Cautions: If the device cannot be controlled remotely, check that the barcodes on the emitter and receiver match, the emitter’s indicator light is functioning, the receiver’s cable is properly connected, and the buzzer emits one beep when powered on. If the receiver does not respond to the emitter, verify proper battery contact and sufficient power; replace batteries promptly when depleted. Reduced remote sensitivity may result from environmental interference or low battery. Remove batteries if the device will not be used for an extended period. Wire the device strictly according to the specifications indicated on the labels—improper wiring may shorten device 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 to the highest speed before using the remote. The receiver emits a beep when a remote button is pressed; this sound may be audible in quiet environments. Ensure adequate space inside the fan canopy or mount the receiver externally if necessary.
