Z2 Auto Firmware 2.1.0.9 for iPhone 11 Users Trying to Connect to Nitelog

June 1, 2020 – Breas Medical announces the release of Z2 Auto Firmware 2.1.0.9.

Upgrade to the new firmware is not necessary unless you have an iPhone 11. It does not affect the performance or functionality of the Z1 or Z2.  All Z2 Auto CPAPs manufactured after  June 1, 2020 will have the new firmware already installed.
