Remote Fuel Gauge
To display the charge level of the NiMH cells when operating on DC power, a Remote Fuel
Gauge is connected to the power supply. The embedded Remote Fuel Gauge is located just
below the monitor in the stalk and gives the user the current battery status at eye level height.
Remote Fuel Gauge
If the battery is fully charged, all five (5) amber LEDs are illuminated. The LEDs always display
the battery charge level whether the computer is operating or not. As the battery looses charge,
the LEDs gradually turn off, one at a time. Once the top four LEDs are off and only the amber
LED marked “LOW” is illuminated and flashing, it is recommended to plug the AC cord into an
AC outlet as soon as possible to charge the battery.
Notice:
Once the amber LED marked “LOW” starts to flash, plug the power supply into
an AC outlet to avoid loss of system power, which may cause loss of data.
Notice:
Once the NiMH Power Supply has been plugged into an AC outlet, the Remote
Fuel Gauge two green LEDs marked “AC” and “CH” turn on.
