Scanner Setup
• Do not wear an earphone or headphones with your scanner
when operating a motor vehicle or riding a bicycle in or near
traffic. Doing so can create a traffic hazard and could be illegal in
some areas.
• Even though some earphones/headphones let you hear some
outside sounds when listening at normal volume, they can still be
a traffic hazard.
Transferring Data To or From another Scanner or PC
You can transfer the programmed data to and from another PRO-
652
or PRO-
651
scanner using a connecting cable which has 1/8-inch
(3.5mm) stereo (TRS) phone plugs on both ends (not supplied). See
“Cloning” on page 71.
You can also upload or download programmed data to or from a PC
using a USB cable available through your local
RadioShack store or
at RadioShack.com. To find the application software, we recommend
using an internet search engine to search for “scanner programming
software.”
Turning on the Scanner and Setting Squelch
1. Turn the VOLUME and SQUELCH knobs clockwise to about
their mid-point (12:00 o’clock) position.
Note:
Make sure the scanner’s antenna is connected before you turn it on.
2. Press TUNE .
3. Turn SQUELCH down (counterclockwise) until you hear noise.
4. Turn SQUELCH up (clockwise) a little past where the noise stops.
The higher the squelch is set, the stronger the signal required to
break the squelch.
5. If noise starts breaking the squelch, turn SQUELCH up to
decrease the scanner’s sensitivity. To hear weaker signals, turn
SQUELCH down to increase its sensitivity.
