Electromagnetic environment - guidance
The Model CP770DW uses RF energy only for its
internal function. Therefore, its RF emissions are very
low and are not likely to cause interference in nearby
electronic equipment.
The Model CP770DW is suitable for use in all
establishments, including domestic establishments and
those directly connected to public low-voltage power
supply network that supplies buildings used for
domestic purpose.
Electromagnetic 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.
