2.2. ELECTROMAGNETIC EMISSION
RF emission CISPR 11, Group 1, Class A
Harmonic Emissions IEC 61000-3-2, Class A
Voltage changes/fluctuations and flickers IEC 61000-3-3
NOTE:
The EMISSIONS specifications for this equipment make it suitable for use in industrial areas and hospitals (CISPR 11 Class A).
If the chair is used in a residential environment (which normally requires CISPR 11 Class B), this equipment might not provide
adequate protection for radiofrequency communication services. The user might have to take necessary precautions,
such as moving or adjusting the equipment.
