Scanner Setup
Vehicle (Direct)
1. Disconnect the cable from your vehicle battery’s negative (–)
terminal.
2. Ground the black wire of the supplied DC power cord to your
vehicle’s chassis. The grounding screw must make complete
contact with your vehicle’s metal frame.
3. Connect the red wire of the supplied DC power cord to a
voltage source that turns on and off with the ignition switch, such
as a spare accessory terminal in your vehicle’s fuse box.
4. Insert the power cord’s barrel plug into the scanner’s DC 13.8V jack.
5. Reconnect the cable to your vehicle battery’s negative (–) terminal.
Headphones and Speakers
You can plug headphones or an external speaker (neither included)
into your scanner.
To use headphones, connect the plug into the headphone jack
on the front panel. Headphones automatically mute the scanner’s
speaker.
To use an external speaker, connect the plug into the EXT SP jack on
the rear panel.
Listening Safety
To protect your hearing, follow these earphone or headphones
guidelines:
• 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 listening. Turn on the
scanner, 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.
• 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-197
or PRO-106 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.
