Warning Signs
Warning signs are shown throughout this manual in order to prevent injury to the user and/or material damage.
These signs are composed of a symbol and a message describing the recommended level of caution. The
following explains the symbol, its level of caution, and its meaning as used in this manual.
This symbol indicates the possibility of serious or fatal injury if the ETERNUS AF is not used
properly.
This symbol indicates the possibility of minor or moderate personal injury, as well as damage to
the ETERNUS AF and/or to other users and their property, if the ETERNUS AF is not used properly.
This symbol indicates IMPORTANT information for the user to note when using the ETERNUS AF.
The following symbols are used to indicate the type of warnings or cautions being described.
The triangle emphasizes the urgency of the WARNING and CAUTION contents. Inside the
triangle and above it are details concerning the symbol (e.g. Electrical Shock).
The barred "Do Not..." circle warns against certain actions. The action which must be avoided
is both illustrated inside the barred circle and written above it (e.g. No Disassembly).
The black "Must Do..." circle indicates actions that must be taken. The required action is both
illustrated inside the black disk and written above it (e.g. Unplug).
How Warnings are Presented in This Manual
A message is written beside the symbol indicating the caution level. This message is marked with a vertical
ribbon in the left margin, to distinguish this warning from ordinary descriptions.
An example is shown below.
