[Equipment] Buying Used ResMed "Floor Demo Model" - Limitations?

[tehsygi]

I purchased a used "floor demo model" ResMed AirSense 10 AutoSet unit from a local CPAP retail store. It had been used as a showcase device for demonstration. The vendor sanitized the machine, and it arrived in "like new" condition.

• When I purchased it (at a steep discount), the vendor noted one caveat: "Note: This device has no connection to ResMed AirView." (Presumably, this is related to being a floor demo model.)  That's fine for me; I don't need to give access to a clinician.
  
• During my initial setup, the device successfully connected to the cellular network. I switched it to airplane mode immediately after.  
  
• I tested and confirmed that the device properly records data to the SD card, viewable in OSCAR and ResScan.
  

Questions!

1. Is anyone familiar with ResMed devices sold in this "former store demo model" condition?

2. If I turn off Airplane Mode and allow the AirSense to connect to the cellular network, is there any risk that ResMed might remotely disable or deactivate this device for being a store demo unit?

3. Is it a bad idea to attempt to add this device to myAir so that I can view basic stats in the ResMed myAir app?  (This might fail, of course, since AirView is presumably prohibited.)

Thank you!

Hello, Your concerns are not warranted. If you received a good deal on the purchase, good for you.

I imagine your used unit has very few hrs. These units are vulnerable to dusty environments. Dust kills the bearings and makes these units noisy. You probably don’t need to worry about that.

You should still be able to sign up to my Air. With SN on back of machine.

And your last ?. Nobody is going to mess with your machine remotely.

Congratulations on getting a good deal.

Out of curiosity I Googled "AirSense 10 Autoset demo" and came up with an online store based in Pennsylvania, USA (not on CPAP supplier list for this forum). On the ad page near the bottom was the note regarding linking to MyAir. Interesting and I wonder why a demo unit would different than other units? You said you bought yours locally (Colombia) which is pretty far away from Pennsylvania.

Enjoy the new machine and the savings you got!!!

Thanks for the feedback.

Interesting. That vendor specifically calls out ResMed myAir, not ResMed AirView. It could be the same limitation. And yeah, different vendor in a different country

My hunch is that ResMed allows retailers to purchase one or two "store demo units" at a steep discount. And, as part of the demo unit discount, those device IDs are permanently blocked from ResMed cloud services (myAir and ResScan) to discourage resale of used demo units to actual customers. From a business perspective, they don't like people buying used CPAPs... and certainly not used CPAPs that they sold at a steep discount.

I don't know whether (A) they block these devices from cloud services to simply "discourage" demo unit resale or (B) they truly contractually prohibit retailers from reselling those demo units. B is the possibility that worried me.

I have a quick update, in case anyone is curious or stumbles upon this thread.

I tried adding the AirSense 10 AutoSet store demo unit to ResMed myAir.  myAir successfully allowed registration and recognized the device model correctly.  However, even after rebooting my AirSense 10 and using it for several days, data never syncs to myAir.

The AirSense device itself shows no symptoms of this upload failure. It shows 5 bars (-45dBm) of cellular service with a local provider.  There is one curious anomaly about this device, though:  Unlike another AirSense 10 CPAP unit that I've used, the modem serial number is different from the device serial number.   The modem serial number is the one shown in the UI (Settings / My Options: About: Internal Modem: SN), while the device serial number is the one printed on a sticker on the back of the unit (and embedded in the SD card data).

Conclusion: If you buy a ResMed device that was a store demo unit, it will not send data to ResMed AirView OR ResMed myAir. The data is fully available via SD card, though.

You cannot draw the conclusion that the data is not being *sent*. Nor can you draw the conlucsion that because the data is not available in myAir it is also not available in AirView.

Just out of curiousity, have you have checked the number of therapy hours recorded on your machine?  It reminded me of someone who purchased a lightly used executive driven "demo" car from a new car dealer's lot.  Upon taking ownership, and arriving with a late report, they discovered that it was a return from a car rental agency.

At initial unboxing, the reported lifetime therapy hours were less than 100 hours. I don't think that number can be trusted, as there seem to be many ways to reset the data.

But this machine was in immaculate condition. The original stickers on the top and the screen ("screen protector" lol) were even untouched.  If this really was a "used and refurbished" unit, they went to extraordinary lengths to hide it.

[OpalRose]

If the unit was refurbished, the vendor would have place a "refurbished sticker" on the bottom or back of unit.

It's probably just a floor demo. Seems like you have a good unit.

I was told, when buying my used Airsense 10 Autoset that it was an imported machine and unable to connect via modem to Resmed UK.  It is also a 2G model and I was  not sure 2G service was still available in the UK.

But I noticed later that it was indeed making a live conneciton to the Vodaphone UK cellular network.

I also read that if a machine does not connect to the server for a period of six months or more, then ResMed 'turn off' the data connection to that machine in order to save costs...

As an experiment, I registered the serial number of my machine, and a day or so later, was successfully able to use the MyAir phone app.

Subsequently,  I also tried the PC-based Rescan app and, when saving settings it told me that it was connected to my Airsense (which was unplugged at the time)  From this I surmised that   Rescan was able to communicate  directly wih the Airsense 10 via the cell network ie reading and writing.

I imagine this might also include  firm-ware updates?

Could the above  be true for a used demo machine?
