Caution
If the absolute maximum rating for any of the above parameters is exceeded even momentarily,
it may adversely affect the quality of this product. In other words, these absolute maximum
ratings have been set to prevent physical damage to the product. Do not use the product in such
a way as to exceed any of these ratings.
