setting time on encore viewer

I would like to know how to set the time on my auto cpap or encore viewer? So i could view the exact times i am sleeping. It would be helpful to know when i am waking during the night. Now the time encore viewer shows is not right.

Just get used to it.

The only way the time can be set is by sending it back to the factory or finding some rare DME location that has the special cable and software to do it.
The internal clocks are set at the factory to GMT. The time is then converted to your local timezone when the data is downloaded into your computer (using the timezone set in your operating system).
Even if you get it reset, it'll still keep losing time at the rate of about a minute (or more) a month.

The time is not in Encore Viewer. It is set in GMT in your CPAP. Your computer then converts it to what ever time zone you are in. The only way to correct it is to correct it in your CPAP which can only be done by sending it back to the factory. I have heard that some DME's have the program, card and cable to do it but I have not found one yet. The clock chip in the CPAP does not keep very good time. As they get older it gets worse because the battery gets weaker. The only fix for it that I know of is to offset your computer time for the amount it is off.

So on our Encore Viewer it's about 10mins off, shows machine turned on at 10:30PM instead of correct time of 10:45. We began cpap on 9/2/08(7months), so that's about right. So in about a year it will be about 15mins off,etc. And it will keep losing more time as time goes on? I don't like that!

I thought the time set itself according to the time on your computer, too. I know that my time was always off by an hour until a got a new computer and set the time to my time zone (my last computer was mistakenly set to Central Time, and I never changed it there because when I did, it changed all of my appointment times on my Palm Pilot?!). When I got a new computer, I was careful to set the time correctly, and my M Series Encore Pro reports have been using my real time ever since.

Sorry, Jerry, I misread your post. The time is set on the cpap machine at the factory, Encore Viewer is not the problem. Hope I've got it right now. Dori

After reading these posts I'm confused. OK, the clock on the Respironics units slowly lose time. But, you seem to be indicating that the clocks cannot be reset except by sending them to the factory? So what happens when the "on board" battery finally dies?

Is this a Respironics specific issue? Do we need to worry that when the internal battery dies that we will no longer be able to get useful information out of the PAP? If the internal clock battery finally dies, then I would assume that the data stored to the Smart Card would not have any useable "time stamp" and thus be almost useless and very difficult to manage with Encore. Is this right?

I have an older ResMed VPAP and I can reset its internal clock.

Has anyone had this problem with the battery actually being totally exhaused on a Respironics XPAP? If so, what happened? How long does the internal battery last?

Do we need to worry about this battery issue and "older" Respironics PAPs that we might pick up? Do other brands of XPAPs have this same issue?

If you have to send it back to the factory for a "fresh battery" and time adjustment, then how much does that cost? Is it covered by insurance? Has anyone ever done this?

Builta, good question. I don't know. I know there are lots of old Remstars around but I have never seen a post that the battery completely died. I know the battery in my computer that powers the clock chip has lasted 5 to 6 years. My Doc told me my battery in my Pacemaker would last around 5 years, hows that for a factory installation!! I have only changed one in all the years I have had a computer. Only the ones that records data even needs a clock chip. The only one I know that lets you set the clock is the ResMed. Ther may be others but I have not had enough experance with them to know. I know of a couple that got sent back for other things have had the clock reset but I don't know of any that have just been sent back just for that. Maybe someone who has had one longer than me might jump in and throw som light on this issue.

Lots of good questions that not many of us really know the answers to. There was a poster sometime back that stated that his data was showing a date back in (I believe) 1998. This would indicate that the battery was dead and the system reverted back to the BIOS date (to compare it to a similar computer scenario).

All of the times in my Legacy models vary from over 30 min. to 1 hr. and 45 min. slow. The oldest being from 2005.
It isn't just those models, but the M Series machines, too. They all have the same flaw.
From the pictures I've seen of machines that have been taken apart, the battery is the same wafer-type battery as goes in most computer motherboards......CR2032.

What it takes to reset the clock is a special cable with a smart card wired on one end and the other end connects to a computer serial port. The software is called "Unit Under Test" (UUT). It's almost impossible to find outside of a very few places that do this type of work. Apparently Respironics has had a tight control over who can get it. However, one of our forum members DOES have it.
