The POWER jack powers the scanner and disconnects the internal bat-
teries. You can use this jack to connect an external power source (AC
adapter or DC power cord) regardless of the type of batteries you install.
The CHARGE jack supplies power to operate the scanner and also
charges the internal batteries. Use the CHARGE jack only when you in-
stall rechargeable nickel-cadmium batteries.
Warning: Never use the CHARGE jack with non-rechargeable batteries.
If you try to recharge non-rechargeable batteries, they become very hot
and could explode.
USING STANDARD AC POWER
To power the scanner from AC power, you need an AC adapter such as
Cat. No. 273-1652 (not supplied).
Warning: Do not use an AC adapter’s polarized plug with an extension
cord, receptacle, or other outlet unless the blades can be fully inserted
to prevent blade exposure.
Cautions:
• You must use an AC adapter that supplies 12 volts and delivers at
least 200 milliamps. Its center tip must be set to positive, and its
plug must correctly fit the scanner’s
POWER and CHARGE jacks.
The recommended adapter meets these specifications. Using an
adapter that does not meet these specifications could damage the
scanner or the adapter.
• Be sure you connect the AC adapter to the scanner before you
connect it to a standard AC outlet. Then disconnect the adapter
from the AC outlet before you disconnect it from the scanner.
Note: The scanner receives a 12-volt input at the CHARGE or POWER
jack and reduces it to the 6 volts required by the scanner.
