Legal notes
Warning concept
This manual contains information which you must observe in order to ensure your own personal safety, as well as
to avoid material damage. The notices referring to your personal safety are highlighted in the manual by a safety
alert symbol, notices referring only to equipment damage have no safety alert symbol. These notices are graded
according to the degree of danger as shown below.
DANGER
Indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
Indicates that death or severe personal injury can result if proper precautions are not taken.
CAUTION
with a triangular safety alert, indicates that slight personal injury may result if proper precautions are not
taken.
CAUTION
without triangular safety alert means that there can be damage to property if the corresponding safety
measures are not followed.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one level of danger is simultaneously applicable, the warning notice for the highest level is used. If a
warning notice is used with the safety alert symbol to warn against injury, this same notice may also include a
warning regarding property damage.
