I recently purchased a used S9 Elite for travel/backup that the previous owner said he used for about 3 weeks. The CPAP looks pristine with no wear and tear on the body and humidifier. I'm trying to access the menu that shows the total hours on the machine and after following the menu I can't seem to get to the info.
I start up the S9, press the push button and check mark button (lower button to the left of the spining push button) and enter the "Configuration" Menu. From here the directions say to press the "i" button to get to the device information. I can't seem to get past the configuration menu. The S9 did not come with an SD card so I grabbed an old 4gb one to see if maybe it needed a card, still no luck.
Any ideas?
Thanks!
