Battery and power supply/charger
Understand and follow the precautions below before using your battery or power
supply/charger. See power supply/charger manual for more information.
• 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. The power supply/charger is for indoor use only.
• 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.
• Clean the power supply/charger by clearing the terminal of dirt and debris. However,
no cleaning is required.
• If the power supply/charger is used in a manner not specified by Emerson Process
Management, the protection provided by the equipment may be impaired.
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 the 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.
