Charging the Battery
Prior to first portable use, fully charge the battery. The battery can be charged
separately or while attached to the 475 Field Communicator. The 475 Field
Communicator is fully operable while the battery is recharging, and a full charge takes
2-3 hours. An overcharge condition will not occur if the power supply/charger remains
connected.
CAUTION
You can remove and install the battery in a hazardous area environment. You cannot
charge the battery in this environment because the power supply/charger is not
IS-approved.
To charge the battery:
1. Plug the power supply/charger into a power outlet.
2. Plug the green power supply/charger connector into the green connector on the
battery. The flat side of the power supply/charger connector should face the front of
the 475 or the inside of the battery, if the battery is not attached to the 475. The
battery is fully charged when the light on the power supply/charger is green.
