PRO-2040 100-Channel Programmable Home Scanner
(220-0414) Operation Faxback Doc. # 17766
TURNING ON THE SCANNER/SETTING THE VOLUME AND SQUELCH
1. Turn SQUELCH fully clockwise.
2. Press POWER to turn on the scanner. The scanner continuously scans the
unlocked channels.
NOTE: The first time the scanner is turned on, the channels might not
have any frequencies stored in them, but the scanner will
continuously scan the empty channels anyway.
3. Press MANUAL to stop the scanning. The display shows the current
channel.
4. Turn VOLUME/MIN/MAX clockwise to set the scanner's volume about 1/4 of
the way between MIN and MAX.
5. Turn the SQUELCH counterclockwise until a hissing noise is heard.
6. Adjust VOLUME/MIN/MAX to a comfortable level.
7. Slowly turn SQUELCH clockwise until the hissing noise stops.
SQUELCH TIPS: If the scanner picks up unwanted or weak transmissions,
slightly turn SQUELCH clockwise to decrease receiver
sensitivity.
If the scanner does not pick up any transmissions, slightly
turn SQUELCH counterclockwise to increase receiver
sensitivity.
FINDING BIRDIE FREQUENCIES
Birdies are operating frequencies generated and used inside the scanner's
receiver. These operating frequencies could interfere with broadcasts on
the same frequencies and make them difficult or impossible to receive.
These are the most common birdies to watch for:
31.0500 MHz 134.550 MHz
127.2500 MHz 136.050 MHz
128.1875 MHz 138.050 MHz
128.2500 MHz 140.275 MHz
129.6875 MHz 144.900 MHz
132.0500 MHz 171.250 MHz
132.2625 MHz
If one of these frequencies is stored into a channel, the user might only
hears noise when the scanner stops on that frequency. If the interference
is not severe, turning SQUELCH clockwise might cut out the birdie.
To find the specific birdies for a scanner:
1. Disconnect the antenna and move it away from the scanner.
NOTE: Make sure that no other nearby radios or TVs are turned on.
2. Search every frequency band from its lowest frequency to the highest
(see "Searching For and Temporarily Storing Active Frequencies").
If searching stops (as if the scanner has found a signal) but there is no
sound, that frequency might be a birdie.
For future reference, a user should record all the birdies in their
particular scanner.
MANUALLY STORING FREQUENCIES IN CHANNELS
Up to 100 frequencies can be manually stored into a scanner's channels.
Radio Shack sells some good references for active frequencies, such as
"Police Call Radio Guide Including Fire and Emergency Services", "Official
Maritime Frequency Directory", and "Official Aeronautical Frequency
Directory".
Radio Shack updates these directories every year, so be sure to get a
current copy. If a user does not have a reference to frequencies in their
area, use a limit or direct search to find a transmission.
Follow these steps to manually store frequencies:
1. Press MANUAL to stop the scanning.
2. Enter the desired channel number to store the frequency at.
3. Press PGM. 000.0000MHz, PROGRAM, BAND, the bank number, and the
selected channel number appear on the display.
4. Enter the frequency the user wants to store, including the decimal
point.
NOTES: Frequencies are separated from each other in the following steps:
Frequencies Steps
29.0 - 108.0 MHz 5 kHz
108 - 136.975 MHz 12.5 kHz
137.0 - 300.0 MHz 5 kHz
300 - 3000 MHz 12.5 kHz
When entering a frequency, the scanner automatically rounds it to
the nearest valid number. For example, if the 151.473 frequency is
entered, the scanner rounds it up to 151.475.
5. Press ENTER to store the frequency into the selected channel.
NOTE: If a mistake is made in Step 4, Error appears on the display.
Repeat Steps 4 and 5.
6. To program the next channel in sequence, repeat Steps 3 - 5.
To program other channels not in sequence, repeat Steps 2 - 5.
SEARCHING FOR AND TEMPORARILY STORING ACTIVE FREQUENCIES
Frequencies can be searched using a limit or direct search, then the user
either skips selected frequencies or temporarily stores frequencies into
monitor memories.
Limit Search
A limit search provides for searching active transmissions within a
specified range of frequencies.
NOTE: The scanner's delay feature can be used while using limit search
(see "Delay").
Follow these steps to search for active frequencies:
1. Press PGM, them LIMIT. Lo and a frequency appear on the display.
2. Using the number keys, enter the lowest frequency (including the
decimal point) the user wants to search within the desired frequency
range, then press ENTER.
NOTE: If an invalid frequency is entered, Error appears on the
display. To correct this, simply repeat the step.
