Charging the SG20B Scanner
When the scanner is correctly docked in the charger it beeps 
twice.

check the following:
• Scanner is correctly inserted in the charger base.
• Power is supplied to the charge base via the correct DC power 
supply or USB cable (= 500 mA).
• Battery contacts are clean. To clean the contacts, rub them 
with a pencil eraser and remove any eraser debris.
