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

80 MHz to 800 MHz

d = 2,3√p

800 MHz to 2.5 GHz

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.

Interference may occur in the vicinity of

equipment marked with the following

symbol.
