Cautions: - If the new device cannot be remotely 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 beeps once when powered on. - If the receiver cannot be controlled by the emitter, check whether the battery contacts are normal and whether the battery power is sufficient. Replace the battery promptly when it is low. Insensitive remote control may result from environmental interference or low battery. - Remove the battery when the device is not in use for an extended period. Wire connections must strictly follow the parameters indicated on the labels. Improper wiring may significantly reduce the device’s 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 the remote. The receiver emits a beep sound when the remote button is pressed, which may be noticeable in quiet environments. Ensure adequate space inside the fan canopy or mount the receiver beside it as needed.
