PRO-74 100-Channel VHF/UHF/Air/800 MHz Race Scanner
(200-0513) Operation Faxback Doc. # 47323
TURNING ON THE SCANNER AND SETTING SQUELCH
Note: Make sure an antenna is connected to the scanner before you turn it
on.
1. Turn SQUELCH fully counterclockwise.
2. Turn VOLUME clockwise until it clicks and you hear a hissing sound.
3. Turn SQUELCH clockwise, then leave it set to a point just after the
hissing sound stops.
Notes: If you have not stored frequencies into any channels, the scanner
does not scan.
If the scanner picks up unwanted, partial, or very weak
transmissions, turn SQUELCH clockwise to decrease the scanner's
sensitivity to these signals. If you want to listen to a weak or
distant station, turn SQUELCH counterclockwise.
If SQUELCH is adjusted so you always hear a hissing sound, the
scanner does not scan properly.
STORING KNOWN FREQUENCIES INTO CHANNELS
Good references for active frequencies are the RadioShack "Beyond 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 a frequency into a channel.
1. Press MAN, enter the channel number where you want to store a
frequency, then press PROG. The channel number appears.
2. Use the number keys and CLEAR/(*) to enter the frequency (including
the decimal point) you want to store.
3. Press E to store the frequency into the channel.
Notes: If you entered an inappropriate frequency in Step 2, Error
appears and the scanner beeps three times. Simply repeat
Steps 2 and 3.
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 151.475.
Your scanner automatically delays scanning for 2 seconds after
a transmission ends before it proceeds to the next channel.
4. To program the next channel in sequence, press PROG and repeat Steps 2
and 3.
Note: If you previously stored a car number in a channel (see "Storing
a Car Number and Frequency" below), the scanner clears the
number when you store a new frequency into a channel.
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. # 47322). You can search for auto racing, marine,
VHF, aircraft, military, amateur radio, government, UHF, TV, and 800 MHz
transmissions even if you do not know the specific frequencies that are
used in your area.
1. Press BAND. A service bank's name, SEARCH, and the frequency search
range appear.
Note: The frequency search range does not appear if the CAR or MRN CH
service bank is selected.
2. To select a different service bank, repeatedly press (/\) or (\/)
until the desired bank name appears.
3. Press BAND. The scanner starts searching the frequencies within that
service bank.
Note: To change the search direction, press (/\) or (\/).
4. When the scanner stops on a transmission, quickly press either:
(\/) or (/\) to continue searching.
HOLD to stop searching so you can listen to the transmission. HOLD
appears.
To release hold and continue searching, press HOLD or hold down (\/)
or (/\) for more than 1 second.
Notes: To step through the frequencies while HOLD is displayed, press
(\/) or (/\).
If you tune to a search skip frequency, L/O appears (see
"Search Skip Memory" below).
To store a frequency into a channel while the frequency is
paused or held, see "Storing Active Frequencies" below.
Searching from a Selected Frequency
If you do not have a reference to frequencies in your area, you can search
for transmissions starting with a frequency you select.
1. Press MAN.
2. To start the search from a frequency, enter it using the number keys
and CLEAR/(*). Or, to start the search from a frequency stored in a
channel, enter the channel number, then press MAN.
3. Press (\/) to search downward or (/\) to search upward from the
selected frequency. -d-, SEARCH, and (\/) or (/\) appear.
4. When the scanner stops on a transmission, quickly press either:
(/\) or (\/) to continue searching
HOLD to stop searching so you can listen to the transmission. HOLD
appears.
To release hold and continue searching, press HOLD or hold down (\/)
or (/\) for more than 1 second.
Notes: To step through the frequencies while HOLD is displayed,
press (\/) or (/\).
If you tune to a search skip frequency, L/O appears (see
"Search Skip Memory" below).
To store a frequency into a channel while the frequency is
paused or held, see "Storing Active Frequencies," below.
Storing Active Frequencies
To store an active frequency into a channel, press PROG while the
frequency is paused or held. The lowest available channel number flashes.
To enter the frequency into that channel, press E.
To change the channel, enter the desired channel number then press PROG.
