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

(>95% dip in UT)
for 5 sec Mains power
quality should be that of

If the user of the AD226
requires continued
operation during power
mains interruptions, it is
recommended that the
AD226 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.
