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

Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the
TENS+EMS SUPER DUO
requires continued operation
during power mains interruptions,
it is recommended that the
TENS+EMS SUPER DUO be powered
from an uninterruptible power
supply or a battery.
The TENS+EMS SUPER DUO power
frequency magnetic fields should be
at levels characteristic of a
typical location in a typical
commercial or hospital environment.
