Cautions: If the new 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 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 is making proper contact and whether the power is sufficient. Replace the battery promptly when it is depleted. Insensitive remote control 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 indicated on the labels. Failure to do so 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 using the remote control. The receiver emits a beep when the remote is pressed, which may be noticeable. Ensure there is sufficient space in the fan canopy or install the receiver nearby.
