PRO-43 (200-0300) Operation Faxback Doc. # 16688
A LOOK AT THE DISPLAY
The display has several indicators that show the scanner's current
operating mode. A quick look at the display will help you understand the
scanner's operation.
The following is a brief explanation of each scanner indicator.
P - appears when you tune to the priority channel.
MON - appears when you tune to a monitor memory.
BANK - bars to the right of this indicator show which memory banks are
turned on for the scan mode. See "Understanding Channel
Storage Banks."
CH - digits that precede this indicator show the selected channel.
FM or AM - appears to indicate the search direction in the search mode and
to indicate the scanning direction in the program, scan, and
manual modes.
[up] or - appears to indicate the search direction in the search mode and
[down] to indicate the scanning direction in the program, scan, and
arrow manual modes.
SRCH - appears during a limit search (-L- also displayed) or a direct
frequency search (-d- also displayed).
SCAN - comes on when you scan channels.
MAN - comes on when you manually select a channel.
PGM - appears while you program frequencies into the scanner's
channels.
PRI - appears when you turn on the priority channel feature.
DLY - appears when the scanner is set to a channel programmed with
the delay feature. See "Programming a Scan Delay."
L/O - appears when the channel you listen to is locked out of the
scan mode. See "Locking Out Channels."
When the entire display blinks and the scanner beeps every 2 seconds, the
batteries are low.
A LOOK AT THE KEYBOARD
The scanner's keys might seem confusing at first, but a quick glance at
this page and the next should help you understand each key's function.
KEY LOCK - disables the keypad to prevent accidental program changes.
Number Keys - have a single digit, followed by a range of numbers. The
single digit is the number entered when you enter a channel
number or a frequency. The range of numbers (21-40, for
example) indicates the channels that make up a channel
storage bank. See "Understanding Channel Storage Banks."
SCAN - makes the scanner through the programmed channels.
MANUAL - stops scanning and lets you directly enter a channel
number.
PRI - turns the priority feature on and off.
LIMIT - turns on the limit mode and sets the frequency range. See
"Searching for Active Frequencies."
L/OUT - turns the lockout function on and off for the selected
channel.
[up] & [down] - selects the search, program, scan, or manual mode
arrow direction.
DELAY - turns the delay feature on and off for the selected
channel.
./DIRECT - enters a decimal point after numbers and searches
frequencies beginning at the displayed frequency.
ENTER - stores a frequency in channel.
LIGHT - turns on and off the display light.
MON - accesses the 10 monitor memories. See "Searching for
Active Frequencies."
AM/FM - switches the scanner to AM or FM mode.
PGM - sets the scanner so you can store frequencies in channels.
CLEAR - clears an incorrect entry.
RESETTING THE SCANNER
When you first power the scanner, or if no batteries are installed for an
extended period of time, its display might lock up and the channels might
contain random frequencies. We recommend you reset the scanner before you
begin using it.
To reset the scanner, hold down both CLEAR and 0, and turn on the power.
This clears all programmed channels from the scanner. Use this procedure
only when you are sure the scanner is not working properly.
SETTING THE VOLUME AND SQUELCH CONTROLS
Turn SQUELCH counterclockwise and VOLUME clockwise until you hear a hissing
sound. Then slowly turn SQUELCH clockwise until the noise stops. Leave
VOLUME set to a comfortable level.
If the scanner picks up unwanted weak transmissions, turn SQUELCH clockwise
to decrease the scanner's sensitivity to these signals.
If you want to hear a weak or fading transmission, turn SQUELCH
counterclockwise. You hear hiss between transmissions, but this prevents
the scanner from cutting off weak transmissions.
USING THE KEY LOCK
Once you program your scanner, you can protect it from accidental program
changes by moving KEY LOCK to LOCK. In this position, the only controls
that operate are SCAN, MANUAL, LIGHT, VOLUME, and SQUELCH.
When you want to change the scanner's programming, move the switch to KEY.
PROGRAMMING THE SCANNER
Follow these steps to store frequencies in channels.
