Alerts and notice signs

Four types of alerts are used in this manual. The alert type is closely related to the effect that 

may be caused if it is not observed. These alerts - from least severe effect to most severe 

effect - are:

NOTICE! 

Alert containing additional information. Usually, not observing a ‘notice’ does not result in 

damage to the equipment or personal injuries.

CAUTION! 

The equipment or the property can be damaged, or persons can be lightly injured if the alert is 

not observed.

WARNING! 

The equipment or the property can be seriously damaged, or persons can be severely injured 

if the alert is not observed.

DANGER! 

Not observing the alert can lead to severe injuries or death.
