Electromagnetic immunity
Portable and mobile radio equipment should be used no closer to the BEMER SET CLASSIC/PRO and its power cables
than the recommended safety distance calculated from the equation applicable to the frequency transmitter.

Where P is the output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d
is the recommended safety distance in meters (m). The field strength from a stationary radio transmitter, according
to an onsite survey
a
is less than the compliance level
b
for all frequency ranges.
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.
The propagation of electromagnetic waves is affected by the absorption and reflection from structures, objects and people.
a)
Field strength from fixed transmitters such as base stations for radio (cellular/wireless) telephones and land mobile radios, amateur radio,
AM/FM radio stations and TV stations cannot be predicted theoretically with accuracy. To determine the electromagnetic environment
of a stationary transmitter, a site survey should be considered. If the measured field strength in the location in which the BEMER SET
CLASSIC/PRO is used exceeds the conformity level listed above, the BEMER SET CLASSIC/PRO should be monitored to verify normal
operation. If abnormal performance is observed, additional measures might be necessary, such as readjusting the BEMER SET CLASSIC/PRO
or changing to another location.
b)
The field strength is less than 3 V/m over the frequency range of 150 kHz to 80 MHz.
Use of BEMER Professional or BEMER Classic products near HF surgical equipment, trains, boats, planes, short wave therapy equip-
ment or inside the RF shielded room of MRI systems may cause degradation or loss of device functionality due to EM disturbances.
