HH492 User Guide 9
Charge Information
The battery is designed to charge while the scanner is positioned in the cordless 
base unit. Refer to Scanner LED Sequences and Beeper, page 10, for an 
interpretation of the Charge Status indicators. 
Place the scanner in the base that is connected to an appropriate power supply. 
Use only a Listed Limited Power Source (LPS) or Class 2 type power supply with 
output rated 5 to 5.2Vdc, 1A.
Note: If you are powering the base through the interface cable (for example, a USB cable) 
and not using an external power supply plugged into the aux port, the current 
available for charging is reduced and charge times are increased.

Power is supplied to the  scanner by a rechargeable battery that is integrated in the
