Charging Well

Use only a Symbol approved power supply output rated 12 VDC and minimum 3.3 A. Use of an alternative 
power supply will void the product warranty and may cause product damage. See 

for the power supply regulatory compliance statement.

When a mobile computer with Microsoft Mobile 5.0 is placed in the cradle and an ActiveSync connection is 
made, the WLAN and WWAN radios (if applicable) are disabled. This is a Microsoft security feature to prevent 
connection to two networks at the same time.
