Table 204 - Guidance and manufacturer's declaration - electromagnetic immunity
PRISMALIX surgical lights are intended for use in the electromagnetic environment specified below. PRISMALIX customers or
users should ensure that they are used in such an environment.
Immunity test

80 MHz to 2.5 GHz
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.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
a
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 PRISMALIX is used exceeds the applicable RF compliance level above, the
PRISMALIX should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the PRISMALIX.
Over the frequency range 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 PRISMALIX, including
cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the
transmitter.
