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 securely connected, and whether the buzzer emits a single beep upon power-on. If the receiver does not respond to the emitter, verify that battery contacts are clean and secure, and that battery power is sufficient. Replace batteries promptly when low. Reduced remote sensitivity may result from environmental interference or low battery power. Remove batteries if the device will not be used for an extended period. Wire the device strictly according to the specifications listed on the labels; incorrect wiring may reduce device lifespan or cause immediate failure. The antenna must not be connected to any other wires. If the fan has a code switch, set it to the highest speed before using the remote control. The receiver emits an audible beep when the remote button is pressed. Ensure adequate space inside the fan canopy or install the receiver accordingly.
