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 institution environment. If the
user of the SEM Scanner 200 charging system
requires continued operation during power
mains interrupts, it is recommended that the
SEM Scanner 200 system be powered from an
uninterruptible power supply or a battery.

Portable and mobile RF communications
equipment should be used no closer to any part
of the SEM Scanner 200 system, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of the transmitter.
