Relative humidity
Operating
The maximum vibration specification of an operational system is 0.26 Grms at 5 Hz to 350 Hz (all operation
orientations).The maximum vibration specification of a nonoperational system is 1.88 Grms at 10 Hz to 500 Hz for 15
min (all six sides tested).

Storage
The maximum shock specification of an operational system is six consecutively executed shock pulses in the positive
and negative x, y, and z axes of 40 G for up to 2.3 ms. The maximum shock specification of a nonoperational system is
six consecutively executed shock pulses in the positive and negative x, y, and z axes (one pulse on each side of the
system) of 71 G for up to 2 ms.

Storage
The maximum altitude specification for an operational system is 3048 m (10,000 ft). The maximum altitude
specification for a nonoperational system is 12,000 m (39,370 ft).

If the operating temperature of a system is up to 35°C (95°F), the maximum temperature is reduced by 1°C/300 m
(1°F/547 ft) above 950 m (3,117 ft). If the operating temperature of a system is 35 °C–40 °C (95 °F–104 °F), the
maximum temperature is reduced by 1°C/175 m (1°F/319 ft) above 950 m (3,117 ft). If the operating temperature of a
system is 40 °C–45 °C (104–113 °F), the maximum temperature is reduced by 1°C/125 m (1°F/228 ft) above 950 m
(3,117 ft).
