Charging the Scanner
Use the included AC adapter to charge the Cordless Hand Scanner. The
scanner’s NiMH batteries must be charged for at least 4 hours before the
first use. The Battery Status LED will emit a solid red light while charging,
and turn off when the batteries are fully charged.
WARNING: Do not attempt to charge alkaline batteries
— this may cause alkaline batteries to leak and damage
the CHS.
The red Battery Status LED will not function properly if
standard AAA alkaline batteries are being used.
