* To charge the remote with solar energy, set the TV remote down with the solar panel facing up. Place it in your living room while your lights are turned on, or you can place it near a window where it will soak in natural sunlight.

* In case the remote's battery is depleted, you can charge it using a USB-C cable. To check the remaining battery level of the remote control, refer to the TV Menu (Settings > General & Privacy > Power & Energy Saving > Available Remote Battery).
