non-rechargeable batteries, or recharge the rechargeable
batteries. See “Charging Rechargeable Batteries”.
Warning: Always dispose of old batteries promptly and
properly. Do not bury or burn them.

rechargeable batteries.
Important: This scanner can use nickel-
cadmium rechargeable batteries. At the

Using Vehicle Power
You can power the scanner from a vehicle’s 12V power
source (such as a cigarette-lighter socket) using a 9V,
300 mA DC adapter and a size H Adaptaplug (neither
supplied). We recommend RadioShack Cat. No. 273-
1810 (available at your local RadioShack store).

connect a DC adapter, unplug the DC adapter from the
cigarette-lighter socket and clean the socket to remove
ashes and other debris.

Connecting an Optional Antenna
The antenna connector on your scanner makes it easy to
use the scanner with a variety of antennas, such as an
external mobile antenna or outdoor base station antenna.
Your local RadioShack store sells a variety of antennas.
Always use 50-ohm coaxial cable, such as RG-58 or RG-
8, to connect an outdoor antenna. For lengths over 50
feet, use RG-8 low-loss dielectric coaxial cable. If your
antenna’s cable does not have a BNC connector, you will
also need a BNC adapter (also...

Listening Safely
To protect your hearing, follow these guidelines when you
use an earphone or headphones:
• Do not listen at extremely high volume levels.
Extended high-volume listening can lead to perma-
nent hearing loss.
• Set the volume to the lowest setting before you begin
listening. After you begin listening, adjust the volume
to a comfortable level.
• Once you set the volume, do not increase it. Over
time, your ears adapt to the volume level, so a vol-
ume level that does not cause discomfort...

scanner for hands-free carrying when you are on the go.
Slide the belt clip over your belt or waistband.
CONNECTING THE CLONE CABLE
You can transfer the programmed data to and from an-
other PRO-92 using the supplied clone cable. Connect
the cable between each scanner’s PC/IF jacks. See

ABOUT YOUR SCANNER
Once you understand a few simple terms used in this
manual and familiarize yourself with your scanner’s fea-
tures, you can put the scanner to work for you. You sim-
ply determine the type of communications you want to
receive, then set the scanner to scan them.
A 
frequency is the receiving signal location (expressed in
kHz or MHz). To find active frequencies, you can use the
search function. 
You can also search the SEARCH banks, which are pre-
programmed frequencies in the...
