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

Connect a size B Adaptaplug to
the adapter’s cable with the tip set
to positive then insert the
Adaptaplug into the scanner’s

occasionally let them
fully discharge. To do
this, simply use the
scanner until Low
Battery! flashes on
the display and the
scanner beeps. Then
fully charge the
batteries.
