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.
