Radio Shack REALISTIC PRO-2042 - Scanner Operation and Search Modes; Basic Operation and Tuning

OPERATION
TURNING ON THE
SCANNER/SETTING
VOLUME AND SQUELCH
1. Turn SQUELCH fully counterclock¬
wise.
2. Turn VOLUME clockwise until you
hear a hissing sound. The scanner
turns on and SCAN, a channel
number, and a frequency appear
on the display. Then the scanner
scans any frequencies already
stored in any active banks.
Note: If you have not stored any
frequencies or activated any banks
yet, the scanner does not scan.
3. Turn SQUELCH clockwise, then
leave it set to a point just after the
hissing sound stops.
Note: If the scanner picks up unwan¬
ted, partial, or very weak transmis¬
sions, turn SQUELCH clockwise to de¬
crease the scanner’s sensitivity to
these signals. If you want to listen to a
weak or distant station, turn SQUELCH
counterclockwise.
USING THE ROTARY
TUNER
When you set the scanner to scan or
search, it uses hyperscan to automati¬
cally scan up to 50 channels or search
up to 50 steps per second.
The scanner’s rotary tuner lets you
quickly select channels and frequen¬
cies manually. As you turn TUNING one
click, the channel or frequency chan¬
ges one step at a time.
Note: If you quickly turn TUNING, the
rate at which the scanner tunes
through the channels or frequencies
becomes faster.
Tuning Channel Numbers
To tune channel numbers, press MA¬
NUAL, then turn TUNING clockwise (to
tune to higher channel numbers) or
counterclockwise (to tune to lower
channel numbers).
Notes:
• If you have not stored any fre¬
quencies into channels yet, the
scanner displays the empty chan¬
nels.
• You cannot use the rotary tuner to
tune to a channel while the scan¬
ner is scanning the priority chan¬
nel.
Tuning Frequencies
Notes:
• You can use the rotary tuner to
tune frequencies during a search
(see “Searching For and Storing
Active Frequencies” on Page 19).
