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 a single 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 electromagnetic 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 labeled on the unit—improper wiring may shorten its 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 remote control. The receiver emits a beep when a remote button is pressed; ensure adequate space inside the fan canopy or mount the receiver externally as needed.
