CAUTIONS

call attention to actions or conditions that can result in damage to the equipment or

in abnormal performance.

NOTE

NOTES

give important, additional information, explanations or recommendations related to the

appropriate topic or procedure.

WARNINGS

and

CAUTIONS

, like other safety instructions, appear within rectangles in the text

where they are applicable. Because of their importance, they are summarized in this Safety
