Control panel


Cleaning the control panel
Use a soft damp cloth to clean the control panel. Avoid harsh cleaners which could
scratch the display window.

Changing the battery in the assistant control panel
A battery is only used in assistant control panels that have the clock function
available and enabled. The battery keeps the clock operating in memory during
power interruptions.
The expected life for the battery is greater than ten years. To remove the battery, use
a coin to rotate the battery holder on the back of the control panel. Replace the
battery with type CR2032.
Note: The battery is NOT required for any control panel or drive functions, except the
clock.
LEDs
There is a green and a red LED on the front of the drive. They are visible through the
panel cover but invisible if a control panel is attached to the drive. The assistant
control panel has one LED. The table below describes the LED indications.
