Sorry for the inconvenience caused. Our engineers have identified this issue and are currently testing it. Please be patient and thank you for your support.

Sorry for the inconvenience caused. Placing it in the cabinet will affect the transmission of infrared signals. Currently, U2 does not provide an IR repeater. Using an IR repeater to enhance the infrared signal will still block the transmission of infrared signals.

Sorry for the inconvenience caused. U1 has been updated to U2 and the infrared distance has been added. The other buttons have not been changed, and your issue has been reported to the engineer for repair.
