3. The charging indicator LED should light yellow.
Note: If the red "FAULT" LED lights when the AC connection is made, check
all connections. If all connections are correctly seated, suspect a faulty
battery.
4. When the unit has reached full charge, the yellow CHARGING LED will turn off and
the green FULL LED will light. The unit is ready for service. The unit is equipped with
overcharge protection and can remain connected to AC indefinitely without adverse
consequences.
Note: If the unit is charging for over 24 hours without achieving a green FULL
LED, the internal battery may be compromised.
