2.  Press RESET using a ball point pen or something similar to that.

To clear memory and initialize the unit

1.  Turn on the scanner.

2.  Press and hold CLEAR.

3.  Press RESET and release.

4.  Press CLEAR after the display disappears.

Setting the Volume and Squelch

Follow these steps to set the VOLUME and SQUELCH.

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

2.  Slowly turn [SQUELCH] counterclockwise until you hear a hissing noise.

3.  Adjust [VOLUME] to a comfortable sound level.

4.  Slowly rotate [SQUELCH] clockwise until the hissing noise 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.  Press
    [MANUAL] again.

2.  Press [PROGRAM] to enter the programming mode.  'PROGRAM' appears on
    the display.

3.  Enter the desired frequency. 

4.  Press the [ENTER] key to store the frequency.

NOTE:  If you made a mistake in Step 3, ERROR appears on the display.
Press [CLEAR] and repeat Step 3.

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

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

LIMIT SEARCH

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

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

2.  Enter the lower limit of frequency range to be searched.

3. Press [ENTER]. Press [LIMIT] key again. 

4.  Enter the upper limit of frequency range to be searched.

5.  Press [ENTER].

6.  Press [down arrow] to search from the highest frequency and go down or
    press [Up arrow] to search from the lowest frequency and go up.

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 number to the
right of 'MON' 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 pressing [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, press [SCAN].  The scanner scans through all non-locked
channels in the activated banks.  Set SQUELCH so you do not hear the
hissing sound between transmissions.

SPECIAL FEATURES

DELAY

Many agencies use a two-way radio system that might have a period 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 when scanning, it waits for two seconds after the completion
of each transmission on that channel before it resumes scanning.

LOCKING OUT CHANNELS

You can increase the effective scanning speed by locking out specific
channels that you have not yet programmed.  Manually select the channel and
press [LOCK OUT] so that 'LOCKOUT' 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 that is locked out and
press [LOCK OUT] once so LOCKOUT disappears from the display.

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

TURNING CHANNEL-STORAGE BANKS ON AND OFF

You can turn each channel-storage bank on and off.  When you turn off a
bank, the scanner does not scan any of the 5 channels 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 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.

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 [PROGRAM], the desired channel
number and then press [PRIORITY].  You can only select one channel as the
priority channel.

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

To turn off the priority feature, press [PRIORITY] until 'P' 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.

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.

LISTENING TO THE WEATHER BAND

The FCC (Federal Communications Commission) has allocated several channels
for use by the National Oceanic and Atmospheric Administration (NOAA).  We
have preprogrammed your scanner with all of the frequencies available to
NOAA.  To hear your local forecast and regional weather information, simply
press [WX].  Your scanner scans through the weather band.

Your scanner should stop within a few seconds, and you hear the local
weather broadcast.  If the broadcast is weak, you can press [WX] again to
scan through the rest of the weather band.
