Battery Pushbutton
The battery pushbutton is used to turn the battery ON and OFF.
The pushbutton is an alternate operation (two-position) type. When the pushbutton is in the extended
position, the battery is OFF. When the pushbutton is in the retracted position, the battery is ON.
When the battery is ON, the battery LED indicators are active. In this state, the battery consumes elec-
tricity and can be depleted. The battery should not remain ON during long periods of storage or unuse.
When the battery is OFF, the battery LED indicators are inactive. Turn the battery OFF for long periods
of storage or unuse.
Precautions for Correct Use
When the battery is turned OFF, all internal calibration data about the charge level is lost. Turn-
ing the battery ON will activate the battery LED indicators, but the charge level may not be rep-
resented accurately. Charge the battery completely to recalibrate and display the charge level
accurately.
