel Portable Scanner
(200-0566) Operation Faxback Doc. # 39449
Turning ON The Scanner and Setting Squelch
1. Turn SQUELCH fully counterclockwise before you turn on the scanner.
2. Turn VOLUME clockwise until you hear a hissing sound. Turn SQUELCH
clockwise, just until the hissing sound stops.
NOTE: To listen to a weak or distant station, turn SQUELCH counter-
clockwise. If reception is poor, turn SQUELCH clockwise to cut
out weak transmissions.
Searching For and Storing Active Frequencies
Your scanner can store up to 51 frequencies. Each frequency can be stored
in either a memory called a channel, or the temporary memory called a moni-
tor. This scanner has 50 channels and one monitor memory.
You can store frequencies using any of these methods.
Manually enter and store a specific frequency (see "Storing Frequencies"
below).
Search for active frequencies within a range of preprogrammed frequencies
and store selected frequencies in the scanner's channel memories (see
"Using Band Search" below).
Search for active frequencies starting directly from one specific freq-
uency and store a frequency in the scanner's monitor memory (see "Using
Direct Search" below).
Recall the monitor memory frequency and move that frequency to a channel
memory (see "Using the Monitor Memory" below).
Active Frequency References
Good references for active frequencies are Radio Shack's "Beyond Police
Call", "Police Call Radio Guide Including Fire and Emergency Services",
"Aeronautical Frequency Directory" and "Radio!" magazine. We update these
references often, so be sure to get a current copy.
If you do not have a reference to frequencies in your area, or if you want
to search for unlisted frequencies, use a band search or direct search. See
also "Guide to the Action Bands" on Faxback Doc. # 39451 in this manual.
Storing Frequencies
Follow these steps to store frequencies into your scanner's channels.
1. Press PGM. PGM appears on the display to indicate the scanner is in
the programming mode.
2. Use the number keys to enter the channel number (1-50) where you want
to store the frequency, then press PGM again. Or, repeatedly press PGM
until the desired channel number appears.
NOTES: If you enter an invalid channel number, Error appears on the
display. Simply repeat this step.
If a frequency is currently stored in the selected channel, the
channel number does not flash but the current frequency number
appears on the display. You can either repeat this step to
select a different channel, or replace the current frequency
with a new one.
3. Use the number keys and ./DLY to enter the frequency (including the
decimal point) you want to store in that channel.
4. Press E/L-OUT to store the frequency. The selected channel number
stops flashing, indicating that the selected channel is stored.
NOTES: If you entered an invalid frequency in Steps 3, Error appears
on the display after you press E/L-OUT. Simply repeat Steps
3 and 4 and enter a valid frequency in Step 3.
Your scanner automatically rounds the entered frequency down to
the nearest valid frequency. For example, if you try to enter a
frequency of 151.4730, your scanner accepts it as 151.4700.
If you entered a frequency that is already stored in another
channel, dUPL (duplicate) and the lowest-numbered channel con-
taining the duplicate frequency flash on the display for about
3 seconds.
To store the duplicate frequency, press E/L-OUT again. To
store a different frequency, repeat Steps 3 and 4, and enter
a different frequency in Steps 3.
5. Repeat Steps 2-4 to program another channel.
Using Band Search
If you do not know of a frequency to store, you can search your scanner's
preprogrammed search bands for active frequencies, then store any that you
find into your scanner's channels.
Follow these steps to search for and store active frequencies using band
search.
1. Press BAND. The last selected band number (b followed by a number, such
as b2) and the associated frequency search range appear on the display.
2. To search a different band, within 2 seconds, enter the desired band
number (0-9, see Faxback Doc. # 39445 for descriptions) or repeatedly
press BAND until the desired band number appears on the display. After
about 2 seconds, SRCH /\ appears, the next available channel flashes,
and the scanner begins searching rapidly upward in that band (from
lowest to highest frequency) for an active frequency.
NOTES: To select a different band after the scanner begins searching
the current band, simply repeat this step.
To reverse the rapid search direction at any time, press and
hold \/ or /\ for about 1 second.
To search the selected band upward or downward in small incre-
ments (in steps of 5 or 12.5 kHz, depending on the band), press
and release /\ or \/ so /\ or \/ disappears from the display.
See "Specified intervals" on Faxback Doc. # 39451.
3. When the scanner finds an active frequency, it stops scanning and
displays that frequency's number. To store that frequency in the chan-
nel currently flashing on the display, simply press E/L-OUT. The scan-
ner stores the frequency, then the next available channel flashes on the
display.
NOTES: You cannot store an active frequency in the monitor memory
during band search.
After you store a frequency into the last available channel,
--ch appears instead of a channel number. If you try to store
a channel while --ch appears, CH FULL appears briefly on the
display. In order to store more frequencies, you must clear
some channels. See "Clearing a Stored Channel" below.
4. To search for another active frequency in the selected band, press and
hold /\ or \/ for about 1 second, then repeat Steps 3.
To select a different band then search for another active frequency,
repeat Steps 2 and 3.
Using Direct Search
During a direct search, the scanner searches upward or downward, starting
from a frequency you specify. Follow these steps to use direct search.
1. Press MANUAL or PGM, then enter the frequency 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 MANUAL or PGM, enter the desired channel number,
then press MANUAL or PGM again.
2. Press and hold /\ or \/ for about 1 second to search upward or downward.
-d, SRCH, and /\ or \/ appear on the display.
3. When the scanner stops on an active frequency, you can either:
Press O/MON to store it in the monitor memory.
Press and hold /\ or \/ to continue the search.
Using The Monitor Memory
After you store a frequency in the scanner's monitor memory during a direct
search, you can recall it and move it to one of your scanner's channel mem-
ories.
Listening to the Monitor Memory
To recall a frequency stored in the monitor memory, simply press MANUAL
then O/MON. MAN then MON and the stored frequency appear on the display.
Moving a Frequency from the Monitor Memory to a Channel
1. Press MANUAL, 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. MON and the monitor memory frequency appear on the display.
3. Press E/L-OUT. MON disappears, the channel number stops flashing and
the frequency is stored in the selected channel.
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 upward 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 a 2-Second Delay" on Faxback
Doc. # 39450.
To set the scanner to remain on the current channel, even after the
transmission stops, press MANUAL 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" on Faxback Doc.
# 39450.
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 MANUAL.
2. Enter the channel number.
3. Press MANUAL 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. Select the channel that you want to clear.
2. Press PGM. PGM appears on the display.
3. Press CLEAR. The frequency number flashes on the display.
4. Press E/L-OUT, L/O (lockout - see "Locking Out Channels" on Faxback Doc.
# 39450) appears, the channel number flashes, and 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 (1-50), then press PGM again. Or, repeatedly press PGM until
the desired channel number appears. Then repeat Steps 3-4.
