Environment-Guidance
Floors should be wood,
concrete or ceramic tile. If
floors are covered with
synthetic material, the relative
humidity should be greater
than 30%.
Mains power quality should be
that of a typical commercial or
residential environment.
Mains power quality should be
that of a typical commercial or
residential environment.
Mains power quality should be
that of a typical commercial or
residential environment. If the
user of the Sera requires
TM
continued operation during
power mains interruptions, it is
recommended that the Sera
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.
