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.

Electrosurgical HF
Generator requires
continued operation during
power mains interruptions,
it is recommended that the
Estech COBRA™
Electrosurgical HF
Generator be powered from
an uninterruptible power
supply or battery.
