Cleaning the control panel

Use a soft damp cloth to clean the control panel. Avoid harsh cleaners which could

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.
