I think machine settings are tied to a machine serial number with the intent of preventing accidentally giving a patient the wrong SD card with wrong therapy settings. ergo, you'll have to program a new machine manually.
INFORMATION ON APNEA BOARD FORUMS OR ON APNEABOARD.COM SHOULD NOT BE CONSIDERED AS MEDICAL ADVICE. ALWAYS SEEK THE ADVICE OF A PHYSICIAN BEFORE SEEKING TREATMENT FOR MEDICAL CONDITIONS, INCLUDING SLEEP APNEA.

BTW, SleepyHead will display the most important settings on the old SD card if you've used it in the machine. You'll have to put it into the new machine manually from the clinician's menu.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
WELCOME! to the forum.!
Good luck on getting your new machine set up.
