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 test
NOTE 1 At 80MHz and 800MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflected from structures, objects and people.
Field 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 assess the electromagnetic environment due to fixed RF transmitters, an
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 be 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 10 V/m.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer than
0,35m to any part of the product,
including
cables, than the recommended separation
distance calculated from the equation
applicable
to the frequency of the transmitter.
Recommended separation distance
d = 1,2√p
d = 2,3√p
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey, a should be less than the
compliance level in each frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following
