Warning:
 Never use the
CHARGE jack when you have
installed non-rechargeable

hot and could explode.
Remove the plastic plug
from the 
CHARGE jack before
you use it, then replace the
plug when you finish.

USING VEHICLE 
BATTERY POWER
You can power the scanner
from a vehicle’s 12V power
source (such as cigarette-
lighter socket) using a 9V,
300-mA DC adapter and a
size H Adaptaplug adapter
(neither supplied). Both are
available at your local Ra-

CHARGE jack and
connect an AC adapter to
the jack.
Warning:

adapter to the scanner’s

Connecting an 
Outdoor Antenna
Instead of the supplied an-
tenna, you can connect an
outdoor base-station or mo-
bile antenna (not supplied)
to your scanner using a BNC
connector. Your local Ra-

route the antenna’s cable to
the scanner and connect the
cable to the scanner’s anten-
na jack.
Cautions:
• Do not run the cable
over sharp edges or
moving parts that might
damage it.
• Do not run the cable
next to power cables or
other antenna cables.
Warning: 
Use extreme
caution when you install or
remove an outdoor anten-
na. If the antenna starts to
fall, let it go! It could con-
tact overhead power lines.
If the antenna touches a
power line, contact with the

volume listening can
lead to permanent hear-
ing loss.
• Once you set the vol-
ume, do not increase it.
Over time, your ears
adapt to the volume
level, so a volume level
that does not cause dis-
comfort might still dam-
age your hearing. 
Traffic Safety
• Do not use an earphone/
headphones with your
scanner when operating
a motor vehicle or riding
a bicycle in or near traf-
fic. Doing so can create
a traffic hazard and
could be illegal in some
areas.

UNDERSTANDING YOUR SCANNER
Once you understand a few simple terms we use in this manual
and familiarize yourself with your scanner’s features, you can
put the scanner to work for you. You simply determine the type
of communications you want to receive, then set the scanner to
scan them.
A frequency
 is the tuning location of a station (expressed in kHz
or MHz). To find active frequencies, you can use the search
function. 
When you find a frequency, you can store it into a programma-
ble memory...
