The ec5000 ergometer is intended for use in the electromagnetic environment specifi ed below. It is the responsibility
of the customer or user to ensure that the ec5000 ergometer is used in such an environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the ec5000
ergometer, including cables, than the recommend-
ed separation distance calculated from the equa-
tion 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 of the transmit-
ter in watts (W) according to the transmitter
manufacturer and d is the recommended separa-
tion distance in meters (m).
Field strengths from fi xed 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 aff ected by absorption and refl ection from
structures, objects, and people.
a) Field strengths from fi xed 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 fi xed RF transmit-
ters, an electromagnetic site survey should be considered. If the measured fi eld strength in the location in which the ec5000 ergometer is used
exceeds the applicable RF compliance level above, the ec5000 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 ec5000 ergometer.
b) Over the frequency range from 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.
