Guidance and manufacturer's declaration – electromagnetic immunity for not life support equipment
The Product is intended for use in the electromagnetic environment specified below. The customer or the user of the Product should
assure that it is used in such an environment.
Immunity tests
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
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 Fixed 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 access the
electromagnetic environment due to fixed RF transmitters, and electromagnetic site survey should be considered. If the
measured field strength in the location in which the Product is used exceeds the applicable RF compliance level above, the
Product should b observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Product.
b over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
portable and mobile RF communications equipment and the not life support equipment
The Product is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or
the user of the Product can help prevent electromagnet interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the Product as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be
estimated using 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 higher frequency range applies.
Note 1: At 80 MHz and 800 MHz, the separation distance fort the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from

Portable and mobile RF communications
equipment should be used no closer to any part of
the Product, including cables, than the

the equation applicable to the frequency of the
transmitter.

Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
should be less than the compliance level in each
