No, you can't use SleepyHead because it won't work with the M Series smart cards. SleepyHead only works with the machines that use the SD cards. Should you get a new PR System One machine or ResMed S9 full data machine....you can for sure use SleepyHead safely and not worry about it messing with the data on the SD card.
At this point M series machine users have nothing to gain using any new software. You could use the newer Encore Viewer 2.0 or Encore Pro 2.4 but since the M Series machine do not gather the new information shown on the new reports..the reports don't change. I know this because I used a M series machine until April of this year..I used Encore Viewer 1.0 and Encore Pro 1.8 in the past and last January I got the new versions of the software and the reports didn't change one bit.
