Operating Temperature	5oC - 35oC
Storage Temperature	-40oC to 70oC
Operating Humidity	15% to 80% (relative)

Storage Humidity	8% to 85% (relative), non-condensing at 40°C (104°F)

Acoustic Noise Emission:	(as defined ISO 7779)
	Sound level (LwA) ≤ 37 db (operating)

Operating Altitude	10000 ft (3100m) max
