1Use the formulas in Figure 9 to calculate the maximum operating temperature (in °C) for a given altitude. Use the first formula if the altitude is stated in meters; use the second formula if the altitude is stated in feet.

2Use the formulas in Figure 10 to calculate the maximum operating temperature (in °F) for a given altitude. Use the first formula if the altitude is stated in meters; use the second formula if the altitude is stated in feet.
