Important Notes

• The LED panel achieves IP65 waterproof protection thanks to epoxy resin coating over the lamp beads, but the internal controller housing is not sealed against moisture. Avoid submerging the entire unit or exposing the controller to rain, sprinklers, or direct water spray.
• Stable Bluetooth connectivity between the device and smartphone is essential for full app functionality. Ensure your phone is within range (typically under 10 meters) and has sufficient battery to maintain connection during extended use.
• Installation via included double-sided tape works best on clean, dry, flat or slightly curved surfaces such as glass, metal, plastic, or painted walls. For optimal adhesion, ensure the surface is free of grease, dust, or oils before applying.
• Power requires a USB 5V source—either a wall adapter, power bank, or car USB charger. A Type-C charging cable is provided, but adapters may need to be purchased separately depending on your setup.
• While durable, avoid dropping the unit or applying excessive pressure to the flexible circuit board to prevent internal damage. Handle with care during transport or repositioning.
