A person I ran across has disassembled the Resmed AS 11. Once the top of the AS11 is removed the electronics are available. He instructed me that the black bar on the right of photo is the cellular antennae. So, it appears disconnecting the antenna would stop the cellular transmission. (As always attempt this at your own risk - it will also void your warranty.)
Has anyone performed a tear down that shows where inside to disconnect the cellular device that sends report to cloud?
