Over-temp Condition

The display contains a temperature sensor which measures the temperature of the
circuit board at the lower left corner as viewed from the component side of the
board.
If the board temperature exceeds approximately 100C, the display will
automatically operate at its lowest luminance setting (as if LUM0 was low and LUM1
was high) to reduce the board temperature. At no point will the display be shut
down. The content of the pattern will be unaffected.
After surpassing 100C, once the board temperature drops below approximately 92C
or the power is cycled, the display will resume normal operation as defined by the
LUM0 and LUM1 settings. Typically, the 100C limit may be reached if the 12V input
power exceeds 6W when the ambient temperature for the display electronics is
85C.
