General guidelines or prerequisites:

• [Software Updates] Please upgrade both product firmware and mobile app to ensure the unit is running the latest features, control logics and stability optimizations. This also establishes a verified baseline before proceeding with further diagnostics. Firmware v4.3.0 and App v2.0.0 are the newest versions. If your firmware is older than v4.0.0, kindly check out the update guide first.
• [Self-Check Function] This capability has become fully-fledged since firmware v4.0.0. We recommend running a self-check in the Popur S7 App → device page → top-right icon for list of settings → Self-check → Start. You’ll be prompted with either an all-good result or the guided troubleshooting. Most problems can be identified automatically and solved quickly. The report can also be reviewed or analyzed by our engineers in greater depth.
• [Device UID] For technical assistance, kindly provide us with the unit identifier by pasting from the Popur S7 App → device page → top-right icon for list of settings → Technical info → tap the UID to copy the full character string. If the UID is not retrievable due to issues like connectivity, please tell us the email address of your app account.
