Derived HF disturbance
variables according to
IEC 61000-4-3
COMMENT 1: The higher frequency range applies at 80 MHz and 800 MHz.
COMMENT 2: These guidelines may not be applicable in all cases. The emission of electromagnetic variables is influenced by absorptions and
reflections from buildings, objects and persons.
a The field strengths of stationary transmitters such as, e.g. base stations of radio telephones and mobile radio communication devices, amateur
radio stations, AM and FM radio and TV stations, can not be exactly determined in advance. To determine the electromagnetic environment with
regard to stationary transmitters., an examination of the location should be considered. If the measured field strength at the location at which
the device is used exceeds the above-listed compliance level then the device should be monitored to prove correct function in accordance to the
instructions. If unusual performance is observed then additional measures may be required such as, e.g. different alignment or location of the
device.
b The field strength should be lower than 3 V/m for the frequency range 150 kHz ... 80 MHz.
Recommended protective clearance distances between portable and mobile HF telecommunications devices and the device
The device has been designed for use in an electromagnetic environment in which HF variables are controlled. The customer or user of the device
can help to prevent electromagnetic disturbances by keeping a minimum distance between portable and mobile HF telecommunication devices
(transmitters) and the device – dependent on the output power of the communication device, as listed below.

For transmitters whose maximum rated power is not indicated in the table above, the recommended protective clearance distance d in meters [m]
can be determined using the equation pertinent to the respective column, whereby P is the maximum rated power of the transmitter in Watt [W]
according to the specifications of the manufacturer of the transmitter.

Instructions on electromagnetic compatibility (EMC)
Electromagnetic environment – Guidelines
Portable and mobile radios should not be used at a closer
distance to the device, including the lines, than the recom-
mended protective clearance distance calculated using the
equation appropriate to the transmission frequency.
Recommended protective clearance:
d = 1.17 *
d = 0.18 *
d = 0.35 *
Where P is the rated power of the transmitter in Watt [W]
according to the specifications of the transmitter manufacturer
and d is the recommended protective clearance distance in
meters [m].
The field strength of radio transmitters should be lower than
the compliance level
