Always keep your TEU-LIGHT firmware updated to the latest version.

If there is a firmware update when you connect your TEU-LIGHT to the app,

a “Firmware Update” button will appear.

Press the “Firmware Update” button to update your light stick.

Make sure to check whether your light stick’s firmware needs to be updated before any TREASURE concert or fan meeting.

By doing so, you can enjoy the newest songs and concerts together with your light stick.
