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. When 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 low. Insensitive remote control may be caused by environmental interference or low battery. Remove the battery when the device is not in use for an extended period. Wire the device properly according to the parameters listed on the labels. 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 for remote control operation. The receiver will beep when the remote is pressed, which may be noticeable. Ensure there is sufficient space in the fan canopy or position the receiver accordingly.
