Guidance and manufacturer’s declaration - electromagnetic immunity
The ENDO-MATE DT2 is intended for use in the electromagnetic environment specified below� The customer or the
user of the ENDO-MATE DT2 should assure that it is used in such an environment�
Immunity test IEC60601 test level Compliance level Electromagnetic environment -
guidance
Conducted RF
IEC61000-4-6 3Vrms
150 kHz to 80MHz 3 Vrms Portable and mobile RF communications
equipment should be used no closer to
any part of the ENDO-MATE DT2,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter�
Radiated RF
IEC61000-4-3 3V/m
80MHz to 2�5 GHz 3 V/m Recommended separation distance
d = 1�2 √ P
d = 1�2 √ P 80 MHz to 800 MHz
d = 2�3 √ P 800 MHz to 2�5 GHz
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 metres (m)�
Field strengths from fixed RF transmitters
as determined by an electromagnetic site
survey, should be less than the
compliance level in each frequency
range�
Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE 1 At 80MHz and 800MHz, 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
mobiles 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 ENDO-MATE DT2 is
used exceeds the applicable RF compliance level above, the ENDO-MATE DT2 should be observed to verity
normal operation� If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the ENDO-MATE DT2�
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m�
