I have a brand new APEX XT Fit Sense machine which is supposed to "sense" elevation changes and make adjustment automatically, to 8000' above sea level.
What does the machine actually do to adjust to higher elevation?
I am going to Cusco Peru in May and plan on spending several nights at 11,000'. What can I do to the machine (if anything) when I sleep above 8000'?
Thanks in advance for any recommendations.
