When this happens, this means the battery disconnecting from the Sentinel.
This can happen when the plastic of the Sentinel expands due to heat, which can happen during transit.
A quick and easy fix is putting something small, like a folded piece of paper, on top of the battery inside the Sentinel. For help on how to open up your Sentinel, please see How to open up your SentinelX
This will cease the constant disconnections and beeping.
We hope this helps! If this doesn’t help you, please reach out to us and we will be happy to get you the help you need with your SentinelX.
