Have a CPAP Machine? Beware of GAME OVER

Never heard of a unit having an expiration date programmed into it. My last ResMed unit was displaying that the last time that it was in use was 1999. My doctor went nuts until I reminded him that the machine wasn’t manufactured until 2010 so something was wrong with the memory. Usually you are required to have a yearly checkup which also includes the machine so if there was truly an expiration date your doctor would have mentioned it.
