Occlusion alarm
* Data as evaluated by the test methods of IEC 60601-2-24.
Note: the bolus volume after occlusion release (2 ml) is not considered as a hazardous situation when
the device is used for its intended use.
Warning
The internal battery should be changed every 2 years. In case of
a prolonged storage period (more than 4 months), it is
recommended that the battery is removed.
Battery replacement must be performed by qualified and trained
technical personnel in compliance with the technical manual and
procedures.
