Guidance and manufacturer’s declaration - electromagnetic immunity
The Body Clock Stimplus Pro is intended for use in the electromagnetic
environment specified below. The user of the equipment or system
should ensure that it is used in such an environment
Immunity test IEC 60601 Compliance Electromagnetic environment guidance
Conducted RF 3 Vrms n/a Portable and mobile RFcommunications
IEC 61000-4-6 150kHz equipment should be used no closer
to 80MHz to any part of the Body Clock Stimplus Pro
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of the
transmitter.
Radiated RF 3V/m 3V/m
IEC 61000-4-3 80MHz to
2.5GHz
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 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 Body Clock Stimplus Pro
is used exceeds the applicable RF compliance level above, the Body Clock Stimplus Pro should
be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the Body Clock Stimplus Pro.
b. Over the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m.
