Guidance and manufacturer's declaration — electromagnetic immunity
The Sera TM is intended for use in the electromagnetic environment specified below. The customer or the
user of the Sera should assure that it is used in such an environment,

NOTE1 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 Sera
observed to verify normal operation, If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the Sera
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
