Why just 30 days detailed records? The rest are summaries

[welshmike]

I've been downloading the data recorded by my ResMed S9 Autoset every day and have been viewing the overnight breathing records.
However only the detailed graphs are available for the first 30 days I have used the device; the rest being statistical summaries.
Is there a way of getting the device to start producing detailed results again?

In order to get ALL of your available data into Sleepyhead or ResScan, you need to download the card every 7 days. Some flow graphs are written over after 7 days, other detailed data written over after 30 days.

So just download your card once a week, be sure if using ResScan that you have checked appropriate boxes for "ALL data" and "high rate data" etc to get everything...
