Cautions: When the device cannot be remote controlled, check whether the bar codes in the emitter and receiver are consistent, whether the indicator light on the emitter is working, whether the cable of the receiver is connected properly, and whether the buzzer beeps once when power is on. When the receiver cannot be controlled by the emitter, check whether the battery contacts are normal and whether the power is sufficient. Replace the battery promptly when it is out of power. Insensitive remote control may be due to environmental interference or low battery. Remove the battery when the device is not used for a long time. Wire strictly in accordance with the parameters indicated on the labels. Failure to do so may shorten the device's lifespan or cause 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 using the remote control. The receiver beeps when the remote is pressed, which may be noticeable. Ensure there is enough space in the fan canopy or install the receiver nearby.
