Will not delete the previously recorded studies.' 'The ApneaLink can store several weeks of data. I couldn't through to the company but the center that's doing my study emailed me and said Thanks so much! I have tonight, tomorrow night and Monday night open to do the second test as I have it for the long holiday weekend here (Canada Day on Monday) so I'm hoping to get at least one more test in if possible but the first one was pretty good minus the sensor killing my finger because she told me to push my finger in so far that it pinched the tip all night and I woke up a lot because of it.) Maybe she meant that the data would be overwritten for the first night.Д¬an anyone confirm that data recordings for two nights can be saved on this device and that putting in fresh batteries for the second night doesn't affect the first recording?ДЄlso, if anyone knows, could you tell me HOW it retains the data without power when the batteries are removed? I know that with RAM, once power is removed, the data is usually wiped so this concerns me that maybe I didn't hear her correctly. I was told that for my second night, just take out the batteries, put new ones in and do the second test. I was told that the memory in it could 'hold 3 nights worth' of data, but I was looking up its specs on the manufacturer's site and it says it uses RAM (15 megs total). I just did one night's study with the ResMed ApneaLink (not the Plus, just the regular one).