1. Press MANUAL. Enter the channel number you want to program, the press
PGM. PGM appears on the display to indicate the scanner is in the
programming mode.
2. Enter a frequency.
Good references for active frequencies are Radio Shack's "Police Call
Radio Guide including Fire and Emergency Services," "Official
Aeronautical Frequency Directory," and "Maritime Frequency Directory."
We update these directories every year, so be sure to get a current
copy. Also, refer to "Reception Notes" and "Searching for Active
Frequencies" in this manual.
3. Press ENTER to store the frequency.
If you made a mistake in Step 2, ERROR appears on the display. Press
CLEAR and repeat Step 2.
4. Press AM/FM to set the receive mode to the correct setting for the
frequency. See "Changing AM/FM Mode."
5. If you want the scanner to pause 2 seconds after each transmission
before scanning to the next channel, press DELAY so DLY appears in the
display. See "Programming a Scan Delay."
6. Repeat Steps 1-5 to program more channels. To program the next channel
in sequence, press PGM and repeat Steps 2-5. To change the programming
direction, press [up] or [down] arrow before you press PGM.
SEARCHING FOR ACTIVE FREQUENCIES
Use these procedures to search for a transmission. This is helpful if you
do not have a reference to frequencies in your area. Also see "Guide to
the Action Bands."
Limit Search
This procedure lets you search within a range of frequencies. -L- appears
on the display during a limit search.
1. Press PGM.
2. Press LIMIT.
3. Enter the lower limit of the frequency range. Then press ENTER.
4. Press LIMIT.
5. Enter the upper limit of the frequency range. Then press ENTER.
6. Press [up] or [down] arrow to search down or up within the specified
range.
7. When the scanner stops on a transmission, press MON to store the
frequency in the current monitor memory - the bar under the memory
number stops flashing. Or press [up] or [down] arrow to continue the
search.
NOTE: Press DELAY to make the scanner pause 2 seconds after a transmission
before it proceeds to the next frequency.
Direct Search
When you listen to a channel, you can search up or down from the displayed
frequency. -d- appears in the display during a direct search.
1. Press MANUAL, the channel number, and MANUAL in sequence to select a
frequency stored in a channel. Then press ./DIRECT.
2. Press [up] or [down] arrow to search up or down from the selected
frequency.
3. When the scanner stops on a transmission, you can store that frequency
in the current monitor memory by pressing MON. Or press [up] or [down]
arrow to continue search.
NOTE: Press DELAY to make the scanner pause 2 seconds after a transmission
before it proceeds to the next frequency.
USING THE MONITOR FREQUENCIES
During a limit or direct search, the flashing bar under the memory number
indicates the current monitor memory. During a limit or direct search you
can store a frequency when the scanner stops on a frequency stored by
pressing MON. The scanner replaces any frequency stored in the monitor
memory with the tuned frequency, and advances to the next monitor memory.
To listen to a monitor memory, press (in sequence) MANUAL, MON, and number
for the monitor memory you want to listen to.
Moving a Frequency from a Monitor Memory to a Channel
To move a frequency from a monitor memory to a channel, follow these steps.
1. Press MANUAL, enter the channel number you want to store the monitor
frequency in, and press PGM.
2. Press MON and enter the monitor number that has the frequency you want
to store.
3. Press ENTER. The scanner stores the monitor frequency in the channel.
SCANNING THE CHANNELS
To begin scanning the channels, press SCAN. Press [up] or [down] arrow to
select the scan direction. (The scan direction is [up] arrow when you turn
on the power.) The scanner scans through all non-locked channels in the
activated banks. (See "Locking Out Channels" and "Turning Banks On and
Off.")
You must set SQUELCH so you do not hear the hissing sound between
transmissions for the scanner to scan.
CHANGING AM/FM MODE
We designed your scanner to automatically select the most common receive
mode for each frequency range. Default settings are shown below.
FREQUENCY (MHz) RECEIVE MODE
30.000 - 54.000 .................. FM
118.000 - 136.000 .................. AM
137.000 - 174.000 .................. FM
220.000 - 2250000 .................. FM
225.0125 - 400.000 .................. AM
400.0125 - 512.000 .................. FM
806.000 - 999.9875 .................. FM
Although the preset mode is correct in most cases, some ham radio and
military aircraft (225 - 400 MHz) broadcasts are not in the default mode.
