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

Interference may occur in the vicinity of

Notes:
(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 reflec
-
tion 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 Silverlight is used exceeds the
applicable RF compliance level above, the Silverlight should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the Silverlight.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
