1. Setup
1.1 Unboxing and Initial Inspection
Carefully remove all components from the packaging. Inspect the clock unit, pendulum, and decorative weights/chains for any signs of damage. Ensure all parts are present before proceeding with installation.

1.2 Battery Installation
The Rylai Cuckoo Clock requires two LR20/D batteries (not included). Locate the battery compartment on the back of the clock. Insert the batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
1.3 Attaching Pendulum and Weights
Gently attach the pendulum to the hook located at the bottom center of the clock mechanism. The decorative weights are attached to the chains. Ensure they hang freely and are not tangled.

1.4 Mounting the Clock
Select a stable wall location for mounting. The clock is designed for wall mounting. Use appropriate hardware (not included) to securely hang the clock. Ensure it is level to allow the pendulum to swing correctly.

2. Operating Instructions
2.1 Setting the Time
To set the time, gently turn the minute hand (the longer hand) clockwise until the correct time is displayed. The clock will automatically adjust its chime sequence to the set time.
2.2 Cuckoo Chime Functionality
The cuckoo bird emerges and sings 'co co' every hour, corresponding to the number of hours. For example, at 3 o'clock, it will chime three times.

2.3 Volume Control
The clock features an adjustable volume control with three settings: High, Low, or Shut off. This switch is typically located on the side or back of the clock. Adjust to your preferred sound level.
2.4 Automatic Night Shut-Off Sensor
The cuckoo clock is equipped with an automatic night shut-off sensor. This sensor detects ambient light and will automatically silence the cuckoo chime during dark hours, ensuring undisturbed sleep. The chime will resume automatically when the room becomes bright again.

3. Maintenance
3.1 Cleaning
To maintain the clock's appearance, regularly dust the wooden surfaces with a soft, dry cloth. Avoid using abrasive cleaners or harsh chemicals, as these may damage the finish. For intricate carved areas, a soft brush can be used.
3.2 Battery Replacement
Replace the LR20/D batteries when the clock's timekeeping becomes inaccurate or the cuckoo chime weakens or stops. Always replace both batteries simultaneously to ensure optimal performance.
3.3 General Care
Position the clock away from direct sunlight, extreme temperatures, and high humidity to prevent warping or damage to the wood. Handle the pendulum and weights gently to avoid bending or breaking the chains.
4. Troubleshooting
4.1 Clock Not Keeping Accurate Time
- Check Batteries: Ensure batteries are fresh and correctly installed with proper polarity.
- Pendulum Swing: Verify that the pendulum is swinging freely and is not obstructed. The clock must be level for proper pendulum operation.
4.2 Cuckoo Chime Not Working or Bird Not Appearing
- Volume Setting: Confirm the volume switch is not set to 'Off'.
- Night Sensor: Ensure the room is adequately lit during the day, as the night sensor will silence the chime in darkness.
- Bird Mechanism: Gently check if the cuckoo bird is stuck or obstructed within its opening.
4.3 Sound Quality Issues
- Volume Adjustment: Adjust the volume setting to 'High' or 'Low' as desired.
- Battery Level: Low batteries can affect sound quality. Replace if necessary.
