The field intensities set by the fixed transmitters, such as radio base stations, telephones (mobile
phone, wireless) land mobile radio, amateur radio, AM and FM radio transmissions and TV
transmissions can not be predicted with accuracy. Due to the RF fixed transmitters is recommended to
install an electromagnetic inspection at the local in order to evaluate the electromagnetic environment.
If at the place where the equipment is be using the field intensity level exceeds the conformity level for
the RF above, is recommended to observe if the operations are normal. Whether abnormal operations
are observed, additional procedures shall be necessary such as reorientation or replace the
equipment.
Whether above the frequency range of 150kHz to 80 MHz is recommended a field intensity below than 3
V/m.
The is made to be used in the electromagnetic environments specified below. The
client or the user of the must be sure that it is used in such environment.

It is advisable that portable and
mobile RF communication equipment
is not used near any part of the
equipment, including cables, with a
separation distance less than the one
recommended, calculated from the
equation applicable to the frequency
of the transmitter.
Recommended separation distance:
d=1,2 P√
d=1,2 P80 MHz thru 800MHz
d=2,3 P 800 MHz thru 2,5MHz
Where Pis the nominal maximum
power of output of the transmitter in
watts (W), as per the manufacturer of
thetransmitter, anddisthe
recommended separation distance in
meters (m).
It is advisable that the fiel intensity
from theRF, transmitteras
determined by means of electric
inspection on-site, ªis less than the
level of compliance in each frequancy
range .
There maybe interference near the

NOTE 1 At 80MHz and 800MHz, the highest frequency range applies.
NOTE 2 These directives may not be applicable in every situation. The electromagnetic
transmission is affected by the absorption and reflection of structures, objects and people.
