Guidance and manufacturer’s declaration ± electromagnetic immunity

The FreeStyle is intended for use in the electromagnetic environment specified below. The customer or the user of the

FreeStyle should assure that it is used in such an electromagnetic environment.

Portable and mobile RF communications equipment

should be used no closer to any part of the FreeStyle

including cables, than the recommended separation

distance calculated from the equation applicable to the

frequency of the transmitter.

Recommended separation distance

D= 1.2 x √P

D= 1.2 x √P from 80MHz to 800MHz

D= 2.3 x √P from 800MHz to 2.5GHz

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 metres (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 symbol:

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.

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 FreeStyle is used

exceeds the applicable RF compliance level above, the FreeStyle should be observed to verify normal operation.

If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating

the FreeStyle.

b.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
