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 2 Face / Face Evolution (Model: 2
Face / Face Evolution) is used exceeds the applicable RF
compliance level above, the 2 Face / Face Evolution
(Model: 2 Face / Face Evolution) should be observed to
verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as
re-orienting or relocating the 2 Face / Face Evolution
(Model: 2 Face / Face Evolution).
b. Over the frequency range 150 kHz to 80 MHz, field
strengths should be less than 3 V/m.
Recommended separation distances between portable
and mobile RF communications equipment and the
Model 2 Face
The 2 Face / Face Evolution (Model: 2 Face / Face
Evolution) is intended for use in an electromagnetic
environment in which radiated RF disturbances are control
RGB. The customer or the user of the 2 Face / Face
Evolution (Model: 2 Face / Face Evolution) can help prevent
electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications
equipment (transmitters) and the 2 Face / Face Evolution
(Model: 2 Face / Face Evolution) 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 meters
(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 transmitter manufacturer.
NOTE1 At 80 MHz and 800 MHz, the separation distance
for the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
