Display Installation Precautions

Temperature extremes can affect display quality. The display can become unreadable at temperature
extremes; however, this is only a temporary condition. The display will again be readable when
temperatures return to within operable limits.
The display update rate may increase at cold temperature extremes, but as with readability, normal
updating resumes when temperatures are within limits for full operability.
