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 AT235
requires continued operation during
power mains interruptions, it is
recommended that the AT235 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.
