Comment 1: The higher value applies to 80 MHz und 800 MHz.
Comment 2: These guidelines might not apply to all situations. The propagation of electro-
magnetic waves is affected by absorption and reflexes caused by buildings, objects and peo-
ple.
a
The field strength of a stationary transmitter e.g. standard cell phone stations (mo-
bile / cordless phones) and public mobile radio services, amateur stations, MW and UHF radio
and TV transmitters) cannot be precisely determined for theoretical reasons. It is recommend-
ed that an onsite test should be carried out in order to determine the electromagnetic environ-
ment caused by stationary HF transmitters. If the field strength of the massage device deter-
mined at the installation site exceeds the defined HF level listed above then the device must
be monitored with regard to its normal operation. If any abnormal characteristics are recorded
then it will be necessary to introduce additional measures, such as reorientation or converting
the device.
b
The field strength must be less than 3 V/m over the frequency ranges from 150 kHz
to 80 MHz.
