1.7 Precautionary Measures
WARNING!
Eliminate safety risks!
Disconnect the CARDIOHELP from the external power supply and remove the batteries before carrying
out maintenance.
WARNING!
Electrical components are live!
While the CARDIOHELP is connected to the internal or external power supply, the electrical components
are live.
During troubleshooting or when making settings on the open device, the service technician must take
particular care.
WARNING!
Maintenance work should not be carried out during an intended use.
Maintenance work should only be carried out if there is no patient on the CARDIOHELP.
WARNING!
Eliminate safety risks!
Carry out an inspection after every service or repair measure and after opening the device. This will
eliminate possible injury risks.
CAUTION!
Electrostatic discharge can cause damage to electronic components.
To prevent damage to ESD-sensitive components, an ESD-protected environment must be set up.
To prevent damage and malfunctions, defined handling instructions must be observed when handling
ESD-sensitive components.
The ESD-protection equipment must always be used appropriately.
In addition to the important information provided here and in the relevant accompanying documents (e.g.,
Instructions for Use) the important local and national regulations must always be taken into consideration.
