2.3 Certification
This product has the following approvals:
■ This equipment has been tested and found to comply with the limits for a Class B digital de‐
vice, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
─ Reorient or relocate the receiving antenna.
─ Increase the separation between the equipment and receiver.
─ Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
─ Consult the dealer or an experienced radio/TV technician for help.
■ This device complies with part 15 of the FCC rules. The operation is subject to the following
two conditions:
─ this device may not cause harmful interference, and
─ this device must accept any interference received, including interference that may cause
undesired operation.
■ This device fulfils the provisions of the Industry Canada Licence, with the exception of the RSS
rules. The operation is subject to the following two conditions:
─ this device may not cause harmful interference, and
─ this device must accept any interference received, including interference that may cause
undesired operation.
In order to ensure permanent compliance with the FCC rules, unless explicitly approved by
the authority responsible for compliance with the provisions, no changes must be carried out
(for example: when connecting to computers or peripheral equipment use shielded cables on‐
ly).

2.5.1 Warnings
Warning notices indicate dangers that may result in injury when disregarded.
2 Regarding this document
2.3 Certification
6User Manual Controller
SIGMA CONTROL 2 SCREW FLUID ≥4.1.X No.: 9_9450 08 E

Warning notices indicate three levels of danger identified by the corresponding signal word:
Signal term Meaning Consequences of non-compliance
DANGER Warns of an imminent threat of danger Will result in death or severe injury
WARNING Warns of possible danger May result in death or severe injury
CAUTION Warns of a potentially dangerous situation May result in a moderate physical injury
Tab. 5 Danger levels and their definition (personal injury)
Warning notices preceding a chapter apply to the entire chapter, including all sub-sections.
Example:
DANGER
These show the kind of danger and its source.
The possible consequences of ignoring a warning are shown here.
If you ignore the warning notice, the "DANGER" signal word indicates a lethal or severe in‐
jury will occur.
➤ The measures required to protect yourself from danger are shown here.
Warning notes referring to a sub-section or the subsequent action are integrated into the procedure
and numbered as an action.
Example:
1. WARNING!
These show the kind of danger and its source.
The possible consequences of ignoring a warning are shown here.
If you ignore the warning notice, the "WARNING" signal word indicates that a lethal or severe
injury may occur.
➤ The measures required to protect yourself from danger are shown here.
2. Always read and comply with warning instructions.
2.5.2 Potential damage warnings
Contrary to the warnings shown above, damage warnings do not indicate a potential personal in‐
jury.
Warning notices for damages are identified by their signal term.
Signal term Meaning Consequences of non-compliance
NOTE Warns of a potentially dangerous situation Damage to property is possible
Tab. 6 Danger levels and their definition (damage to property)
Example:
NOTICE
These show the kind of danger and its source.
Potential effects when ignoring the warning are indicated here.
➤ The protective measures against the damages are shown here.
➤ Carefully read and fully comply with warnings against damages.
