Using The Reset Button

Before using the scanner the first time we recommend you reset the scanner
to remove any random frequencies that might be stored in its channels.
Also, the scanner's display might lock up the first time you connect power
to it, or if there are no batteries installed for an extended period.

To reset the scanner, turn on the scanner, hold down CLEAR and use a
ball-point pen or similar object to press the RESET switch in the battery
compartment. This clears all programmed channels from the scanner.  Use
this procedure only when you are certain the scanner is not working
properly.

Setting The Volume and Squelch Controls

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 signals.

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 LIGHT, VOLUME, SQUELCH, MANUAL and SCAN on top of the
scanner.

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

2.  Enter a frequency.

    A good reference for active frequencies is RadioShack's Police Call
    Directory including Fire and Emergency Services.

    We update this directory 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.  If you want the scanner to pause 2 seconds after each transmission
    before scanning to the next channel, press DELAY so that DLY appears
    in the display.  See "Using the Delay Feature."

5.  Repeat Steps 1-4 to program more channels.  If you want to program the
    next channel in sequence, press PGM and repeat Steps 2-4.

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 this manual.

Limit Search

This procedure lets you search within a range of frequencies.  -L- appears
on the display during a limit search.

Notes: Pressing SPEED switches between the 8 steps per second and 50 steps
       per second search speed.

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

1.  Press PGM.  Then, press LIMIT.

2.  Enter the lower limit of the frequency range.

3.  Press ENTER.  Then, press LIMIT.

4.  Enter the upper limit of the frequency range.

5.  Press ENTER.

6.  Press \/ to search down from the upper limit.  Or, press /\ to search
    up from the lower limit.

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 \/ or /\ to continue the search.

Direct Frequency Search

When you are listening to a channel, you can search up or down from the
current frequency.  -d- appears in the display during a direct frequency
search.

1.  Press MANUAL and the channel number to select a channel in which you
    have programmed a frequency.  Then, press either MANUAL or PGM.

2.  Press /\ to search up from the channel's frequency or press \/ to
    search down.

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

    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 and then the number for the monitor
    memory you want to listen to.

Moving A Frequency From Monitor Memory To A Channel

To move a frequency from a monitor memory to a channel memory, 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 memory number that has the frequency
    you want to store.

3.  Press ENTER.

    The scanner stores the monitor frequency in the channel.

    If you want to return to a limit search after this procedure, press
    LIMIT, and either /\ or \/ to continue.

Scanning The Channels

To begin scanning, press SCAN.  The scanner scans through all non-locked
channels in the activated banks.  You must set SQUELCH so that you do not
hear the hissing sound between transmissions.  Be sure to read the
following sections to get the full benefit from all of your scanner's
special features.

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 operating this way.

To program a delay, select the channel and press DELAY so that DLY appears
on the display.  Now, when your scanner pauses at an active channel when
scanning, it waits for 2 seconds after the completion of each transmission
on that channel before it resumes 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 have 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 scanner has two different scanning speeds - 8 channels/second and 25
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
you have not programmed.  Manually select the channel and press L/OUT so
that L/O appears on the display.  This is also handy for locking out
channels that have a continuous transmission. You can still manually
select locked-out channels.

To unlock a channel, manually select the channel and press L/OUT so that
L/O disappears from the display.

Note: There must be at least one active channel in each bank.  You cannot
      lockout all channels.

Turning Banks On and Off

As explained in "Understanding Channel Storage Banks" the scanner splits
the 200 channels into ten banks of 20 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.  When you turn off a bank, the scanner
does not scan any channel in the bank.  While scanning, 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 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.

You can still manually select any channel in a bank, even if the bank is
turned off.  You cannot turn off all banks.  One bank is always active.

Using the Priority Feature

You can scan through the programmed channels, and still not miss an
important or interesting call 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 now checks the priority channel
every 2 seconds, and stays on the channel if there is activity.

To program a channel as the priority channel, press PGM, the desired
channel number and then press 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.

Manually Selecting A Channel

You can monitor a 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 locked-out channel.

To select a channel, just press MANUAL, enter the channel number and press
MANUAL again.  Or, if the scanner is scanning and stops at the desired
channel, just press MANUAL one time.  Pressing MANUAL additional times
makes the scanner step through the channels.

Battery-Saving Feature

Your scanner has a special battery saving feature.  When you have manually
selected a channel, if the scanner does not detect a signal within 5
seconds and you do not press a key, the scanner enters the standby mode.
In this mode the scanner rests for 1 second, then checks for a signal for
1/2 second.  The scanner continues doing this until you press a button or
it receives a signal.

During standby, the scanner uses only 40 percent of the normal power
consumption.
