Test Level

Level

Environment - Guidance

Portable and mobile RF

communications equipment

should be used no closer to

any part of the model REF

130-002, including cables,

than the recommended

separation distance

calculated from the equation

applicable to the frequency

of the transmitter.

d = [ ]√P 80 MHz to

800 MHz

d = [ ] √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,

should be less

than the compliance level in

each frequency range.

Interference may occur in the

vicinity of equipment marked

with the following symbol:

3 Vrms

150kHz-80MHz

3 V/m

80MHz-2.5GHz

NOTE 1: U

is the a.c. mains voltage prior to application of the test level.

NOTE 2: At 80MHz and 800MHz, the higher frequency range applies.

NOTE 3: 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 model

130-001 is to be used exceeds the applicable RF compliance

level above, the model

130-001 should be observed to verify normal

operation. If abnormal performance is observed, additional measures may be

necessary, such as re-orienting or relocating the model

130-001.

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