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.
Replacing the battery in the control panel
A battery is used in all control panels, except the basic control panel that does not
support the clock function, to keep the clock operating in memory during power
interruptions.
The expected life for the battery is greater than ten years.
Note: The battery is NOT required for any control panel or drive functions, except the
clock.
1. Remove the control panel from the drive. See section Control panel on page 37.
2. To remove the battery, use a coin to rotate the battery cover on the back of the
control panel.
3. Replace the battery with type CR2032. Dispose the old battery according to local
disposal rules or applicable laws.
