tion or statement, if not strictly observed, could result in personal injury.
A caution is used whenever an operation or maintenance procedure, practice, condition or
statement, if not strictly observed, could result in damage to the equipment.
NOTE: A note is used where it is essential to highlight a procedure, practice, condition or state-
ment.
The following are examples of the symbols that are used in this manual for an electrostatic
damage caution and laser radiation warning.
