important operational and safety information.
A “NOTE” marks a short message to alert you to an important detail.
A “CAUTION” safety alert appears with information that is important for protecting your
equipment and performance. Be especially careful to read and follow all cautions that apply to
your application.
A “WARNING” safety alert appears with information that is important for protecting you, oth-
ers and equipment from damage. Pay very close attention to all warnings that apply to your
application.
The safety alert symbol, ç (an exclamation point in a triangle) precedes a general CAUTION

The electrical hazard symbol, Ó (a lightning bolt in a triangle) precedes an electric shock haz-
ard CAUTION or WARNING safety statement.
