Guidance and manufacturer’s declaration – electromagnetic immunity
The Wattbike is intended for use in the electromagnetic environment specified below.
The customer or the user of the Wattbike should assure that it is used in such an environment.
Immunity test
IEC 60601 test level
Compliance level
Electromagnetic environment -
guidance
Portable and mobile RF
communications equipment
should be used no closer to any
part of the Wattbike , including
cables, than the recommended
separation distance calculated
from the equation applicable to
the frequency of the transmitter:
Recommended separation
distance
Conducted RF
IEC 61000-4-6
3 Veff
150 kHz to 80 MHz
3 V
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to 2,5 GHz
3 V/m
80 MHz to 800 MHz
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).
b
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,
a
should be less than the compliance level in each
frequency range.
b
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 Wattbike is used exceeds the applicable RF compliance level above, the Wattbike
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocation the Wattbike.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
