Smart Card data retention ?

Post by Pirate » Thu Sep 14, 2006 11:16 am

I have a respironics apap w/ cflex. Does anyone know how many days of data the smart card will retain before it starts to overwrite data? Stated otherwise, how many days can I go without downloading without loosing any data?

detail data about 6 days before it starts to overwrite

I get 7 "days" so download once a week. BUT The device seems to record detailed data as sleep periods not days. On the rare occasion I have napped the device recorded detailed data for 6 days plus the 1.2 hr nap. In the compliance data it showed as 7 days with 2 green blocks that 24 hour period.
