Guidance and manufacturer´s declaration – electromagnetic immunity
The Project E Beauty LED Light Therapy Mask is intended for use in the electromagnetic environment
speci ed below. The customer or the user of The Project E Beauty LED Light Therapy Mask should assure
that it is used in such an environment.

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic is a ected by absorption and
re ection from structures, objects and people.
a Field strengths from xed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to xed RF transmitters, an
electromagnetic site survey should be considered. If the measured eld strength in the location in which
the Project E Beauty LED Light Therapy Mask is used exceeds the applicable RF compliance level above,
The Project E Beauty LED Light Therapy Mask should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the
Project E Beauty LED Light Therapy Mask.
b Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 10V/m.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the Project E Beauty LED Light
Therapy Mask, including cables, than the
recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
