Power is supplied by the integrated battery when the control panel is not connected to an external power source. The battery must be charged to insure uninterrupted use of the control panel as a mobile test unit. The battery is charged automatically as soon as the control panel is placed in the docking station or connected to the bench power supply. While the battery is being charged the "Battery" LED illuminates in yellow.

To achieve the longest possible service life for the integrated battery, it must be fully charged, then discharged for normal use. Once a month the battery should be "formed" which entails fully discharging the battery, then fully recharging it.

To "form" the battery:

Disconnect the bench power unit from the control panel or undock from the docking station or disconnect the docking station from a power source.
Fully discharge the battery, by leaving the control panel "ON" until all the LEDs are out.
Dock the control panel or supply power to the docking station or connect the bench power unit.

Charging is complete when the "Battery" LED goes out.

NOTE: Always replace a defective battery with a new battery. Never operate the control panel with out a battery (it acts as a buffer). Sudden interruption of power my cause the control panel to loose the installed operating system.
