Understanding LED
signals
The Field PC signals events and processes using a
charge LED and a notification LED.
Charge LED. This red light appears to the left of the
Start menu button. A flashing light signals that the
battery is currently charging; a solid light signals that
the wall charger is connected but that the battery is
fully charged.
Note : When the device is suspended or
powered off, the charge LED does not appear.
Notification LED. Appearing on the right side of the
Enter button, the green notification LED appears briefly
when you power on the unit after the device is reset or
restored to factory defaults.
