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
Radio Shack Cat. No. 20-188. Plug the adapter’s barrel plug into the
scanner’s
DC 9V
POWER
jack. Then plug the adapter’s power module
into a standard AC outlet.
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 9 volts and delivers at
least 300 milliamps. Its center tip must be set to negative, and its
plug must correctly fit the scanner’s
DC 9V POWER
jack. The rec-
ommended adapter meets these specifications. Using an adapter
that does not meet these specifications could seriously damage
the scanner or the adapter.
•
When you finish using the AC adapter, disconnect it from the AC
outlet first. Then disconnect it from the scanner.
Note: If you installed rechargeable nickel-cadmium batteries in the
scanner, remove the cap from the
CHARGE
jack and connect the AC
adapter to it. This powers the scanner and recharges the batteries at the
same time. See “Charging Nickel-Cadmium Batteries.”
