No data from my S8 Elite Autoset II

I recently purchased a unit at the auction site. This is my first experience with a cpap machine. I dont know what I am doing wrong but I can not get any data from my machine each day. I check it in the morning and it always says usage of 2 hours. For each data point it says no data. I have only had the unit a week. The first time I used it there was data in the morning. Please give me some direction. Is the unit malfunctioning?

Once the clock ticks past 12 noon, data remains but can't be read off the lcd screen. So I would check your clock settings.

Sorry about being late on the reply. I checked the clock settings and they are correct. Still no data each morning.

Bodack, I just sent you a PM (private message).
