6.3.1 Crucial features of performance
The baby scale MBA-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 baby scale MBA-M is designed for use in an electromagnetic environment in which HF
disturbance variables are controlled. The customer or user of the baby scale MBA-M 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.
