Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
The ergoselect 1 ergometer is intended for use in the electromagnetic environment specified below. It is the responsibility of the
customer or user to ensure that the ergoselect 1 ergometer is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer
to any part of the ergoselect 1 ergometer,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance:
d = 1.2 √P
d = 1.2 √P for 80 MHz to 800 MHz
d = 2.3 √P for 800 MHz to 2.5 GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufac‑
turer and d is the recommended separa‑
tion distance in meters (m).
Field strengths from fixed RF transmit‑
ters, as determined by an electromag‑
netic 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 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
ergoselect 1 ergometer is used exceeds the applicable RF compliance level above, the ergoselect 1 ergometer should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re‑orienting or relocating the ergoselect 1
ergometer.
b) Over the frequency range from 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
