Issue:
Looking for some of the behaviors of the HMIG5U/HMIG5U2 as the temperature goes beyond the suggested operating temperatures.

Product Line:
HMIG5U, HMIG5U2

Resolution:

The HMIG5U has a maximum operating environment temperature of 60 degrees Celcius.

When the HMIG5U is used in an operating environment temperature greater than what it is rated for, the following occurs:

at 65 degrees Celcius, the screen brightness becomes a little dark
at 70 degrees Celcius, the screen brightness becomes even more dark
at 75 degrees Celcius, the screen brightness is completely dark
at 80 degrees Celcius, thermal shutdown occurs.
