Crucial Features Of Performance; Minimum Distances - KERN and SOHN MTA 400K-1M Notice D'utilisation

8.3.1 Crucial features of performance

Note:
The personal weighing scales MTA-M do 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.

8.4 Minimum distances

Recommended safety distances between portable and mobile HF
telecommunication devices and the personal weighing scales MTA-M
The personal weighing scales MTA-M are designed for use in an electromagnetic
environment in which HF disturbance variables are controlled. The customer or user of the
personal weighing scales MTA-M can help avoiding electromagnetic disturbances by keeping
the minimum distance between portable and mobile HF telecommunication devices
(transmitters) and the personal weighing scales MTA-M - 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.
