normal operation or below -5℃ or exceeds 50℃ (14℉-104℉) for transportation
and storage. Humidity should be maintained between 50 and 80% for normal
operation, transportation and storage. Avoid environments where the equipment is
exposed to excessive shocks or vibrations.
At operating and non-operating, the warranted environments of temperature and
Humidity are as followings:
At operating : to 80% from +10°C to +31°C, and decreasing linearly to 50% from
+31°C to +40°C
At storage : to 90% from -5°C to 40°C, and to 30% from +40°C to
+50°C decreasing linearly to 50 percent
The warranted altitude is as following:
At operating : to 6,560ft(2,000m)
At storage : to 14,280ft(6,000m), non-operating
