environment.
If the user of the S8 device
requires continued operation
during power mains
interruptions, it is
recommended that the S8
device be powered from an
uninterruptible power
source.
Power frequency

magnetic field
IEC 61000-4-8
3 A/m 3 A/m Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical
commercial or hospital
environment.
NOTE: Ut is the AC mains voltage prior to application of the test level.
