Guidance and manufacture's declaration – electromagnetic immunity
The YPB-2100 is intended for use in the electromagnetic environment specified below. The customer or the user
of the YPB-2100 should assure that it is used in such an environment.
Immunity test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
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 YPB-2100 is used exceeds
the applicable RF compliance level above, the YPB-2100 should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
YPB-2100.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

e level
Portable
equipment should be used no closer to any part of
the YPB-2100, including cables, than the
recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.
Recommended separation distance
3 Vrms
3 V/m
Where P is the maximum output power rating of
the transmitter in watts (W) according to the
transmitter
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.
