Environmental

Operating	10% to 80% relative humidity (RH), with 26 °C maximum
	dew point.
Storage	5% to 95% relative humidity ambient with 33 °C (91 °F)
	maximum dew point.
Maximum vibration
Operating	0.26 Grms at 5 Hz to 350 Hz (all operation orientations).
Storage	1.87 Grms at 10 Hz to 500 Hz for 15 min (all six sides
	tested).

Operating	One shock pulse in the positive z axis (one pulse on each
	side of the system) of 31 G for 2.6 ms in the operational
	orientation.
Storage	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.
	Six consecutively executed shock pulses in the positive
	and negative x, y, and z axes (one pulse on each side of
	the system) of 22 G faired square wave pulse with
	velocity change at 200 inches/second (508 centimeters/
	second).
