10.3 - Electromagnetic immunity / mobile radiofrequency equipment
The MINI L.E.D. is intended for use in the electromagnetic environment specified in the table below.
The user and/or installer must ensure that the device is used in such an electromagnetic environment.
Note 1
: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2
: These specifications may not be applicable in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and persons.
(a)
: The electromagnetic field strengths of fixed radiofrequency emitters, such as base stations for mobile telephones
(cellular/cordless), mobile radios, amateur radios, AM/FM radio broadcasts and TV broadcasts cannot be
determined exactly by theory. To assess the electromagnetic environment due to fixed radiofrequency emitters,
an electromagnetic environment measurement must be made. If the measured radiofrequency field strength in
the immediate environment where the product is used exceeds the compliance level specified above, the
performance of the product must be tested to verify whether it conforms to the specifications. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the product.
(b)
: In the 150 kHz to 80 MHz frequency range, the electromagnetic field strengths must be less than 3 V/m.
10.4 - Recommended separation distances
The M
INI L.E.D. is intended for use in an electromagnetic environment in which radiated radiofrequency disturbances
are controlled. The M
INI L.E.D. user and/or installer can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile radiofrequency communications equipment (emitters) and the M
INI
L.E.D., according to the maximum output power of the equipment, as recommended in the table below.
Immunity test IEC 60601 test level aCompliance level Electromagnetic environment - guidance
Portable and mobile radiofrequency communications devices must not be used near the MINI L.E.D. (including its cables) at a distance less than that
recommended and calculated according to the frequency and power of the emitter.

Where P is the maximum power rating of the emitter in watts (W)

recommended minimum separation distance in meters (m).
The electromagnetic field strengths of fixed radiofrequency emitters, as determined by an electromagnetic environment measurement (a), must be
less than the compliance level in each frequency range (b).

For emitters rated at max. power not listed above, the recommended separation distance d in meters (m) can be estimated using
the equation applicable to the frequency of the emitter, where P is the max. power rating of the emitter in watts (W) according
the manufacturer.
