Temperature
Operating 10°C to 35°C (40°F to 95°F) with a maximum temperature gradation of 20°C per hour
Storage –40° to 65°C (–40° to 149°F) at a maximum altitude of 12,000 m (39,370 ft)
Relative humidity
Operating 10% to 80% (noncondensing) with 29°C (84.2°F) maximum dew point
Storage 5% to 95% (noncondensing) with 33°C (91°F) maximum dew point
Maximum vibration
Operating 0.21 G at 5–500 Hz for 15 min
Storage 1.04 G at 2–200 Hz for 15 min
Maximum shock
Operating Half-sine shock 5 G +/- 5% with a pulse duration of 10 ms +/- 10% in operational orientations only
Storage Half-sine shock 30 G +/- 5% with a pulse duration of 10 ms +/- 10% (all sides)
Altitude
Operating 0 m to 3,048 m (0 ft to 10,000 ft)
For altitudes above 915 m (3,000 ft), the maximum operating temperature is derated 1°C per 300 m
(1°F per 547 ft)
Storage –300 m to 12,192 m (–1000 ft to 40,000 ft)
Airborne Contaminant Level