3. Press LIMIT. Hi and a frequency appear on the display.
4. Using the number keys, enter the highest frequency the user wants
to search within the desired frequency range, then press ENTER.
5. Press UP TRIANGLE to search upward from the lower to the upper limit,
or press DOWN TRIANGLE to search downward form the upper to the lower
limit. -L-, SEARCH, and UP TRIANGLE or DOWN TRIANGLE appear, and the
next available monitor memory flashes on the display.
6. When the scanner finds an active frequency the user wants to monitor,
the following options are available:
To store the displayed frequency into the current monitor
memory, quickly press MON.
To continue the search, press UP/DOWN TRIANGLE.
To hold the frequency, press LIMIT. -H- appears on the display.
Press LIMIT again to exit the hold mode and resume the limit search.
NOTES: If the UP or DOWN TRIANGLE is pressed during the hold mode, the
frequency changes in the current step increment toward the upper or
lower limits.
If a search skip frequency is tuned, the display shows LOCKOUT (see
"Search Skip Memory).
Direct Search
A direct search allows the user to specify a starting frequency, then
search for active transmissions above or below the specified frequency.
NOTE: The scanner's delay feature can be used while using direct search
(see "Delay").
1. Press MANUAL.
2. Using the number keys, enter the frequency (including the decimal
point) the user wants to start the search from, or the channel number
containing the starting frequency, then press MAN or PGM to select the
channel.
3. Press UP TRIANGLE to search up or DOWN TRIANGLE to search down starting
from the specified frequency or channel. -d-, SEARCH, and the UP/DOWN
TRIANGLE appear, and the next available monitor memory flashes on the
display.
NOTE: If an invalid frequency is entered, Error appears on the
display. To correct this, repeat Steps 2 and 3.
4. When the scanner finds an active frequency the user wants to monitor,
do one of the following:
To store the frequency into the current monitor memory, press MON.
To continue the search, press UP/DOWN TRIANGLE.
To hold the frequency, press LIMIT. -h- appears on the display.
Press LIMIT again to exit the hold mode and resume the direct search.
NOTES: If the UP/DOWN TRIANGLES are pressed during the hold mode, the
frequency changes in the current step increment toward the
upper or lower limits.
If a search skip frequency is tuned, the display shows
LOCKOUT (see "Search Skip Memory").
Search Skip Memory
Specified frequencies can be skipped during a limit or direct search.
This lets the user avoid unwanted frequencies or ones already stored in a
channel. Up to 50 skip frequencies can be programmed into the scanner's
memory.
To skip a frequency, press L/O/SEARCH SKIP when the scanner stops on the
frequency during a limit or direct search.
To clear a single frequency from skip memory so the scanner can stop on it
during a limit or direct search, press MANUAL to hold the search, enter the
frequency, then press L/O/SEARCH SKIP until LOCKOUT disappears from the
display.
To clear all the skip frequencies at once, while in the search mode, press
and hold L/O/SEARCH SKIP until the scanner beeps twice.
NOTES: If more than 50 skip frequencies are programmed, each new frequency
replaces earlier ones, starting from the first stored frequency.
The user can select the skipped frequency when the scanner is in
the hold mode. The scanner displays LOCKOUT when a skipped
frequency is selected.
LISTENING TO MONITOR MEMORIES
After temporarily storing frequencies into the scanner's monitor memories,
listen to them by pressing MANUAL, MON, then the number for the desired
monitor memory.
NOTE: To listen to the monitor memories, the priority channel feature must
be turned off (see "Designating a Priority Channel").
MOVING A FREQUENCY FROM A MONITOR MEMORY TO A CHANNEL
1. Press MANUAL to stop the scanning.
2. Enter the channel number where the monitor frequency will be stored,
then press PGM. PROGRAM appears on the display.
3. Press MON, then enter the monitor memory number that has the frequency
to store into the channel. MON and the entered frequency appear, and
the channel number blinks on the display.
4. Press ENTER. The scanner stores the frequency into the selected
channel.
SCANNING THE STORED CHANNELS
To scan the stored channels, press SCAN. The scanner scans through all the
stored channels except the ones the user locks out (see "Locking Out
Channels").
If needed, readjust SQUELCH to eliminate the hissing sound between
transmissions.
Turning Channel-Storage Banks On and Off
The scanner can be set to scan more efficiently by turning selected channel
storage banks on and off. When turning off a bank, the scanner does not
scan any of the 10 channels in the bank.
While scanning, press the number key corresponding to the bank the user
wants 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.
NOTES: Any channel in the bank can be manually selected, even if the bank
is turned off.
The user cannot turn off all banks. There must be at least one
active bank.
