Cautions: When the new device cannot be remote controlled, please check whether the barcodes on the emitter and receiver match, whether the indicator light on the emitter is functioning, whether the receiver cable is properly connected, and whether the buzzer beeps once when powered on. When the receiver cannot be controlled by the emitter, please check whether the battery contacts are normal and whether sufficient power remains. Replace the battery promptly when depleted. Insensitive remote operation may result from environmental interference or low battery. Remove the battery when the device is not in use for extended periods. Wire the device strictly according to the parameters indicated on the labels; improper wiring may significantly reduce device lifespan or cause immediate malfunction. The antenna must not be connected to other wires. If the fan has a code switch, set the fan to the highest speed before using remote control. The receiver emits a beep upon remote button press, which may be audible to some users. Ensure adequate space inside the fan canopy or mount the receiver beside it as needed.
