Cautions: When the new device cannot be remote controlled, check whether the bar codes in the emitter and receiver match, whether the indicator light on the emitter is working, whether the receiver 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 has sufficient power. Replace the battery promptly when it is low. Insensitive remote control response may be due to environmental interference or low battery. Remove the battery if the device is not used for an extended period. Wire the device strictly according to the parameters labeled on the product. Incorrect wiring may shorten the device's lifespan or cause immediate malfunction. The antenna must not be connected to other wires. If there is a code switch on the fan, set the fan to the highest speed before remote operation. The receiver may beep when the remote is pressed, which could be noticeable in quiet environments. Ensure sufficient space in the fan canopy; otherwise, the receiver may need to be mounted nearby.
