This Motor Life Exceeded message is a warning that appears after approximately 23,000 hours of use to notify patients their CPAP machine is passed its used-by-date. This message is meant to encourage users to start thinking about buying a new machine. Patient safety is the reason for the message. Your CPAP machine will continue to provide you with therapy, but the message will increase in frequency and your machine has the potential to fail. The message can be ignored but cannot be turned off.
