Cautions: - If the new device cannot be remote controlled, check whether the barcodes on the emitter and receiver match, whether the indicator light on the emitter is functioning, whether the receiver’s cable is properly connected, and whether the buzzer emits a single beep when powered on. - If the receiver cannot be controlled by the emitter, 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 if the device will not be used for an extended period. Wire the device strictly according to the specifications indicated on the labels. Failure to do so may significantly reduce device lifespan or cause immediate malfunction. The antenna must not be connected to any 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 when a remote button is pressed, which may be audible in quiet environments. Ensure adequate space inside the fan canopy or mount the receiver beside it as needed.
