Guidance and manufacturer’s declaration - electromagnetic immunity
The
Skin IQ
MCM is intended for use in an electromagnetic environment specified below. The customer or user of the
Skin IQ
MCM should assure that it is used in such an environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the
Skin IQ
MCM, including cables, than the
recommended separation distance calculated from
the equation application to the frequency of the
transmitter.

Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey (see
note a) should be less than the compliance level in
each frequency range (see note b).
Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE 1, At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2, These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
a) Field strengths from fixed 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 fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the
Skin IQ
MCM is used exceeds the applicable RF
compliance level above, the
Skin IQ
MCM should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the
Skin IQ
MCM.
b) Over the frequency range 150kHz, field strengths should be less than [V1] V/m.
