TURNING ON THE SCANNER AND SETTING SQUELCH
1. Turn SQUELCH fully counterclockwise before you turn on the scanner.
2. Turn VOLUME clockwise until you hear a hissing sound.
3. Turn SQUELCH clockwise, just until the hissing sound stops.
Note: To listen to a weak or distant station, turn SQUELCH
counterclockwise . If reception is poor, turn SQUELCH clockwise to
cut out weak transmissions.
SEARCHING FOR AND STORING ACTIVE FREQUENCIES
Your scanner can store up to 51 frequencies. Each frequency can be stored
in either a memory called a channel, or the temporary memory called a
monitor. This scanner has 50 channels and one monitor memory.
You can store frequencies using any of these methods.
Manually enter and store a specific frequency.
Search for active frequencies within a range of preprogrammed
frequencies and store selected frequencies in the scanner's channel
memories.
Search for active frequencies starting directly from one specific
frequency and store a frequency in the scanner's monitor memory.
Recall the monitor memory frequency and move that frequency to a
channel memory.
Active Frequency References
Good references for active frequencies are RadioShack's Beyond Police Call,
Police Call Radio Guide Including Fire and Emergency Services, Aeronautical
Frequency Directory, and Radio! magazine. We update these references often,
so be sure to get a current copy.
If you do not have a reference to frequencies in your area, or if you want
to search for unlisted frequencies, use a band search or direct search.
See "General Guide to Scanning," Faxback Doc. # 39173.
Storing Frequencies
Follow these steps to store frequencies into your scanner's channels.
1. Press PGM. PGM appears on the display to indicate the scanner is in
the programming mode.
2. Use the number keys to enter the channel number (1-50) where you want
to store the frequency, then press PGM again. Or, repeatedly press
PGM until the desired channel number appears.
Notes:
If you enter an invalid channel number, Error appears on the display.
Simply repeat this step.
If a frequency is currently stored in the selected channel, the channel
number does not flash but the current frequency number appears on the
display. You can either repeat this step to select a different channel,
or replace the current frequency with a new one.
3. Use the number keys and./DLY to enter the frequency (including the
decimal point) you want to store in that channel.
4. Press E/L-OUT to store the frequency. The selected channel number stops
flashing, indicating that the selected channel is stored.
Notes:
If you entered an invalid frequency in Step 3, Error appears on the
display after you press E/L-OUT. Simply repeat Steps 3 and 4 and enter
a valid frequency in Step 3.
Your scanner automatically rounds the entered frequency down to the
nearest valid frequency. For example, if you try to enter a frequency
of 151.4730, your scanner accepts it as 151.4700.
If you entered a frequency that is already stored in another channel,
dUPL (duplicate) and the lowest-numbered channel containing the
duplicate frequency flash on the display for about 3 seconds.
To store the duplicate frequency, press E/L-OUT again. To store a
different frequency, repeat Steps 3 and 4, and enter a different
frequency in Step 3.
5. Repeat Steps 2-4 to program another channel.
Using Band Search
If you do not know of a frequency to store, you can search your scanner's
preprogrammed search bands for active frequencies, then store any that you
find into your scanner's channels.
Follow these steps to search for and store active frequencies using band
search.
1. Press BAND. The last selected band number (b followed by a number,
such as b2) and the associated frequency search range appear on the
display.
2. To select a different band, within 2 seconds, enter the desired band
number, or repeatedly press BAND until the desired band number appears
on the display. After about 2 seconds, SRCH appears, the next
available channel flashes, and the scanner begins searching rapidly
upward in that band (from lowest to highest frequency) for an active
frequency.
Notes:
To select a different band after the scanner begins searching the current
band, simply repeat this step.
To reverse the rapid search direction at any time, press and hold up or
down arrow for about 1 second.
To search the selected band upward or downward in small increments (in
steps of 5 or 12.5 kHz, depending on the band), press and release arrow
up or down so that an arrow disappears from the display.
3. When the scanner finds an active frequency, it stops scanning and
displays that frequency's number. To store that frequency in the
channel currently flashing on the display, simply press E/L-OUT. The
scanner stores the frequency, then the next available channel flashes
on the display.
Notes:
You cannot store an active frequency in the monitor memory during band
search.
After you store a frequency into the last available channel, --ch appears
instead of a channel number. If you try to store another channel while
--ch appears on the display, Ch FULL appears briefly on the display. In
order to store more frequencies, you must clear some channels.
4. To search for another active frequency in the selected band, press and
hold arrow up or down for about 1 second, then repeat Step 3.
To select a different band then search for another active frequency,
repeat Steps 2 and 3.
Using Direct Search
During a direct search, the scanner searches upward or downward, starting
from a frequency you specify. Follow these steps to use direct search.
1. Press MANUAL or PGM, then enter the frequency you want to use as a
starting point for the search.
Note: To start from a frequency already stored in one of your
scanner's channels, press MANUAL or PGM, enter the desired
channel number, then press MANUAL or PGM again.
2. Press and hold up or down arrow for about 1 second to search upward or
downward. -d, SRCH, and up or down arrow appear on the display.
3. When the scanner stops on an active frequency, you can either:
Press 0/MON to store it in the monitor memory.
Press and hold up or down arrow to continue the search.
USING THE MONITOR MEMORY
After you store a frequency in the scanner's monitor memory during a direct
search, you can recall it and move it to one of your scanner's channel
memories.
Listening to the Monitor Memory
To recall a frequency stored in the monitor memory, simply press MANUAL
then 0/MON. MAN then MON and the stored frequency appear on the display.
Moving a Frequency from the Monitor Memory to a Channel
1. Press MANUAL, enter the channel number where you want to store the
frequency, then press PGM. PGM and the selected channel number appear
on the display.
2. Press MON. MON and the monitor memory frequency appear on the display.
3. Press E/L-OUT. MON disappears, the channel number stops flashing, and
the frequency is stored in the selected channel.
SCANNING THE STORED CHANNELS
To set the scanner to continuously through all channels with stored
frequencies, simply press SCAN. SCAN and up arrow appear on the display,
and the scanner begins to rapidly scan upward until it finds an active
frequency.
If the scanner finds an active frequency, it stops and displays that
channel and frequency number, then it automatically begins scanning again
when the transmission ends on that frequency.
Notes:
To reverse the scanning direction, press arrow up or down.
To set the scanner to remain on the current channel for 2 seconds after
the transmission ends, see "Special Features," Faxback Doc. # 38547.
To set the scanner to remain on the current channel, even after the
transmission stops, press MANUAL at any time during the transmission so
MAN appears and SCAN disappears from the display.
To lock out channels so the scanner does not stop for a transmission on
those channels.
MONITORING A STORED 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 simply want to monitor that channel.
Follow these steps to manually select a channel.
1. Press MANUAL.
2. Enter the channel number.
3. Press MANUAL again.
CLEARING A STORED CHANNEL
If you no longer want a frequency stored in a channel (and you do not want
to replace that frequency with a different one), follow these steps to
clear the stored frequency.
1. Select the channel that you want to clear.
2. Press PGM. PGM appears on the display.
3. Press CLEAR. The frequency number flashes on the display.
4. Press E/L-OUT. L/O (lockout) appears, the channel number flashes, and
the frequency number changes to 000.0000 on the display to indicate
the channel is cleared.
5. To clear another channel, use the number keys to enter that channel
number (1-50), then press PGM again. Or, repeatedly press PGM until
the desired channel number appears. Then repeat Steps 3-4.
