How do I Make Manual Altitude Adjustment on a Resmed S8 CPAP?

The ResMed S8 CPAP series is built to travel with you. However, if you travel to places significantly higher (or lower) above sea level than your home, you'll need to make an altitude adjustment to the machine's programming. That's because higher altitudes have lower air pressure, and your CPAP machine needs to compensate for the difference. Making an altitude adjustment doesn't take very long to do, and it can make a big difference in the quality of your sleep when you're away from home.
