COMPACT PIEZO LED
Guidance and manufacturer's declaration - Electromagnetic immunity
The compact piezo LED is intended for use in the electromagnetic environment specified
below.
The customer or user of the compact piezo LED should ensure that it is used in such an
environment.

N.B.:
(1) at 80 MHz and 800 MHz, the higher frequency range applies.
(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 any reasonable 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
compact piezo LED is used exceeds the applicable RF compliance level given above, the compact piezo LED should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the
b Over the frequency range from 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Portable and mobile RF
communications equipment should
be used no closer to any part of the
device including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
d = 1,2 √P
d = 1,2 √P from 80 MHz to 800 MHz
d = 2,3 √P from 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 metres (m).
