4. Setup: Assembly Instructions
Follow these steps carefully to assemble your Rotating Starry Night Music Box. Refer to the included graphical instructions for detailed diagrams and part identification. It is recommended to work on a clean, flat surface.
- Preparation: Carefully remove all wooden pieces from their sheets. Use a small tool or your fingers to gently detach them. Identify each piece according to the numbering or shapes in the instruction manual. Keep similar pieces grouped to avoid confusion.
- Base Assembly: Begin by constructing the base of the music box. Interlock the designated wooden parts as shown in the diagrams. Ensure all connections are secure and flush.
- Gear Mechanism Installation: Install the internal gear mechanism. Pay close attention to the orientation and alignment of each gear to ensure smooth operation. Incorrect alignment can prevent the music box from functioning.
- Orrery Structure: Assemble the orbital rings and supports for the planetary spheres. These form the framework for the rotating solar system model. Ensure the rings are free to move as intended.
- Music Box Mechanism Integration: Carefully integrate the music box mechanism into the assembled structure. Connect any necessary linkages to the gear system that drives the orrery's rotation.
- Final Assembly: Complete the remaining structural elements and decorative pieces. Double-check all connections for stability and proper alignment. Ensure all moving parts operate without obstruction.



5. Operating Instructions
To enjoy your ROBOTIME Rotating Starry Night Music Box:
- Winding the Music Box: Locate the T-key on the side or bottom of the music box. Gently turn the T-key clockwise until you feel slight resistance. Do not overwind, as this can damage the internal mechanism.

7. Troubleshooting
If you encounter issues with your music box, consider the following common solutions:
Music Box Not Playing or Rotating:
- Check Winding: Ensure the T-key has been fully wound (without over-winding). A partially wound mechanism may not have enough power to operate.
- Obstructions: Inspect the gear mechanism and rotating parts for any foreign objects, loose pieces, or misaligned components that might be blocking movement.
- Assembly Errors: Review the assembly instructions to confirm all parts are correctly installed and connected. Loose or incorrectly placed gears can prevent the music box from functioning.
Pieces Not Fitting:
- Identify Correct Piece: Double-check the part numbers and diagrams in the instruction manual to ensure you are using the correct piece for the slot.
- Gentle Pressure: Apply gentle, even pressure. Do not force pieces, as this can cause damage to the wood or the piece itself.
- Sanding: If a piece is slightly too tight, very gently sand the edges with fine-grit sandpaper (not included) to allow for a smoother fit.
Damaged or Missing Parts:
- If you discover damaged or missing parts upon opening the package or during assembly, please refer to the "Warranty and Support" section for contact information regarding replacement parts.
