Radio Shack REALISTIC PRO-2042 - Special Scanner Features

SPECIAL FEATURES
DELAY
Many agencies use a two-way radio
system that might have a pause of se¬
veral seconds between a query and a
reply. Your scanner’s delay feature lets
it wait for 2 seconds after each trans¬
mission on a channel or frequency
while scanning or searching.
To program a 2-second delay for a
channel while scanning, manually se¬
lect the channel and press DELAY until
DELAY appears. When your scanner
stops on the channel, it waits for 2 se¬
conds 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 trans¬
mission, 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 scan¬
ner’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 si¬
gnals.
USING THE SOUND
SQUELCH SWITCH
You can have the scanner skip fre¬
quencies 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.
