The ResMed SD card stores the data gathered from your AirSense 11 devices allowing you to easily transfer data from your device to your PC. Your care provider may ask you to send the SD card by mail or to bring it in.
To use the SD card to record your sleep data, remove the SD cover. The LED indicator on your device is blue when data is written to the SD card.
Do not remove the SD card from the device when the SD light is flashing.
Note: The SD card should not be used for any other purpose as it may corrupt therapy data stored on the card.
