Setup
1. Unpacking and Inspection

3. Setting the Time
After installing the batteries, the clock hands will begin to move. To set the correct time:
- Locate the time setting knob on the back of the clock (often a small wheel or knob).
- Rotate the knob to move the minute and hour hands clockwise until the correct time is displayed.
- Ensure the clock is set to the correct AM/PM if it affects the light sensor or melody playback schedule.
4. Mounting the Clock
The clock is designed for wall mounting. Choose a suitable location on a sturdy wall, away from direct sunlight or heat sources that could affect its operation.
- Use a screw or hook appropriate for the clock's weight (approximately 5.7 pounds) and wall material.
- Hang the clock securely using the mounting slot on the back.

2. Melody Selection
The clock offers three sets of melodies. You can select your preferred set using the control panel on the back of the clock.
- Classic Selection: The Four Seasons "Spring", Kanon, Eine Kleine Nachtmusik, Symphony No. 6 "Pastoral", Morning from Peer Gynt, La Traviata "Drinking Song", Amazing Grace, The Planets "Jupiter", Waltz of the Flowers, Salut d'Amour, Pictures At An Exhibition "Promenade", Dance Of The Reed Pipes.
- Christmas Selection: Deck The Halls, O Tannenbaum, We Wish You A Merry Christmas, Joy To The World, Silent Night, Jingle Bells.
- Note: A third set may be available depending on the specific model variant. Refer to the label on the back of your clock for details.
3. Volume Control
Adjust the melody volume using the volume control knob located on the back of the clock (refer to Figure 2). Turn the knob to increase or decrease the sound level.
4. Light Sensor
The built-in light sensor automatically disengages all melodies and motion when the room becomes dark. This feature conserves battery life and prevents melodies from playing during nighttime hours. The melodies and motion will resume automatically when sufficient light is detected.
5. Demonstration Button
Press the demonstration button (located on the back, refer to Figure 2) to play a melody and activate the motion sequence at any time, regardless of the hour.
Maintenance
1. Battery Replacement
When the melodies become faint, the motion slows, or the clock stops keeping accurate time, it is an indication that the batteries need to be replaced. Replace all four C batteries simultaneously with new, high-quality alkaline batteries. Do not mix old and new batteries or different types of batteries.
2. Cleaning
To clean the clock, gently wipe the surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the finish and internal components. For the glass, a mild glass cleaner applied to a cloth (not directly to the clock) can be used sparingly.
