Mitsubishi Electric Corporation puts the maximum effort into
making semiconductor products better and more reliable, but
there is always the possibility that trouble may occur with them.
Trouble with semiconductors may lead to personal injury, fire
or property damage. Remember to give due consideration to
safety when making your circuit designs, with appropriate
measures such as (1)placement of substitutive, auxiliary
circuits, (2)use of non-flammable material or (3)prevention
against any malfunction or mishap.
