To connect an optional antenna, always
use 50-ohm coaxial cable, such as RG-
58 or RG-8. For lengths over 50 feet,
use RG-8 low-loss dielectric coaxial ca-
ble. If the coaxial cable's connector
does not fit in the ANT
jack,
you might
also need a PL-259-to-BNC antenna
plug adapter, such as Cat.
No.
278-
120.
Your local Radio Shack store car-
ries a wide variety of coaxial antenna
cable and
connectors.
Follow the mounting instructions sup-
plied with the
antenna.
Then route the
antenna cable to the
scanner,
and
connect it to the ANT jack on the
back of the scanner.
Caution: Do not run the cable over
sharp edges or moving objects.
Warning: Use extreme caution
when you install or remove an
outdoor antenna. If the antenna
starts to fall, let it go! It could
contact overhead power lines. If
the antenna touches a power
line, contact with the antenna,
mast, cable, or guy wires can
cause electrocution and death.
Call the power company to re-
move the antenna. DO NOT at-
tempt to do so yourself.
CONNECTING POWER
You can power your scanner from
either of these
sources:
• Standard AC power
• Vehicle battery power (using an op-
tional DC adapter)
The memory backup circuit begins to
function a few minutes after you con-
nect the scanner to AC or DC
power.
If a power failure occurs or if the
power cord is disconnected, this
cir-
cuit protects information in the
scan-
ner's memory for about 1 hour.
Connecting AC Power
Plug the scanner's AC power cord
into a standard AC outlet.
Caution: To prevent electric shock,
the plug's blades are polarized and fit
only one
way.
If the plug does not fit
easily, turn it over and try
again.
Do
not force the plug into the AC outlet.
