Cautions: - If the new device cannot be controlled remotely, check whether the barcodes on the emitter and receiver match, whether the indicator light on the emitter is functioning, whether the receiver’s cable is properly connected, and whether the buzzer emits a single beep when powered on. - If the receiver does not respond to the emitter, verify that the battery contacts are clean and secure, and that the battery has sufficient charge. Replace the battery promptly when depleted. - Reduced remote control sensitivity may result from electromagnetic interference or low battery power. - Remove batteries if the remote will not be used for an extended period. - Wire connections must strictly follow the specifications indicated on product labels. Incorrect wiring may shorten the device’s lifespan or cause immediate malfunction. - The antenna must not be connected to any other wires. - If the fan has a code switch, set the fan speed to the highest setting before using the remote. - The receiver emits a beep upon each remote button press, which may be audible in quiet environments. Ensure adequate space inside the fan canopy or mount the receiver beside it as needed.
