Between 5 – 30°C [41 - 86°F], the unit can be operated at a
relative humidity of up to 80%. At temperatures between
31 - 40°C [87.8 - 104°F], the humidity must decrease propor-
tionally in order to ensure operational readiness (e.g., at 35°C
[95°F] = 65% humidity; at 40°C [104°F] = 50% humidity). The
unit may not be operated at temperatures above 40°C [104°F].
