Pendulum:
The pendulum is for decorative purposes and provides a gentle swinging motion. Ensure it is free to swing without obstruction.
Maintenance
Cleaning:
Wipe the clock surface with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the finish.

Replace batteries when the clock hands slow down or the cuckoo sound becomes faint or stops. Always replace all batteries at the same time with new ones of the same type.
Storage:
If storing the clock for an extended period, remove the batteries to prevent leakage and damage.
