Electrostatic discharge
(ESD) IEC 61000-4-2
Floors should be wood, concrete
or ceramic tile. If the floor is
covered with synthetic material,
the relative humidity should be at
least 30%. If ESD interfere with
the operation of equipment,
counter measurements such as
wrist strap, grounding shall be
considered.

a typical commercial or hospital
environment. If the user of the
TL-100D requires continued
operation during power
interruptions, it is recommended
that the TL-100D be powered
