Guidance & Declaration - Electromagnetic immunity
The models S6 LED are intended for use in the electromagnetic environment specified below. The customer or the user of the models S6 LED
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
models S6 LED, including cables, than the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance
d=[3,5/V1]×P1/2
d=1.2×P1/2 80 MHz to 800 MHz
d=2.3×P1/2 800 MHz to 2.5 GHz
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 meters (m). b
Field strengths from fixed RF a transmitters, as determined by an electromagnetic site survey, should
be less than the compliance level in each frequency range.
b
Interference may occur In the vicinity of equipment marked with the following symbol:
NOTE I At 80 MHz end 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 models S6 LED are used exceeds the applicable RF compliance level above,
the model S6 LED should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the models S6 LED.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
