This equipment needs special precautions regarding EMC and needs to be installed and put
into service according to the EMC information listed below
Guidance and manufacturer’s declaration – Electromagnetic immunity
The MYTHIC 18 is intended for use in the electromagnetic environment specified below. The customer or
the user of the MYTHIC 18 should assure that it is used in such environment.
Immunity test IEC 60601 test level Compliance
level
Electromagnetic environment - guidance
Portable and mobile RF communications equipment should
be used no closer to any part of the MYTHIC 18,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.

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 meters (m).
Field strenghts from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be
less than the compliance level in each frequency range.
b
Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE 1 At 80Mhz and 800MHz, the higher frequency range apllies.
NOTE 2 Theses guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
a
Field strenghts from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM an 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 considered. If the measured field
strenght in the location in which the MYTHIC 18 is used exceeds the applicable RF compliance level above, the MYTHIC 18 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting
or relocating the MYTHIC 18.
b
Over the frequency range 150KHz to 80MHz, field strenghts should be less than 3V/m.
