Floors should be wood, concrete
or ceramic tile. If floor are
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.

of the TL-100Drequires continued
operation during power mains
interruptions, it is recommended
that the TL-100Dbe powered
from an uninterruptible power
supply or a battery.
