Environment-Guidance
Floors should be wood, concrete
or ceramic tile. If f loors 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 f rom an uninterruptable
power supply or its battery.
Power f requency magnetic f ields
should be at levels characteristic
of a typical location in a typical
commercial or residential
environment.
