PRO-34 Programmable Scanner
(200-0135)                 Operation                  Faxback Doc. # 48553

PROGRAMMING THE PRO-34

1.  Select a channel to program by pressing [MANUAL], entering the channel
    number you want to program, the pressing [PGM].

    "PGM" appears in the display to indicate the PRO-34 is in the
    programming mode.

2.  Enter a frequency.

    A good reference for active frequencies is RadioShack's Police Call
    Directory including Fire and Emergency Services.  This is updated
    yearly, so be sure to get a current one.  Also, refer to "Reception
    Notes" in Faxback Doc. # 17653 and "Searching for Active Frequencies"
    below.

3.  Press [ENTER].

    The frequency is entered.  If you made a mistake in Step 2, the
    display shows "Error" and a beep sounds.  Press [CLEAR] and proceed
    again from Step 2.

4.  Press [DELAY].

    If you want the PRO-34 to pause after each transmission before
    scanning to the next channel, press [DELAY] so that "DLY" appears in
    the display.  If you do not want the PRO-34 to pause, ensure "DLY" is
    not in the display.

5.  Repeat Steps 1-4 to program more channels.

   Note that if you want to program the next channel in sequence, just
   press [PGM] and proceed to Step 2.

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.  See also "Guide to
the Action Bands" in Faxback Doc. # 17653.

Limit Search

This procedure allows you to search within a range of frequencies.  "-L-"
appears in the display during a limit search.

1.  Press [PGM].

2.  Press [LIMIT].

3.  Enter the lower limit of the frequency range.

4.  Press [ENTER].  Then press [LIMIT].

5.  Enter the upper limit of the frequency range.

6.  Press [ENTER].

7.  Press [\/] to search from the upper limit down to the lower limit.
    Or, press [/\] to search upward starting from the lower limit.

8.  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 flickering.  Or press [\/] or [/\] to continue the
    search.

Notes:  Pressing [SPEED] speeds up or slows down the search.

        Press [DLY] to make the scanner pause 2 seconds after a
        transmission before proceeding to the next frequency.

Direct Frequency Search

When you are in the program or manual listening mode, you can search up or
down from the current frequency.  "-d-" appears in the display during a
direct frequency search.

1.  Select a currently programmed channel by pressing [MANUAL], the
    channel number, then either [MANUAL] or [PGM].

2.  Press [/\] to search through higher frequencies or [\/] to search
    through lower frequencies.

3.  When the scanner stops on a transmission, you can store that frequency
    into a monitor memory by pressing [MON].

MOVING A FREQUENCY FROM MONITOR MEMORY TO A CHANNEL

As you store frequencies in monitor memories, the bar under the memory
number indicates the current monitor memory.  You can listen to monitor
memories by pressing [MANUAL], [MON], then the number of the monitor
memory you wish to listen to.

If there is a frequency you wish to store in a channel, follow this
procedure to move it from the monitor memory.

1.  Press [MANUAL], the channel number you wish the frequency to be stored
    in, then [PGM].

2.  Press [MON], then the monitor memory number you wish to move.

3.  Press [ENTER].

    The frequency is stored in the channel.

If you want to return to a limit search after this procedure, press
[LIMIT], then either the [/\] or [\/] button to continue.

USING THE RESET BUTTON

The scanner's display might lock up the first time you connect power to
it, or if the batteries are left out for an extended period of time.
If this occurs, hold down [CLEAR] and use a sharp instrument to press the
reset switch in the battery compartment while power is on.  This procedure
clears any information you have programmed into the scanner.  Use this
procedure only when you are certain the unit is not working properly.

SETTING THE VOLUME AND SQUELCH

Rotate VOLUME clockwise and SQUELCH counterclockwise until you hear a
hissing sound.  Then, slowly rotate SQUELCH clockwise until the noise
stops.  Leave VOLUME set to a comfortable level.

If the scanner picks up unwanted weak transmissions, rotate SQUELCH
clockwise to decrease the scanner's sensitivity to these signals.

USING THE KEY LOCK

Once you have finished programming your PRO-34, you can protect it from
accidental program changes by moving KEY LOCK to LOCK.  In this position,
only controls that work are [LIGHT], [MANUAL] and [SCAN] on top of the
scanner, VOLUME, and SQUELCH.  All other controls are locked, so that
entries are not possible.

When you want to change the programming of your PRO-34, just move the
switch to KEY.

SCANNING THE CHANNELS

To begin scanning, just press [SCAN].  The PRO-34 scans through all
channels in the activated banks that are not locked out.  SQUELCH must be
set so that the hissing sound is not heard between transmissions.  Be sure
to read all of the following sections to get the full benefits from all of
the special features of your scanner.

USING THE DELAY FEATURE

Many agencies use a two-way radio system that might have a period of
several seconds between a query and a reply.  To keep from missing a
reply, program a delay on the channels you identify as having this type of
operation.  Just manually select the channel, and press [DELAY] so that
"DLY" appears in the display.  Now, when you are scanning through
channels, the PRO-34 pauses for two seconds after the completion of each
transmission on that channel before resuming scanning.

Some radio systems, notably 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 that the
query can be on one frequency and the reply on another.  To ensure the
best possibility of hearing the full reply, you want the scanner to begin
scanning immediately when the first transmission ends.  In this case,
manually select the channel and ensure that "DLY" is not in the display.
If it is, press [DELAY] to turn off this feature for that channel.

SETTING THE SCANNING SPEED

The PRO-34 has two different scanning speeds - 4 channels/second and 8
channels/second.  To switch between the two scanning speeds, press [SPEED]
during scanning.

LOCKING OUT CHANNELS

You can increase the effective scanning speed by locking out channels that
are not programmed.  Manually select the channel, and press [L/OUT], so
that "L/O" appears in the display.  This is also handy for locking out
channels that have a continuous transmission, such as a weather channel.
You can still manually select locked-out channels for listening.

To disable the lockout function, manually select the channel and press
[L/OUT].

Note:  You can lock out as many channels as you like.  But there must be
       at least one channel that is not locked out in each bank.

TURNING BANKS ON AND OFF

As explained in "Understanding Channel Storage Banks" the PRO-34 splits
the 200 channels into ten banks of twenty channels each.  The small bars
under the numbers at the top of the display are the bank indicators.  You
can turn each bank on and off, so that all of the channels in a bank are
either scanned or locked out.  In scan mode, press the number key
corresponding to the bank you want to turn on or off.  If the memory bank
indicator is on, the bank is turned on and all channels within that bank
that are not locked out are scanned.  If the indicator is off, none of the
channels within that bank are scanned.  You can still manually select any
channel in a bank, even if the bank is turned off.  You cannot turn off
all banks - one must be on.

USING THE PRIORITY FEATURE

You can scan through all of your programmed channels, and still not miss
an important or interesting call on a specific channel.  Simply program
the channel as the priority feature by pressing [PRI] during scanning.
The scanner now checks the priority channel every two seconds, and stays
on the channel if there is activity.

To program a priority channel, simply press [PGM], the desired channel
number, then [PRI].  "P" appears in the upper left corner of the display
whenever the scanner is set to the priority channel.  Only one channel
can be programmed as the priority channel.

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 of the details-even though there might be periods of silence-or
if you want to monitor a channel that has been locked out.  To select a
channel, just press [MANUAL], enter the channel number, then press
[MANUAL] again.  Or, if the PRO-34 is scanning and has stopped at the
desired channel, just press [MANUAL] one time.  Pressing [MANUAL]
additional times causes the PRO-34 to step through the channels one at a
time.
