Electromagnetic immunity guidelines and statements - non life support equipment and systems
The equipment shall be used in the specified electromagnetic environment, and the customer or user
shall guarantee to use the equipment in the following specified electromagnetic environment

Portable and mobile RF communication
equipment must be used outside the specified
distance from any part of the equipment and
system (including cables). This isolation
distance is calculated according to the
appropriate equation of transmitter frequency
selection, and the calculation formula of your
isolation distance is:
d=1.2X
P
d=1.2X
P
80MHz to 800MHz
d=1.2X
P
800MHz to 2.5GHz
Where p is the rated output power of the
transmitter, in watts; D is the recommended
distance, in meters. The field strength of RF
transmitter measured by electromagnetic field
a must be less than the compliance level in
each frequency range B. Interference may
occur near equipment marked with the
following symbols;
Note 1: in 80MHz ~ 800MHz, the formula of higher frequency band is adopted.
Note 2: the above guidelines do not apply to all cases, because substances, structural objects and
people can absorb and reflect electromagnetic waves, which affect electromagnetic propagation.
The field strength of base station and ground mobile radio receiver, radio receiver, FM and am radio
broadcast and TV broadcast of a radio (cellular and wireless) mobile phone can not be accurately
estimated by pure theoretical method. In order to evaluate the electromagnetic environment
produced by the fixed RF transmitter, the method of electromagnetic field measurement should be
considered. If the field strength of the equipment exceeds the specified RF level, it is necessary to
observe whether the equipment can work normally. Once abnormal conditions are found, relevant
