NOTE No deviations from the requirements of the standard are applied to EMC.
NOTE No other measures are known to maintain basic safety in terms of EMC.
NOTE Chairs equipped with a communication module work as standard IEEE 802.11 b/g/n (2 400 to 2 483,5 MHz, modulation
DSSS (IEEE 802.11 b ), OFDM (IEEE 802.11 g/n) 20MHz bandwidth EIRP = 0.34 W.
7 Use and Storage Conditions
DANGER!
Danger to life due to electric shock!
To ensure the chair’s class I protection against electric shocks:
► Ground the mains.
► Use exclusively Hospital Grade or Hospital Only receptacles for grounding.
Graciella Chair is designed for use in rooms for medical purposes. Electrical installations must therefore meet local norms laying
down the necessary conditions for electrical installations.
► Disconnect the chair from the mains in exceptional cases (i.e. lightnings, earthquake).
Graciella Chair is not suitable for indoor environments containing ammable gases (except oxygen cylinders).
