Notes on electromagnetic compatibility
(EMC)
Where EMC is concerned, medical electrical units are subject to special safety mea-
sures and must be installed and commissioned according to the EMC notes stated
herein.
Use of non-approved EMC-relevant accessories
This can result in the increased emission of electromagnetic interfer-
ence or reduce the electromagnetic immunity of the unit.
Risk of injury to the patient.
Units may fail or not function properly.
Only use cable that is specified in the table "EMC-relevant acces-
sories", see chapter "Notes on electromagnetic compatibility
(EMC)".
If you are using accessories from other manufacturers, check
whether the Erbe unit is interfering with other units or being af-
fected by interference itself. You cannot use the unit if there is any
interference.
Stacked units
If you place the unit next to or stack it with other units, the units may
affect each other.
Risk of injury to the patient.
Units may fail or not function properly.
The unit may only be placed next to or stacked with VIO-series
units.
If it is necessary to operate the unit near or stacked together with
non-VIO-series units keep as much distance as possible between
the units. Check whether the units are affecting each other: Are
the units behaving unusually? Are faults occurring?
Interference with the unit from portable and mobile HF telecom-
munications units (e.g. mobile phones, WLAN units)
Electromagnetic waves emitted by portable and mobile HF telecom-
munications units may affect the unit.
Risk of injury to the patient.
The unit may fail or not perform properly.
When using portable and mobile HF telecommunications units, in-
cluding their accessories, there must be a distance of at least
30 cm between them and the unit and its cords.
