DELAY
Many agencies use a two-way radio system that might have a pause of several
seconds between a query and a reply. Your scanner's delay feature lets it
wait for 2 seconds after each transmission on a channel or frequency while
scanning or searching.
To program a 2-second delay for a channel while scanning, manually select
the channel and press DELAY until DELAY appears. When your scanner stops
on the channel, it waits for 2 seconds after each transmission on that
channel before it resumes scanning.
To program a 2-second delay for any active frequency while searching, press
DELAY until DELAY appears. When your scanner stops on a transmission, it
waits for 2 seconds after each transmission on that frequency before it
resumes searching.
USING THE ATT switch
To reduce interference or noise caused by signals from a strong local
broadcaster, you can reduce the scanner's sensitivity to signals by setting
the ATT (attenuate) switch on the back of the scanner. Switch ATT to 10 dB
to reduce the scanner's sensitivity, or to 0 dB to increase it.
NOTE: If you switch ATT to 10 dB, your scanner might not receive weak
signals.
USING THE SOUND SQUELCH SWITCH
You can have the scanner skip frequencies that broadcast only a carrier
signal without an accompanying modulated (data or voice) signal by setting
the SOUND SQUELCH SWITCH on the front of the scanner. When SOUND SQUELCH
is turned on, the scanner continues scanning if it does not detect a
modulated signal on a frequency within 0.5 seconds.
NOTES: This feature works only while the scanner is scanning or searching,
or when monitoring the priority channel.
The sound squelch feature might not work properly if the monitored
frequency contains a transmission with a low modulated signal.
To set sound squelch, press SOUND SQUELCH until the scanner beeps and the
SOUND SQUELCH indicator turns on.
To turn off sound squelch, press SOUND SQUELCH again.
NOTE: If the scanner receives a frequency that broadcasts both a carrier
and a modulated signal, it stops scanning and monitors the
frequency.
If the modulated signal stops being broadcast on the frequency, the scanner
stays on the frequency for 5 seconds, then resumes scanning.
If the carrier signal stops being broadcast on the frequency, the scanner
resumes scanning immediately, unless DELAY is set.
LOCKING OUT CHANNELS AND FREQUENCIES
You can scan existing channels or search frequencies faster by locking out
channels or frequencies that have a continuous transmission, such as a
weather channel.
To lock out a channel while scanning, press L/OUT when the scanner stops
on the channel. To lock out a channel manually, manually select the
channel and press L/OUT until LOCK-OUT appears on the display.
To remove the lockout from a channel, manually select the channel and
press L/OUT until LOCK-OUT disappears from the display.
NOTES: You can delete the frequencies stored in locked-out channels within
a bank. See "Deleting Frequencies from All Locked-Out Channels
Within a Bank".
You can still manually select locked-out channels.
You cannot lock out all channels. There must be at least one
active channel in each bank.
To lock out a frequency while searching, press L/OUT when the scanner
displays the desired frequency. To lock out a frequency manually,
manually select the frequency and press L/OUT until LOCK-OUT appears on
the display.
To lock out a frequency during a limit or direct search, press L/OUT when
the scanner stops on the frequency. The scanner locks out the frequency,
then continues searching.
NOTES: If you press DIRECT, LIMIT, or TUNE, then press L/OUT, the scanner
will not lock out a channel or frequency. Choose another function,
then try pressing L/OUT again.
The scanner does not store locked-out frequencies during a limit or
direct search.
You can lock out as many as 200 frequencies. If you try to lock
out more than 200 frequencies, L-FULL appears on the display.
Follow these steps to remove the lockout from a frequency.
1. Press TUNE.
2. Repeatedly press L/O RVW until the frequency you want to remove the
lockout from is displayed.
3. Press L/OUT. LOCK-OUT disappears from the display.
Reviewing Locked-Out Channels and Frequencies
You can review the channels or frequencies you locked out.
To review the channels you locked out, press MANUAL, then repeatedly press
L/O RVW. As you press L/O RVW, the scanner displays all locked-out
channels.
To review the frequencies you locked out, press TUNE, then press L/O RVW.
The scanner sounds two short beeps, then displays L-r. As you rotate the
TUNING knob, the scanner displays all locked-out frequencies. To return
to the tune mode, press L/O RVW again.
