If no visual alerts are visible, then it may be a Bluetooth pairing issue between the S2 and S3. Please read this article on how to pair S2 and S3, linked below [https://support.siera.ai/kb/how-to-pair-s2-and-s3-or-access-control](https://support.siera.ai/kb/how-to-pair-s2-and-s3-or-access-control?hsLang=en). Once the Bluetooth pairing is done, recheck for alerts on the screen. If the alerts do not re-appear on the screen after Bluetooth pairing, please contact support. 2\. The visual alerts could also be missing due to other power failure related issues. Please refer the article below for determining the root cause of the issue and contact support@siera.ai for further assistance.
