Guidance and manufacturer's declaration – electromagnetic immunity
X-MIND unity is intended to be used in the electromagnetic environment specied below. The customer or X-MIND unity operator must
ensure that the device is used in this type of environment.
Immunity test IEC 60601 test level Compliance level Electromagnetic environment guidance
Portable and mobile RF communication equipment must be
used no any closer to any part of the X-MIND unity, including
cables than the recommended separation distance, calcula-
ted according to the equation corresponding to the frequen-
cy of the transmitter
Recommended separation distance
Conducted RF
IEC 61000-4-6
3 Vrms
150 kHz à 80 MHz

Radiated RF

d= 2,3 √P 800 MHz à 2,5 GHz
where P is the maximum output power rating of the trans-
mitter in watts (W) according to the transmitter manufacturer
and “d” is the recommended separation distance in metres
(m).
Field strength from xed RF transmitters as determined by an
electromagnetic site surveya must be below the compliance
level corresponding to each frequency range.b
Interference can occur in the proximity of equipment marked
with the following symbol:
Notes:
• At 80 MHz and 800 MHz the higher frequency range applies.
• These guidelines may not apply in every situation. Electromagnetic propagation is affected by absorption and reection from struc-
tures, objects and people.
a
Field strength from xed RF transmitters, such as base stations for radio (cellular/wireless) telephones and land mobile radios, ama-
teur radio, AM and FM radio and TV broadcast cannot be predicted with accuracy on a theoretical basis. To assess the electromagnetic
environment created by xed RF transmitters, an electromagnetic site survey should be considered. If the measured eld strength in the
place where the equipment is used exceeds the corresponding RF compliance level (see above), it is important to ensure regular equip-
ment operation. In the event of abnormal operation, additional measures may be required, such as redirecting or relocating X-MIND
unity.
b
Over the frequency range between 150 kHz and 80 MHz, the eld strength must be below 10 V/m.