NOTE: As you review locked-out frequencies, the scanner beeps when the
display changes from the highest locked-out frequency to the lowest
locked-out frequency.
Deleting All Locked-Out Frequencies
You can delete all locked-out frequencies at one time.
1. Press TUNE. TUNE appears on the display.
2. Press L/O RVW.
3. Press and hold down CLEAR, then press LOCK-OUT.
PRIORITY
With the priority feature, you can scan through programmed channels and
still not miss an important or interesting call on a specific channel.
You can program one stored channel as a priority channel.
NOTE: Before you first program your scanner, it automatically designates
Channel 1 in Bank 1 as the priority channel.
Follow these steps to program a channel as the priority channel.
1. Press PROGRAM.
2. Use the number keys to enter the channel number you want to program as
the priority channel, then press PRIORITY. P appears on the display
to the left of the channel number.
To turn on the priority feature, press PRIORITY during scanning. The
scanner checks the priority channel every 2 seconds. It stays on the
channel if there is activity, and PRIORITY appears.
To turn off the priority feature, press PRIORITY. PRIORITY 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 a locked-out channel.
Follow these steps to manually select a channel.
1. Press MANUAL.
2. Use the number keys to enter the channel number you want to hear, then
press MANUAL.
NOTES: If your scanner is scanning and stops at the channel you want,
press MANUAL once.
If you repeatedly press MANUAL, the scanner steps through the
channels. To change the step direction, press either /\ or \/
before you press MANUAL.
LISTENING TO THE WEATHER BAND
The FCC (Federal Communications Commission) has allocated 11 channels for
use by the National Oceanic and Atmospheric Administration (NOAA). NOAA
broadcasts your local forecast and regional weather information on one or
more of these channels. We have preprogrammed your scanner with ten of
the U.S. frequencies available to NOAA.
To scan the preprogrammed weather channels, repeatedly press WEATHER, or
press WEATHER then turn TUNING.
NOTE: For a list of all 11 national weather frequencies, see "National
Weather Frequencies" on Faxback Doc. # 31535.
BAND MODE AND FREQUENCY STEP
The scanner scans in the following band modes:
AM (amplitude modulation) - used in aircraft bands and Citizen's Band.
NFM (narrow band frequency modulation) - used in action bands such as
police, fire, ambulance, Amateur Radio, etc.
WFM (wide band frequency modulation) - used in commercial FM broadcasts
and television sound.
This table shows the preset band modes and frequency steps you scanner
uses for each frequency range.
Frequency Range (MHz) Band Mode Frequency Step (kHz)
25.000 - 29.995 AM 5
30.000 - 87.495 NFM 5
87.500 - 107.950 WFM 50
108.000 - 136.9875 AM 12.5
137.000 - 224.995 NFM 5
225.000 - 400.000 AM 12.5
400.0125 - 520.000 NFM 12.5
760.000 - 1300.000 NFM 12.5
If you scan some of the 225-400 MHz and TV audio bands, you might have to
manually change the band mode or frequency step.
Changing/Resetting the Band Mode
To change the displayed band mode while a frequency appears, press MODE
until the desired band mode appears. The band mode flashes anytime it is
different from the preset band mode. To reset the displayed band mode to
its preset, press RESET.
NOTES: You cannot change the band mode unless it appears on the display.
Keep in mind that improperly changing the band mode can cause poor
reception. For example, the sound is distorted when you listen to
an FM broadcast or TV audio in the NFM mode or to a police
broadcast in the WFM mode.
Changing/Resetting the Frequency Step
The scanner searches at a preset frequency step (5, 12.5 or 50 kHz) for
each frequency range. However, if you search some of the 225-400 MHz and
TV audio bands, you might have to manually change the frequency step.
When the scanner displays a frequency range, it also displays the frequency
step. You can change the displayed frequency step while searching for
frequencies or automatically storing frequencies.
To change the displayed frequency step, press STEP until the desired step
appears. (The frequency step flashes anytime it is different from the
preset frequency step l.)
To change a displayed frequency step back to its preset value, press
RESET.
NOTES: You cannot change the frequency step unless it appears on the
display.
Keep in mind that improperly changing the frequency step can cause
you to miss stations while scanning. For example, if you use a 50
kHz frequency step to search for broadcasts, and the band mode is
set to NFM, you might miss frequencies between the 50 kHz steps.
