Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
The ergoselect 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 ergometer is used in such an environment.

Portable and mobile RF communica-
tions equipment should be used no
closer to any part of the ergoselect
ergometer, including cables, than
the recommended separation dis-
tance 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 manu-
facturer and d is the recommended
separation distance in meters (m).
Field strengths from fixed RF trans-
mitters, as determined by an electro-
magnetic 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 ergo select
ergometer is used exceeds the applicable RF compliance level above, the ergoselect 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 ergometer.
b) Over the frequency range from 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
