There must be one as SleepyHead s/w tells me the dates and times for events.
When I had a cellular modem I thought the clock was set automatically from the cell tower.
Now I don't have a modem, so there is no electronic connection that I know of. Is there?
Eventually the clock will drift and/or I might move to a different time zone.
So how do you set the clock in a CPAP machine?
