NOTE UT is the AC mains voltage prior to application of the test level.
Guidance and manufacturer's declaration – Electromagnetic immunity
The RADARMED is intended for use in the electromagnetic environment specified below. The
customer or the user of the RADARMED should assure that it is used in such an environment.
Immunity test IEC 60601 test level
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF
IEC 61000-4-3 3 V/ m
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.
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 RADARMED is used exceeds the applicable RF compliance level above, the
RADARMED should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the RADARMED.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF COMMUNICATIONS
EQUIPMENT AND THE RADARMED
The RADARMED is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the RADARMED can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the RADARMED as recommended below, according to the
maximum output power of the communications equipment.

Compliance Electromagnetic environment -
level Guidance
3 Vrms Portable and mobile RF
communications equipment should be
used no closer to any part of the
RADARMED, including cables, than the
3 V/m recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
�� = 1,17 √ ��
�� = 1,17 √ �� (80 ������ ���� 800 ������)
�� = 2,33 √ �� (800 ������ ���� 2,5 ������)
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).
