The ergoselect ergometer is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of the ergoselect ergometer can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the ergoselect ergometer as recommended below, according to the maximum output
power of the communications equipment.

[m]
150 kHz to 80 MHz
d = 1.2 √P
80 MHz to 800 MHz
d = 1.2 √P
800 MHz to 2.5 GHz
d = 2.3 √P
0.01 0.12 0.12 0.23
0.1 0.37 0.37 0.74
1 1.17 1.17 2.33
10 3.7 3.7 7.37
100 11.7 11.7 23.3
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using
the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according
to the transmitter manufacturer.
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 aected by absorption and reection from structures,
objects, and people.
