Therapy data card FAQs
Do you have questions about the data card used in your device? Find the answers to your most frequently asked questions about device data here.
Which SD cards can be used with S9™ therapy devices?
We recommend using the SD (Secure Digital) cards that were supplied with your S9 therapy device by your care provider or equipment supplier.
Why do you recommend only using SD cards supplied by ResMed?
You should use an SD card that has been supplied by ResMed as these were validated to meet the safety standards legally required.
ResMed has selected several SD cards that meet the necessary safety requirements (e.g., IEC 60601-1) and supplies these with the therapy device or as accessories. Not all SD cards on the market meet the clearance requirement or have been tested and validated to work with S9 devices.
How much storage does the S9 therapy device use on the SD card?
This varies depending on the size of the card. A 1GB SD card easily stores 365 days of usage data, 30 days of detailed data, and seven days of high-resolution data.
Can I use miniSD or microSD cards with my S9?
No. While these SD cards, used with an adapter, would work with an S9, they have not been shown to meet the IEC 60601-1 medical electrical equipment safety requirements for this therapy device. As a result, ResMed recommends that they should not be used.
Can I use SDHC, mini SDHC, micro SDHC, or SDXC cards with S9 therapy devices?
No. Secure Digital High Capacity (SDHC) cards, as well as mini and micro SDHC cards, and SDXC cards, do not work with S9 therapy devices.
Which SD speed classes work with S9 therapy devices?
The SD Speed Class is marked on most SD cards. Class 2 has a guaranteed transfer speed of 2MB per second; Class 4 provides 4MB; and Class 6 provides 6MB. Note that while S9 therapy devices will work with SD cards at these speeds, only ResMed-supplied SD cards should be used.
How do I remove the SD card and insert a new one?
To remove a SD Card, you need to push the SD card in to release it, and then remove it. To insert a SD Card, push the SD card into the device until it clicks.
We recommend that you insert the SD card when the device is not turned on, or alternately, when it is powered but not delivering therapy. If the card needs to be removed to check data, the recommended time to remove the SD card from the device is at least two minutes after stopping therapy.
I have the following messages appearing on my device screen: “Invalid SD Card, erase card data? Yes/No”, or “Data rewriting to SD Card, press yes to continue”. What should I do?
In this specific situation, the SD card contains unrecognisable files. You can simply turn the dial to select “Yes”, and your summary therapy data will be automatically rewritten to your SD card. If this message regularly appears, please make sure that you are not using the card in any other device (eg: laptop, camera, …), or unplugging your device too rapidly after stopping therapy (2 minutes minimum). If this does not solve your issue, we recommend you contact your care provide or equipment supplier.
