Using Your Vehicle's Battery Power; Connecting An Extension Speaker - Radio Shack PRO-2050 Owner's Manual

Cautions:
• The supplied AC adapter supplies
12 volts DC power and delivers
500 milliamps. Its center tip is set
to positive, and its plug properly
fits the scanner's
Using an adapter that does not
meet these specifications could
damage the
adapter.
• Be sure to connect the AC
adapter to the scanner before you
connect it to an AC outlet, and dis-
connect the AC adapter from the
AC outlet before you disconnect it
from the scanner.
Warning: Do not use the AC adapt-
er's polarized plug with an extension
cord receptacle unless the blades can
be fully inserted to prevent blade ex-
posure.
Using Your Vehicle's Battery
Power
If your AC power fails (during an
emergency, for example), you can
power your scanner from your vehi-
cle's cigarette lighter socket with an
optional DC cigarette lighter power ca-
ble, such as Cat. No. 270-1533 (not
supplied).
To connect an optional DC cigarette
lighter power cable, insert its barrel
plug into the
DC 12V
of the scanner, then plug the power
cable into your vehicle's cigarette
lighter socket.

scanner or the
jack on the back
Cautions:
• If you use a DC cigarette lighter
power cable with the scanner, it
must supply 12 volts and at least
500 milliamps of DC automotive
power. Its center tip must be set to
positive, and its plug must cor-
rectly fit the
back of the scanner. The recom-
mended power cable meets these
specifications. Using a power
cable that does not meet these
specifications could damage the
scanner or the power cable.
• If you use a cigarette lighter power
cable and your vehicle's engine is
running, you might hear electrical
noise from the engine while scan-
ning. This is normal.
Note: Mobile use of this scanner is
unlawful or requires a permit in some
areas. Check the laws in your area.
CONNECTING AN
EXTENSION SPEAKER
In a noisy area, an amplified extension
speaker (such as Cat. No. 21-541),
positioned in the right place, might
provide more comfortable listening.
