4. Operating Instructions
Your LOZ Sweet Heart Fluid Music Box is designed for interactive display and enjoyment.

- Light Feature: The integrated light strip illuminates the model. The power source for the light strip is typically a small battery pack (batteries not included, type usually specified in the assembly manual). Ensure batteries are correctly installed. There may be a small switch to turn the lights on and off.
