Electromagnetic immunity, RF portable equipment

The Piezon Master 400 is intended for use in the electromagnetic environment specified below. The
customer or the user of the Piezon Master 400 should assure that it is used in such an environment.
Immunity test IEC 60601
test level
Portable and mobile RF communications equipment should be used no closer to any part of the
Piezon Master 400, including cables, than the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to
80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to
2.5 GHz
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,
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 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 Piezon Master 400 is used exceeds the applicable RF compliance
level above, the Piezon Master 400 should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating
the Piezon Master 400.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
