Note 3: Slight background color changes are allowed depending on ambient temperature.
This phenomenon is reversible.
Note 4: High temperature operation assumes the use of an enclosure that properly directs the
fan airflow
Note 5: Upper operating temperature limit of 60°C is without solar loading.
Reference to "room ambient" is interpreted as 20°C - 25°C [68°F°- 77°F] and applies throughout this
specification unless otherwise noted.
For product reliability predictions, the assumed temperature profile is:
