UNDERSTANDING
YOUR
SCANNEH
The
antenna
jack
on
your
scanner
makes it
easy to use
your
scanner
with
a
variety
of antennas.
You
can
remove
the supplied antenna,
if
you
want,
and attach a different
one, such
as an external
mobile
antenna,
tele-
scopic antenna, or outdoor base an-
tenna.
Radio Shack stores sell the
antenna connector adapters that
let
you
use these antennas.
Use coaxial cable to connect an out-
door antenna.
Always
use
50-ohm co-
axial
cable. For lengths over 50
feet,
use
RG8 low-loss
dielectric coaxial
cable.
CONNECTING
AN
EARPHONE
For
private
listening,
plug
an ear-
phone
into the
EAR
jack
on top of
your
scanner.
This automatically
dis-
connects
the speaker.
We recom-
mend Radio Shack's earphone
Cat.
No.
33-175.
ln a
noisy environment,
mono
headphones
(Cat.
No. 20-210)
make listening easier.
Always set
volume
to
its minimum
po-
sition before
you
plug
in
earphones or
headphones. Then,
adjust the
volume
to a confortable
listening level.
Warning: Do not listen
at extremely
high volume levels,
especially
when
using an
earphone. Extended
high-
volume listening
can
lead
to
perma-
nent hearing loss.
CONNECTING
AN
EXTENSION SPEAKER
ln
a
noisy
area, an extension
speaker
such as
Radio
Shack Cat.
No. 21-
549,
positioned
in
the
right
place,
might
provide
more comfortable
lis-
tening.
Plug
the speaker cable's
1/8-
inch mini-plug into
the scanner's
EAR
jack.
A LOOK

The display
has
several
indicators
that show the scanner's

ating

play
