Operating and recommended ranges refer to the ambient air temperature and humidity measured 19.7 in. (50 cm) from
the front of the air intake cooling vents.

For each 1000 feet (305 m) increase in altitude above 10,000 feet (up to a maximum of 15,000 feet), subtract 1.5° F
(0.83° C) from the upper limit of the operating and recommended temperature ranges.