The frequency currently stored in that channel (if any) appears for about
2 seconds, then the news frequency appears. Press E to store the new
frequency.
Notes: If you previously stored a car number and frequency in a channel
(see "Storing a Car Number and Frequency" below), the scanner
clears the number and frequency when you store a new frequency
into that channel.
If there are no empty channels, the channel number changes to 1
and FULL appears. To clear FULL from the display, press CLEAR.
SEARCH SKIP MEMORY
You can skip up to 20 specified frequencies during a service bank, direct,
or weather search. This lets you avoid unwanted frequencies or ones you
have already stored in a channel.
To skip a frequency, press S/S when the scanner stops on the frequency
during a search. The scanner stores the frequency in memory and
automatically resumes the search.
To clear a single frequency from search skip memory so the scanner can
stop on it during a search, follow these steps.
1. Press HOLD to hold the search.
2. Press (/\) or (\/) to select the frequency. L/O appears.
3. Press S/S. L/O disappears from the display.
To clear all the search skip frequencies at once, during a search, press
HOLD, then hold down S/S until the scanner beeps twice (about 3 seconds).
Notes: If you skip all the frequencies in the weather band, the scanner
will not start searching. In this case, the scanner sounds three
beeps.
If you program more than 20 frequencies to skip, each new frequency
replaces one you already stored, starting from the first frequency
you stored.
You can manually select a skipped frequency. L/O appears on the
display when you select a skipped frequency.
MANUALLY SELECTING A CHANNEL
You can continuously monitor a single 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 want to monitor a specific channel.
Note: You cannot use this procedure to select a car number. See "Viewing
Frequencies Associated with a Car Number" below to select a car
number.
To manually select a channel, press MAN, enter the channel number, then
press MAN again. Or, if your scanner is scanning and stops at the desired
channel, press MAN once.
Pressing MAN additional times causes your scanner to step through the
channels. To resume scanning, press SCAN.
SCANNING CHANNELS
To begin scanning channels, press SCAN. The scanner scans through all
non-locked channels in all banks that are turned on, from the lowest to
the highest channel number. (See "Turning Memory Banks On and Off" and
"Locking Out Channels" in Faxback Doc. # 47324).
When the scanner finds a transmission, it stops on it. Two seconds after
the transmission ends, the scanner resumes scanning.
Note: If SQUELCH is adjusted so you always hear a hissing sound, the
scanner does not scan properly.
DELETING A FREQUENCY FROM A CHANNEL
1. Press PROG.
2. Enter the channel number that contains the frequency you want to
delete, then press PROG.
3. Press DEL. The frequency is deleted.
LISTENING TO WEATHER BROADCASTS
The FCC (Federal Communications Commission) has allocated frequencies for
use by the National Oceanic and Atmospheric Administration (NOAA).
Regulatory agencies in other countries have also allocated frequencies for
use by their weather reporting authorities.
Your local weather reporting authority broadcasts your local forecast and
regional weather information on one or more of these frequencies. If your
scanner is within a weather reporting authority's broadcast range, you can
scan these frequencies.
Your scanner has 7 weather service frequencies preprogrammed. See
"National Weather Frequencies" in Faxback Doc. # 17653 for a list of these
frequencies.
To hear your local forecast and regional weather information, simply press
WX. Your scanner scans through the weather frequencies. Your scanner
should stop within a few seconds on your local weather broadcast.
To manually tune to a specific preprogrammed weather frequency, press WX,
then HOLD. Repeatedly press (/\) or (\/) to move forward or backward
through the frequencies.
USING THE PRO-74 AT THE RACES
The PRO-74 is specially designed to help you listen to communications at
auto races. Drivers and their pit crews and corner watchers, pace car
drivers, security officers, emergency personnel, track officials, and
representatives of governing organizations such as NASCAR, SCCA, and NHRA
all use radios to communicate with each other during a race. You might
also hear transmissions from the news media and reporters, local police
departments, and paramedics and doctors at the local hospital. You can
even listen to broadcasts by parking lot employees at the track, so you
can find the best possible parking place when you arrive.
