If you have the current Nitelog program and would like to download the manual, please visit www.hdmusa.com  and hover on the Support Tab, then click on Software and User Guides.  Scroll down and click on Software and Firmware Downloads. You will see the Nitelog mobile app for both iOS and Android there.

You can also visit breas.us and click on Support which will open another menu-Z1 & Z2 Resources, click on CPAP User Guides and Software.  There you will find a selection of helpful materials to download, including our Z1 and Z2 User Manuals and our current Nitelog App Manual.

We are currently experiencing difficulties connecting Nitelog with the new iPhone 11 from Apple and the Samsung 10. We are diligently working to get this resolved ASAP. Older versions of Apple’s iPhone and Android phones are still working with Nitelog. 

We appreciate your patience.
