August 2, 2018- FIRMWARE UPDATE NEEDED FOR SOME DEVICES – Fault Code 66 – Z1 Auto Firmware v2.1.0.5

This firmware change is for Z1 Auto CPAPs (black devices) with lot codes between A182602-A182901* which were manufactured between June 28, 2018 and July 25, 2018. You can find the date of manufacture and the lot codes on the back of the device.

This firmware version corrects an issue in Firmware v2.1.0.6 which causes an Error 66 message when connecting to Nitelog via Bluetooth and shuts off the device. This is easily corrected by power cycling the device by unplugging and replugging the power cord to the device. It does not harm the device. But if you want to use Nitelog, you must install Firmware v2.1.0.5.

*Affected lots A182602, A182603, A182604, A182605, A182701, A182801, A182802, A182803, A182804, A182901.
