I'm reaching out regarding a specific issue with one of the fingertip pulse oximeters we received. It has come to my attention that the device is not providing glucose readings as advertised, which is quite concerning.

Additionally, any troubleshooting steps or guidance on how to address this issue would be greatly appreciated. It's important for us to understand whether this is a common problem or if it might be related to the specific unit in question. Your prompt response on this matter would help us move forward effectively. Thank you for your assistance!
