Maintenance and Care
Proper care will ensure the longevity of your Cogo building set:

- Storage: Store the building set in a cool, dry place, away from direct sunlight and extreme temperatures. Keeping the pieces in their original box or a dedicated storage container can help prevent loss and damage.
- Luminous Brick: Keep the luminous brick dry. If battery replacement is ever needed (though typically not user-serviceable), refer to the specific instructions provided with the brick or contact customer support.
Troubleshooting
If you encounter any issues during assembly or play, please refer to the following common solutions:
- Missing Pieces: Double-check all packaging materials. If a piece is genuinely missing, please contact Cogo customer support with details of the missing part (as identified in the instruction booklet).
- Difficulty Assembling: Review the instruction booklet carefully, paying close attention to the diagrams for each step. Ensure you are using the correct pieces and that they are oriented correctly. Sometimes, a piece may require a firm press to connect properly.
- Luminous Brick Not Working:
- Ensure the brick is correctly installed according to the assembly instructions.
- Press the activation button/switch firmly.
- If the brick uses replaceable batteries (uncommon for small integrated bricks), check if they are correctly inserted or need replacement. (Consult the brick's specific instructions if available).
