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

Interference may occur in the

with the following symbol:
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.
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
Hybresis Charging Station is used exceeds the applicable RF compliance level above, the Hybresis Charging
Station should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the Hybresis Charging Station.
