Cautions: If the device cannot be remotely controlled, check that the emitter and receiver codes match, the emitter indicator light is functioning, the receiver cable is securely connected, and the buzzer emits one beep at power-on. If the receiver does not respond to the emitter, verify battery contact and charge level—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 printed on the labels; incorrect wiring may reduce lifespan or cause immediate failure. Do not connect the antenna to other wires. If the fan has a code switch, set it to the highest speed before using the remote. The receiver emits an audible beep when the remote button is pressed—this sound may be noticeable. Ensure adequate space inside the fan canopy or mount the receiver accordingly.
