If your remote control is unresponsive, please follow these simple troubleshooting steps to diagnose the issue.
①Unscrew the screw on the bottom of the remote control, and then replace the battery with a new CR2032；
②Perform the Infrared (IR) Signal Test
This quick test uses your smartphone's camera to verify if the remote is emitting an IR signal.
- Open the camera app on your smartphone (the rear-facing camera typically works best).
- Point the top end of the remote control (the IR emitter) directly at the camera lens.
- Press and hold any button on the remote while looking at your phone's screen.
