5. Operating Instructions
5.1 Setting the Time
- Locate the time setting knob or wheel on the back of the clock's mechanism.
- Gently turn the knob clockwise to set the hour and minute hands to the correct time.
- Avoid turning the clock hands directly, as this may cause damage to the internal mechanism.
5.2 Cuckoo Chime Function
This clock features an hourly cuckoo chime, where the cuckoo bird emerges and sounds on the hour.
- The chime mechanism is designed to operate during specific hours, typically silencing automatically during nighttime (e.g., from 10 PM to 5 AM) to ensure quiet.
- For the chime to function correctly, ensure the clock is mounted level and the batteries are sufficiently charged.
