- Power Cord Care: Ensure the power cord is not twisted, kinked, pinched, or walked upon. Do not touch with wet hands. If wet or dusty, dry or wipe clean to prevent electric shock.
- Battery Replacement: For the remote control, replace batteries (1.5 V AAA) matching the polarity markings.
- Ventilation: Maintain a distance of more than 10 cm between the product and the wall. Avoid installing in enclosed spaces (bookshelves, cupboards) or on carpets/cushions. Ensure air vents are not blocked by tablecloths or curtains to prevent overheating and fire.
- Safety Precautions:
- Do not expose the product to rain, moisture, direct sunlight, high humidity, heat sources, steam, oil, or water containers.
- Avoid placing heavy objects on power cables.
- Do not insert metal objects into power cable ends or the product itself.
- Do not drop the product or allow it to fall.
- Keep anti-moisture packing material and vinyl packing away from children.
