DR2- Replacement of The Replacement - Transfer of Data?

[Borderline99]

I've had my DR2 for 60+/- Days.... with a Wi-Fi SD Card installed. I noticed the Touchscreen was intermittently responsive and notified Respironics. They just sent a replacement DR2 and would like to perform the following:

1) Even though I transferred the SD Card from the old to the new, I'm not seeing any transfer of Stored "Use" Data..... I realize the actual USE Hours of the new device will now be Zero, but the Display does not show any past Details. I’m assuming there is no method to transfer the historical data.
2) I do use OSCAR and the Wi-Fi Card using Flash PAP continues to work flawlessly. I do use the DreamMapper on my Android also at times. I would like to Delete the old equipment DreamMapper is storing, as it now shows both my old System One and original DR2… and will also show the newly received replacement DR2 when I add it. I’ve just not been able to locate a DELETE option for the old equipment. Any idea where its hiding other than to uninstall and re-install the APP?

Thanks!

I don't know about the Android app, but within the settings of DreamMapper for a Windows PC the device information can be found. I'm pretty sure you can add or delete the Secondary device, but the Primary device I believe only your DME or maybe doctor can change via their Orchestrator software.
When I received my DS2 replacement for the DS1 the primary device changed from the serial of the DS1 to that of the DS2. My DME was the one that made the change.
