S9 Autoset internal clock?

I'm guessing it's unhappy about setting the time back to a time for which there's already data.

Good idea, but it didn't work. At 10pm I tried to set it for 10am (I had awakened at 8:40am this morning) but the S9 wouldn't have it; still got the same error message as before.

I was afraid if I wanted to give them data in any form besides actually handing over my card that they wouldn't know how (or wouldn't be able) to import it into their software, so I didn't want to risk erasing data in case the next time I put card in machine it erased the compliance data from the card.

(I'm not really sure which data the S9 reads and writes to and from the card, and what would happen if you have usage data on the card which is then erased from machine).

Just make a copy of the SD card and send them the copy. Resscan is not particular about how the data is placed on the SD card as long as it is all there in the correct root and DATALOG folders. The S9 wants data in the proper location on the SD card, which a PC doesn't do, or it'll reformat the card so do not send the card from the machine to the DME. Proper location means specific cluster regions, not folder structure.

When I try to change it to the correct day, the message says, "Invalid date/time, data exists for this time period." And it won't let me do it. I've read that you have to erase all data in order to reset the date.

It's not just unhappy, it gets downright angry!! The only way to get the S9 to accept a reset back to the previous date would be to not use the machine for over 36 hours so no data is recorded for the previous date. Your suggestion for one hour resets will work until you get to between 12 and 1 am. A one hour set back requires a date change, and that is the problem.

A one hour, or more, set back can be accomplished AFTER therapy mode is turned off and BEFORE noon, or AFTER noon and BEFORE the machine is turned back on to therapy mode. As soon as the machine is turned on to therapy mode data recording begins and you cannot set the time back into a time span wherein data was recorded.

I think I set my S9 clock forward and then had 1 hour of blank data from 2-3am. It seems some others did too,
This time I think I'll wait until the next day to see if it changes on it's own.

Stay tuned. I'll post some instructions in a week or so. I'll also check on the leap year issue. See the thread on daylight savings time.

I was just thinking of waiting until the DME asks for my card, which should be in less than a month. When I send in the card, I can erase all data and then reset both time & date on my S9 with no issues, I hope?

Since the DME will have all of my up-to-date usage info, it will make no difference if I erase all data from machine at that point, right?

Are you sure the message indicates the data will be erased from the machine? I didn't know it was possible to erase the data from the machine.

I haven't done it before but it's in the clinician's menu under "options". Someone else posted here some time ago that it will erase all usage data from machine except for blower hours (which makes sense, since if you buy a used machine you want to be able to check how many hours are on the machine).

I have the S9 Autoset with dehumidifier and I cannot find any reference to setting the clock in any manual I have. Can someone please tell me how to get to clock setting? When I look at info in Res Scan program, time is always off by 1 hr or so. It shows usage starting at 0030 hrs instead of 2330 hrs. Any info who be great. I have to print out my data because Docs system cannot read SD card. They need computer geeks to re-install program. That, or I change doctors....

I already have enough clocks in the bedroom--don't really care what time Resmed thinks it is.

Do you know how to get into the clinician's menu on the CPAP?

Be careful, the S9 has a tendency to want to delete all data from the SD card if you change the time.

Do you use SleepyHead?

Assuming you've found out how to get into the settings menu, here's everything you need to know about changing the time in an S9.

Do you by chance have a spare SD card? If you put a blank SD card in your machine, you could then change the date and time. The new SD card would show the compliance data from the day you wiped the machine data, but the old SD card would show the older compliance data. You could take one or both of the SD cards to whoever checks your compliance data.

You might want some of the other folks who are more familiar with this machine chime in one way or another, as I've had my S9 for less than a month, and am not that familiar with the in's and out's of the machine.

Changing the time doesn't wipe the summary data. I am not sure about the daily detail. Both machines I have gotten from the DME have been off by an hour. Perhaps the time was programmed in during Daylight Savings Time at the distributor that sends them to the DME.

I don't have an S9, but from the reports here, there is a somewhat confusing set of conditions on which it will wipe out the data. It has to do with whether you're trying to overwrite data by going back to a previous day, or if you're trying to set it back to a time when you already have data. An example would be if you're trying to adjust daylight savings time less than an hour after you just turned the machine off.

Sometimes, you're fine, sometimes your data is gone, depending on your timing.

I don't know for sure whether summary and compliance data gets wiped.
