IEC STANDARD 60601-1-2:2014, 4th Edition
This device is approved for use in a specifi c electromagnetic environment. The customer or user of the
device must ensure that it is used in an electromagnetic environment in accordance with the description
given below.
Emission Measurement Agreement Guidelines Regarding the Electromagnetic
Environment
RF-emission according to
CISPR 11 Group 1 This device uses RF-energy for internal functions only. RF-
emissions are therefore very low, and it is unlikely that other
nearby electronic equipment will be disturbed.
RF-emission according to
CISPR 11 Class B The device is suitable for use in all environments, including
residential areas, and approved for direct connection to the
public low-voltage network for residential areas.
Harmonics according to
IEC 61000-3-2 Class A

The quality of the mains power supply should meet
the requirements for a normal commercial or clini-
cal environment. If the user of the product requires
continuous operation even with interruptions of the
power supply, the product should be connected to
an uninterruptible power supply.
