RE: Reset usage hours
Thank you for your info. I bought the machine in the USA and it is new. I am the only user. I assumed that the hours and events would clear on a daily basis automatically. The USA time runs from noon to noon and I do not know if UK is the same. I will order the manual you have suggested. Thank you again.
RE: Reset usage hours
Hi Kathy. The machine retains all the summary information internally, forever. The more detailed high resolution data (eg breath-by-breath pressure, flow etc) is not stored internally but written to the SD card.
Each day at noon (according to the machine's internal clock) the machine resets your daily data so that the AHI, usage hours etc are correct for each 24 hour period. The internal clock needs to be set to UK time, and the manual will have instructions on how to do that.
RE: Reset usage hours
Hello DeepBreathing,
Yes I thought that was what would happen. I just wanted to clear the daily display info and since I was running on USA time until a couple of hours ago when I changed to UK time, I guess it won't clear until I go through a 24 hour cycle.
Thanks again for taking time to answer. Much appreciated.
RE: Reset usage hours
The info on screen resets when the machine's internal clock hits noon.
Since the UK is 5 to 8 hours ahead of the US, you should be able to move the internal clock ahead the required number of hours.
(I assume you have done this.)
Your displayed stats should reset the next time you cross local noon.
Those who go from the US to say Australia require a move backwards. This sometimes get complicated because the date may not be set to a day that contains any data. In that case, a reset of data is required.
Best to have the manual as OpalRose has suggested.
Best Wishes,
Mongo
RE: Reset usage hours
I would suggest that you obtain a SD Card so that you can export data to SleepyHead software - you don't need to do this daily, the SD Card saves all days. You can also register on myair.resmed.com and get very basic information from previous nights that is uploaded before noon each day. No need to reset.

MyAir may not work in the UK. It's my understanding that the cellular modem is CDMA; and the UK telecoms are GSM.
RE: Reset usage hours
Thanks so much Mongo and yes I have already reset the internal clock. It should now clear tomorrow at noon. I do have an SD card CatNap.
Thanks to all who took time to answer my query. I really appreciate it.
Take care,
Kathy
RE: Reset usage hours
My experience has been that the usage hours does not clear until you actually start a new session - that is, put the mask on and start the blower. I don't know if running the 'mask fit' function will do that or not.
It's not a major thing, just a minor correction.
Oh, it will start accumulating hours again if you sleep past 'machine noon'. My clock runs slow, so if I sleep until 12:30, I'll see a 20 or 25 minute session for 'today'; it's startling the first time you see it.
