Corrective Actions
 Ensure that the ambient temperature falls within the
specified temperature range.
 Make sure that the ventilation holes are not obstructed.
 Remove any foreign objects from the heat sink and check
for possible dirt in heat sink.
 Provide enough spacing for adequate ventilation.
