5.2 Cuckoo Feature
The Karlsson KA5789BK features a charming cuckoo sound. The cuckoo will emerge and chime on the hour. This clock is designed to be a "silent clock" in terms of its movement, meaning the ticking sound is minimal or absent, but the cuckoo chime will activate.
Some cuckoo clocks have light sensors to prevent chiming in the dark. If your clock has this feature, ensure it is in a well-lit area during the day for proper operation of the cuckoo mechanism.
6. Maintenance
- Cleaning: Wipe the clock with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the finish.
- Battery Replacement: Replace all batteries when the clock starts to lose time or the cuckoo feature becomes weak or stops.
- Storage: If storing the clock for an extended period, remove the batteries to prevent leakage.