If you try to listen to a broadcast when the scanner is not set to the
correct receive mode, the broadcast might sound weak or distorted.
To change the mode, press AM/FM. AM or FM blinks on the display when you
override the default mode.
If you press AM/FM during a limit search or direct search, the scanner
keeps searching for frequencies in the selected mode and AM or FM blinks on
the display. AM or FM blinks even if the mode of a frequency is the same
as the default setting. To return to the default settings, press AM/FM
while holding down CLEAR.
PROGRAMMING A SCAN DELAY
Many agencies use a two-way radio system with periods of several seconds
between each query and reply. To keep from missing a reply, program a
delay on the channels that operate this way.
To program a delay, select the channel and press DELAY so DLY appears on
the display. Now, when you scanner pauses on that channel when scanning,
it waits for 2 seconds after each transmission before it resumes scanning.
CANCELLING A SCAN DELAY
Some radio systems, especially those above 800 MHz, use a special trunked
system. In these systems, the transmitter selects an available frequency
each time the operator keys the radio. It is therefore possible for the
query to be on one frequency and the reply to be on another. In this case,
you have a better chance of hearing the full reply if the scanner
immediately resumes scanning when a transmission ends. For each channel
that operates this way, manually select the channel and ensure DLY does not
appear. If it does, press DELAY to turn off the delay for that channel.
LOCKING OUT CHANNELS
You can increase the effective scanning speed by locking out channels you
have not programmed. This is also handy for locking out channels that have
a continuous transmission. Manually select each channel and press L/OUT so
L/O appears on the display. You can still manually select locked-out
channels. To unlock a channel, manually select the channel and press L/OUT
so L/O disappears from the display.
NOTE: There must be at least one unlocked channel in each bank.
TURNING BANKS ON AND OFF
As explained in "Understanding Channel Storage Banks," the scanner splits
the 200 channels into 10 banks of 20 channels each. The small bars that
appear under the numbers at the top of the display when you scan are the
bank indicators.
When you turn off a bank, the scanner does not scan any channel in the
bank. To turn a bank on or off, while scanning press the number key
corresponding to the bank you want to turn on or off. Press 0 to turn on
or off Bank 10. If the 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 bank indicator is off, the scanner does not scan any of the channels
within that bank.
You can still manually select any channel in a bank, even if the bank is
turned off. You cannot turn off all banks.
USING THE PRIORITY FEATURE
The priority feature helps you avoid missing calls on a specific channel.
Just program the channel as the priority channel and turn on the priority
feature by pressing PRI during scanning. The scanner checks the priority
channel every 2 seconds, and stays on the channel if there is activity on
it.
To program a channel as the priority channel, press (in sequence) PGM, the
desired channel number, and PRI. P appears in the upper left corner of the
display whenever the scanner is set to the priority channel. You can only
select one channel as the priority channel.
To turn off the priority feature, press PRI again so that PRI disappears
from the display.
MANUALLY SELECTING A CHANNEL
To tune to a locked-out channel, or to remain tuned to a signal channel,
manually select the channel by pressing MANUAL, entering the channel
number, and pressing MANUAL again. Or, if the scanner is scanning and
stops at the desired channel, press MANUAL once. Press MANUAL additional
times to step through the channels.
You can use this feature to remain tuned to an emergency broadcast. During
regular scanning, the scanner tunes to other channels during periods of
silence.
If you want to change the direction of the step, press [up] or [down]
arrow before you press MANUAL.
BATTERY-SAVING FEATURE
When you manually select an inactive channel, the battery-saving feature
puts the scanner in standby mode, which uses only 30% of the normal power.
The scanner enters standby mode if it is manually set to a channel, it does
not receive a signal, and you do not press any button for 5 seconds. In
standby mode, the scanner rests for 1 second, checks for a signal for 1/4
second, and repeats the cycle until it receives a signal or you press a
button.