MANUALLY SELECTING A CHANNEL
A specific channel can be continuously monitored without scanning. This is
useful if there is an emergency broadcast on a channel and the user wants
to hear all the details (even though there might be periods of silence) or
if the user wants to monitor only a specific channel or a locked-out
channel.
To manually select a channel, press MANUAL, enter the channel number, then
press MANUAL again.
If scanning has stopped at the desired channel, simply press MANUAL once.
Repeatedly press MANUAL to step through the channels one at a time.
LISTENING TO THE WEATHER BAND
The FCC (Federal Communications Commission) has allocated 11 channels for
use by the National Oceanic and Atmospheric Administration (NOAA).
This scanner is preprogrammed with the following frequencies available to
NOAA:
162.425 MHz 162.500 MHz
162.440 MHz 162.525 MHz
162.450 MHz 162.550 MHz
162.475 MHz
To hear a local forecast and regional weather information, simply press WX.
WX appears on the display.
The scanner scans through the weather band and stops on an active
broadcast. If a broadcast is weak, press WX again to continue to scan
through the weather band.
SPECIAL FEATURES
DESIGNATING A PRIORITY CHANNEL
By designating a priority channel, the user can scan through the programmed
channels and still not miss an important or interesting call on a specific
channel.
NOTE: Users can select only one channel as the priority channel.
To program a stored channel as the priority channel, press PGM, the desired
channel number, then PRI/HYPER SEARCH. P appears on the display.
To turn on the priority feature, press PRI/HYPER SEARCH during scanning.
PRIORITY appears on the display. The scanner now checks the priority
channel every 2 seconds, and stays on the channel if there is activity. P
appears on the display whenever the scanner is set to the priority channel.
To turn off the priority feature, press PRI/HYPER SEARCH until PRIORITY
disappears from the display.
USING THE 2-SECOND DELAY
Many agencies use a two-way radio system that might have a period of
several seconds between a query and a reply. To avoid missing a reply, a
2-second delay can be programmed into any channel. When the scanner stops
on an active channel with a programmed delay, it continues to monitor the
channel for 2 seconds after the activity stops before resuming scanning.
To program a 2-second delay into a specific channel, manually select the
desired channel then press DLY. DELAY appears on the display.
To program a 2-second delay when the scanner stops on an active channel
during scanning, quickly press DLY while the channel is still active.
DELAY appears on the display.
To turn off the programmed delay on any active channel, press DLY while the
channel is still active. DELAY disappears from the display.
LOCKING OUT CHANNELS
A scanner can be set to scan more efficiently by locking out channels the
user does not want to monitor. This is handy for locking out channels
where a frequency with a continuous transmission, such as a weather
channel, has been stored.
To lock out a channel, press MANUAL, enter the desired channel number,
press MAN or PGM to select the channel, then press L/O/SEARCH SKIP so
LOCKOUT appears on the display.
NOTES: Locked out channels can still be manually selected.
The user cannot lock out all channels. There must be at least one
active channel in each bank.
To unlock a channel, manually select the channel, then press L/O/ SEARCH
SKIP so LOCKOUT disappears from the display.
To unlock all channels, while the scanner is scanning, select the banks
containing the locked channels to be unlocked, press MANUAL, then press and
hold L/O/SEARCH SKIP until the scanner beeps twice.
CHANGING SCANNING AND SEARCH SPEEDS
The PRO-2040 has two scan and three search speeds.
Type Speed
Normal Scan 12 channels/second
Hyper Scan 50 channels/second
Normal Search 50 steps/second
High Speed Search 100 steps/second
Hyper Search 300 steps/second
To change the scanning speed, during scanning, press SPEED to switch
between normal and hyper scan speeds. SCAN flashes on the display during
hyper scan speed.
NOTES: Scan speeds can also be changed when listening to the weather band.
UP or DOWN TRIANGLE flashes on the display during hyper scan.
To change the search speed, during a limit or direct search, press SPEED to
switch between the normal and high speed search speeds. UP or DOWN
TRIANGLE flashes on the display during high speed search.
To select the hyper search speed, during a limit or direct search, press
PRI/HYPER SEARCH. SEARCH flashes on the display during hyper search speed.
NOTE: Hyper search speed can only be used in 5kHz-step bands.
SKIPPING DATA SIGNALS
The scanner can be set to skip data signals (nonmodulated signals such as
preamble signals for pagers) during a limit or direct search.
NOTE: Data signals in the air band (AM mode) cannot be skipped.
To skip data signals, press DATA so DATA appears on the display. The
scanner might pause momentarily at an unwanted signal but resumes searching
in 2 or 3 seconds.
To stop skipping data signals, press DATA so DATA disappears from the
display.
