Technical
characteristics
EcoStar
Essential performance requirements for electromagnetic
compatibility
The EcoStar device generates an over pressure and regulates it to make the patient sleep properly.
The device retains its settings and the value of the delivered pressure remains that of the set
pr /-0.5cm H
2
O.
If the Essential performance is lost or degraded, the delivered pressure could be different of the set
pressure. It is widely recognized that a patient will be resume breathing after the 5 seconds
interruption or that the patient will reset the device (without experiencing a hazard) when he notices
the display has stalled.
Electromagnetic emissions
The EcoStar device is designed for use in the electromagnetic environment specified below. The
customer or the user of an EcoStar device should ensure that it is used in such an environment.
Emission test

Recommended electro-magnetic environment
RF emissions
CISPR 11
Group 1
The EcoStar device uses RF energy only for its internal
operation. Therefore its RF emissions are very low and
cannot be assumed to interfere with nearby electronic
equipment.
RF emissions
CISPR 11
Class B
The EcoStar device is suitable for use in all
establishments including residential establishments and
those directly connected to the public low-voltage power
supply network which supplies residential buildings.
