Electromagnetic environment
— guidance
Floors should be wood, concrete
or ceramic tile. If floors are covered
with synthetic material, the relative
humidity should be at least 30%.
Mains power quality should be that
of a typical commercial or hospital
environment.
Mains power quality should be that
of a typical commercial or hospital
environment.
Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the
ET-9090/ET-1313/ET-7070 requires
continued operation
during power mains interruptions, it
is recommended that the
ET-9090/ET-1313/ET-7070 be pow-
ered from an uninterruptible power
supply or a battery.
Not applicable.
