Quick Start
step 5: monitoring and scanning
monitoring
To monitor a channel, press SCAN/MANUAL while the scanner is
pausing on the channel, or stop the scanning by pressing SCAN/
MANUAL, enter the channel number, and press SCAN/MANUAL.
scanning
To scan, press SCAN/MANUAL. When the scanner nds a
transmission, it monitors the transmission until it ends.
If you have not stored frequencies into any channels,
the scanner cannot scan.
If the scanner picks up weak transmissions, turn
SQUELCH clockwise to decrease the scanner’s
sensitivity to these signals. To listen to a weak or
distant station, turn SQUELCH counterclockwise.
Press SCAN/MANUAL to stop scanning, or press HOLD/RESUME
to pause the scan without losing your position.
earphones / headphones
For private listening, you can plug earphones or headphones into
your scanner’s headphone jack. Do not use headphones with your
scanner when operating a motor vehicle in or near traf c. Doing so
can create a traf c hazard and could be illegal in some areas. Some
headphones let you hear some outside sounds when listening at
normal volume levels, but they still can present a traf c hazard.
To protect your hearing, follow these guidelines for headphones.
Do not listen at extremely high volume levels. Extended high-
volume listening can lead to permanent hearing loss.
Set the volume to the lowest setting before you begin listening,
then adjust the volume to a comfortable level.
After you set the volume, do not increase it. Over time, your
ears adapt to the volume level, so a volume level that does not
cause discomfort might still damage your hearing.
