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 radios, amateur 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 BEMER Horse-Set products
is used exceeds the applicable RF compliance level above, the BEMER Horse-Set products should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the BEMER Horse-Set products.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Use of the BEMER Horse-Set devices near HF surgical equipment, trains, boats, planes, short wave therapy
equipment or inside the RF shielded room of MRI systems may cause degradation or loss of device function-
ality due to EM disturbances.
Compliance Electromagnetic environment – guidance
level
3 A/m Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical
commercial or hospital environment.
Compliance Recommended separation distance c
level
Portable and mobile RF communications equipment
should be used no closer to any part of the BEMER Horse-
Set products, including cables, than the recommended
separation distance calculated from 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 and d is the recommended separation
distance in metres (m).
Field strengths from fixed RF transmitters, as determined
by an electromagnetic site survey:
should be less than the compliance level in each
frequency range.
