6.3.1 Crucial features of performance

Note:

The personal scale MPD-M does not have any crucial features of
performance as per IEC 60601-1. The system may be subject to
interference by other devices even if these devices conform to current
emission requirements as per CISPR.

6.4 Minimum distances

Recommended safety distances between portable and mobile HF
telecommunication devices and the medical device

The medical device is designed for use in an electromagnetic environment in which HF disturbance
variables are controlled. The customer or user of the medical electrical device can help avoiding
electromagnetic disturbances by keeping the minimum distance between portable and mobile HF
telecommunication devices (transmitters) and the medical device

– depending on the output

performance of the communication device, as stated below.

For transmitters with a maximum rated capacity not stated in the table above you can calculate the
recommended safety distance in metres (m) yourself by using the equation belonging to each column,
whereby P equals the maximum rated capacity of the transmitter in Watt (W) as per details provided
by the transmitter manufacturer.

NOTE 1 Higher frequency range applies to 80 MHz and 800 MHz.
NOTE 2 These guidelines may not be applicable in all cases.

The spread of electromagnetic variables is influenced by absorption and reflections in

buildings, objects and humans.
