Thank you very much for your help Sierra. I left the machine on all day yesterday and when I got back home, I noted the signal bars were now green and brighter. Am in the UK. So it seems the machine had not connected yet. I will get hold of the SleepyHead to get more detail on my treatment.
Can someone help to know what the problem is with my Airsense 10 machine which I just started using 3 days ago why it is not transmitting data. The machine is not set to aeroplane mode. The only thing I noted is that the signal bars are grey in colour and not as bright as other text on the CPAP screen. Do these signal bars look brighter if they connect to a local WIFI?
