Notes and Cautions
The notes and cautions in this manual are categorized using the following symbols.
Improper handling or use can lead to injury to the user or damage to the
instrument. This symbol appears on the instrument to indicate that the user must
refer to the user’s manual for special instructions. The same symbol appears
in the corresponding place in the user’s manual to identify those instructions.
In the manual, the symbol is used in conjunction with the word “WARNING” or
“CAUTION.”
WARNING Calls attention to actions or conditions that could cause serious or fatal injury to
the user, and precautions that can be taken to prevent such occurrences.
CAUTION Calls attentions to actions or conditions that could cause light injury to the user
or damage to the instrument or user’s data, and precautions that can be taken to
prevent such occurrences.
French
AVERTISSEMENT Attire l’attention sur des gestes ou des conditions susceptibles
de provoquer des blessures graves (voire mortelles), et sur les
précautions de sécurité pouvant prévenir de tels accidents.
ATTENTION Attire l’attention sur des gestes ou des conditions susceptibles de
provoquer des blessures légères ou d’endommager l’instrument ou les
