SETTING THE VOLUME AND SQUELCH

Follow these steps to set the volume and squelch.

1.  Set VOLUME to about 2 and SQUELCH to 10.

2.  Slowly turn SQUELCH counter-clockwise until you hear a hissing sound.

3.  Adjust VOLUME to a comfortable sound level.

4.  Slowly rotate SQUELCH clockwise until the hissing stops.

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

Storing Frequencies

Follow these steps to store frequencies in channels:

1.  Press [MANUAL].  Enter the channel number you want to program.

2.  Press [PROGRAM]. PGM appears on the display.

3.  Enter a frequency.

4.  Press [ENTER] to store the frequency.  If you make a mistake in Step
    3, ERROR appears on the display.  Press [CLEAR] and repeat Step 3.

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

SEARCHING FOR AND TEMPORARILY STORING ACTIVE FREQUENCIES

Good references for active frequencies are Radio Shack's "Police Call 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.

If you do not have a reference to frequencies in your area, use these
procedures to search for a transmission.  See also "A Guide to the Action
Bands" in this manual.

NOTE:  Press [DELAY] to make the scanner pause 2 seconds after a
       transmission ends before proceeding to the next frequency.

LIMIT SEARCH

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

1.  Press [PROGRAM], then [LIMIT].

2.  Enter the lower limit of the frequency range.

3.  Press [ENTER], then [LIMIT].

4.  Enter the upper limit of the frequency range.

5.  Press [ENTER].

6.  Press [UP-ARROW] to search up from the lower limit.  Or, press [DOWN-
    ARROW] to search down from the upper limit.

7.  When the scanner stops on a transmission, press [MONITOR] to store the
    frequency in the current monitor memory, or press [UP-ARROW] or [DOWN-
    ARROW] to continue the search.

NOTE:  As you store frequencies in monitor memories, the bar under the
       memory number indicates the current monitor memory.

DIRECT SEARCH

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

1.  Press [MANUAL] and the channel number to select a channel in which you
    have programmed a frequency.  Then press [MANUAL] or [PROGRAM] to enter
    the channel number.

2.  Press [UP-ARROW] to search up from the channel's frequency or press
    [DOWN-ARROW] to search down.

3.  When the scanner stops on a transmission, press [MONITOR] to store that
    frequency in the current monitor memory.

LISTENING TO MONITOR MEMORIES

You can listen to monitor memories by press [MANUAL], [MONITOR], and then
the number for the monitor memory you want to listen to.

MOVING A FREQUENCY FROM A MONITOR MEMORY TO A CHANNEL

Follow these steps to move a frequency from a monitor memory to a channel.

1.  Press [MANUAL].  Enter the channel number you want to store the monitor
    frequency in; then press [PROGRAM].

2.  Press [MONITOR] 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 [UP-ARROW] or [DOWN-ARROW] to continue.

SCANNING THE CHANNELS

To begin scanning the channels, press [SCAN].  Your scanner scans through
all non-locked channels in the activated banks.  Set SQUELCH so that you do
not hear hissing sounds between transmissions.

Be sure to read the following sections to get the full benefits from all of
your scanner's special features.

USING THE DELAY FEATURE

Many agencies use a two-way radio system that might have a pause of several
seconds between a query and a reply.  To program a delay into that channel
to keep from missing a reply, select the channel and press [DELAY] so DELAY
appears on the display.

When your scanner pauses at an active channel which has been programmed
with a delay, while scanning, it waits for 2 seconds after the completion
of each transmission on that channel before it resumes scanning.

SCANNING AND SEARCH SPEEDS

While you are in scan or search mode, you can press [SPEED] to select the
scanning/search speed.

The scanner has 2 different scanning speeds:

* 8 channels per second
*25 channels per second

It also has 2 different search speeds:

* 8 steps per second
*50 steps per second

LOCKING OUT CHANNELS

You can increase the effective scanning speed by locking out specific
channels that you have not yet programmed.  Manually select the empty
channel and press [LOCK OUT] so that L/OUT appears on the display.  This is
also handy for locking out channels you have programmed that have a
continuous transmission.  You can still manually select locked-out
channels.

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

NOTE:  There must be at least one active channel in each bank.  You cannot
       lock out all channels.

PRIORITY

You can scan through the programmed channels, and still not miss an
important or interesting call on a specific channel.  To program a stored
channel as the priority channel, press [PRIORITY], the desired channel
number and then [PRIORITY].  You can only select one channel as the
priority channel.

To turn on the priority feature, press [PRIORITY] during scanning.  PRI
appears on the display.  The scanner now checks the priority channel every
two seconds, and stays on the channel if there is any activity.  P appears
in the upper left corner of the display whenever the scanner is set to the
priority channel.

To turn off the priority feature, press [PRIORITY] until PRI disappears
from the display.

MANUALLY SELECTING A CHANNEL

You can continuously monitor a specific 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 only a locked-out channel.

Follow these steps to manually select a channel.

1.  Press MANUAL.

2.  Enter the channel number.

3.  Press MANUAL again.

Or, if the scanner is scanning and stops at the desired channel, press
MANUAL one time.  (Pressing MANUAL additional times causes the scanner
to step through the channels.)