The scanner's quick-track memory lets you store a car number and frequency
in each of the scanner's channels, associate one or more frequencies
stored in channels with a car number and recall any frequencies associated
with that car number by entering the number. You can store one car number
by itself, one car number and frequency or one frequency by itself in each
channel (for up to 100 car numbers and frequencies).
For example, if you want to listen to communications between the driver of
car number 24 and that driver's pit crew, find all the frequencies used by
the driver's team by using the steps in "Searching the Service Banks"
above, using the supplied frequency guide, "Searching from a Selected
Frequency" above, or using frequencies you already know, then store a car
number and the frequencies associated with that car number in the
scanner's channels. Then, you can display the car number as you scan those
frequencies by using the information in "Scanning by Car Number" below.
STORING A CAR NUMBER AND FREQUENCY
You can store a car number and frequency in each of the scanner's
channels, and you can recall any frequencies associated with the car
number by entering the number. You can store one car number in each
channel (for up to 100 car numbers).
Note: After you store a car number and a frequency, you can store
additional frequencies then associate those frequencies with the
same car number. See "Adding Frequencies to a Car Number" below.
Follow these steps to store a car number and frequency.
1. Press MAN then RACE. RACE and Car No? - - - appears.
2. Enter the car number. If the number is one or two digits, enter the
number, then press RACE. If the number is three digits, enter the
number only. The car number and - - -.- - - appear.
Notes: If you add one or more leading zeros to a single-digit car
number, your scanner recognizes them as different car numbers.
For example, you can enter 5 for one car number, 05 for
another car number, and 005 for another car number.
To clear the display, press CLEAR/* before you press RACE.
3. Enter the frequency (including the decimal point) you want to
associate with the car number by using the number keys and CLEAR/(*).
4. Press E to store the frequency. The car number and frequency are
stored in the first available channel.
Adding Frequencies to a Car Number
Follow these steps to select a car number then associate additional
frequencies with that car number.
1. Press MAN then RACE. RACE and CAR No? - - - appears.
2. Enter the car number. If the number is one or two digits, enter the
number, then press RACE. If the number is three digits, just enter
the number. The car number and the first frequency associated with
that number appears.
3. Repeatedly press (/\) or (\/) until - - -.- - - appears.
4. Enter the frequency (including the decimal point) you want to
associate with the displayed car number by using the number keys and
CLEAR/(*).
5. Press E to store the frequency. The frequency is associated with the
car number you entered.
Viewing Frequencies Associated with a Car Number
After you store a car number and associate frequencies with that number,
you can view all frequencies associated with the number.
1. Press MAN then RACE. RACE and Car No? - - - appears.
2. Enter the car number. If the number is one or two digits, enter the
number, then press RACE. If the number is three digits, just enter
the number. One of the frequencies associated with the car number
appears.
3. Repeatedly press (/\) or (\/) to view each of the frequencies
associated with the car number you entered. When you have viewed all
the frequencies, the display shows - - -.- - -.
Deleting a Frequency from a Car Number
1. Recall the car number.
2. Repeatedly press (/\) or (\/) until the frequency you want to delete
appears.
3. Hold down DEL for about 1 second. The scanner beeps and the frequency
disappears.
SCANNING BY CAR NUMBER
Once you store car numbers into channels, you can set the scanner so it
displays the car numbers you assigned to the channels as it scans them.
To scan by car number, repeatedly press RACE until BANK and RACE appear,
then press SCAN. As the scanner scans channels, the car numbers you stored
appear in the order you stored them into their channels, from the lowest
to the highest channel.
Notes: If no car number is assigned to a channel, - - - appears instead
of the car number.
If SQUELCH is adjusted so you always hear a hissing sound, the
scanner does not scan properly.
FINDING WHAT CAR NUMBERS ARE IN WHAT CHANNELS
If you are listening to a channel and want to know what car number you are
hearing, simply press RACE twice. If a car number has been associated with
this frequency, the car number and frequency appear. Press RACE twice to
return to normal channel listening.
To see what car numbers are stored, press MAN then RACE, then repeatedly
press DATA. The car numbers (from lowest channel number to highest) show.
