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 communications equipment
should be used no closer to any part of the ergoselect
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 rated output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as deter‑
mined 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 radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF trans‑
mitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the ergoselect 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.
