Checking the remaining charge
To view the remaining charge, press the Charge Indicator button on
the lower left side of the battery. See Figure 2-1 for the location of this
button. When you press and release the button, the lights above the
button slowly illuminate to display the charge remaining. Each light
represents 20 percent of the charge. The battery is fully charged when
all of the lights are illuminated.
You can also check the remaining charge from the Settings menu on
the Field Communicator Main Menu. See "Power" on page 25 for more
information.

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 Li-Ion battery in a hazardous area
environment. You cannot charge the battery in this environment
because the power supply/charger is not IS-approved.
