USING VEHICLE BATTERY 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 C Adaptaplug (neither supplied). Both are
available at your local RadioShack store.
Cautions:
You must use a power source that supplies regu-
lated 9V DC and delivers at least 300 mA. Its cen-
ter tip must be set to positive and its plug must fit
the scanner's
PWR DC 9V
jack. Using an adapter that does
not meet these specifications could damage the scanner
or the adapter.
• Always connect the DC adapter to the scanner before you
connect it to the power source. When you finish, discon-
nect the adapter from the power source before you discon-
nect it from the scanner.
To power the scanner using a DC adapter, attach the Adapta-
plug to the DC adapter so the tip reads positive (+), set the
adapter’s voltage switch to 9V, then insert the Adaptaplug into
the scanner’s
PWR DC 9V
jack. Plug the other end of the DC
adapter into your vehicle’s cigarette-lighter socket.
Note: If you use a cigarette-lighter power cable and your vehi-
cle’s engine is running, you might hear electrical noise from the
engine while scanning. This is normal.
CHARGING RECHARGEABLE
BATTERIES
Your scanner has a built-in charging circuit that lets you charge
rechargeable batteries while they are in the scanner. To
charge rechargeable batteries, you need to use an AC adapter
which supplies 9V (RadioShack Cat. No. 273-1767) or a DC
adapter which supplies 10V (Cat. No. 273-1830). Connect a
size C Adaptaplug to the adapter’s cable with the tip set to pos-
itive then insert the Adaptaplug into the scanner’s
PWR DC 9V
jack.
