Battery and Power Supply/Charger

Understand and follow the precautions below before using your battery or power 
supply/charger.
• Protect the battery and power supply/charger from moisture, and respect operating 

and storage temperature limits. See the 

475 Field Communicator User’s Manual

 for 

temperature limits.

• Do not cover the battery or power supply/charger, subject it to prolonged periods of 

direct sunlight, or place it upon or next to heat-sensitive materials. 

• Charge the battery with only the power supply/charger. The power supply/charger 

should not be used with other products. Failure to comply may permanently damage 
your 475 Field Communicator and void the IS approval and the warranty.

• Do not open or modify the battery or power supply/charger. There are no 

user-serviceable components or safety elements inside. Opening or modifying them 
will void the warranty and could cause personal harm.

• Follow all applicable regulations when transporting a Li-Ion battery.

Charging the Battery

Prior to first portable use, fully charge the Li-Ion battery. The power supply/charger has 
a green connector to match the connector on the battery. The battery can be charged 
separately or while attached to the 475 Field Communicator. A full charge takes 
approximately two to three hours, and the 475 is fully operable when charging. An 
overcharge condition will not occur if power supply/charger remains connected after 
charging completes. 

To maintain performance, charge the battery frequently, preferably after each use. Limit 
full discharges, if possible. Additional information about maintaining the battery is in the 

475 Field Communicator User’s Manual
