for 5 sec Mains power quality
should be that of a typical
commercial or residential
environment. If the user of the
Affinity requires continued
operation during power mains
interruptions, it is
recommended that the Affinity
be powered from an
uninterruptable power supply
or its battery.
Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical
commercial or residential
environment.
