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 cable is properly connected, and whether the buzzer emits a single beep when powered on. If the receiver cannot be controlled by the emitter, check whether the battery contacts are clean and secure, and whether the battery power is sufficient. Replace the battery promptly when 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 the device strictly according to the specifications listed on the labels; improper wiring may shorten 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 it to the highest speed before using the remote control. The receiver emits a beep when the remote button is pressed, which may be ble. Ensure adequate space in the fan canopy or install the receiver accordingly.
