TECHNICAL SPECIFICATIONS
Guidelines and manufacturer's declaration - electromagnetic immunity
The Sonic Duo is made to be used in the electromagnetic environments specified below. The client
or the user of the
Sonic Duo
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 Sonic Duo , 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√P 80 MHz thru 800MHz
d = 2,3√P 800 MHz thru 2,5MHz
Where P is the nominal maximum power of
output of the transmitter in watts (W), as
per the manufacturer of the transmitter,
and d is the recommended separation
distance in meters (m).
It is advisable that the fiel intensity from
the RF, transmitter as determined by
means of electric inspection on-site
a
,is
less than the level of compliance in each
frequancy range
b
.
There may be interference near the
equipment
marked with the following symbol:
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.
a - 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 Sonic Duo 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 Sonic Duo.
b - Whether above the frequency range of 150kHz to 80 MHz is recommended a field intensity
below than 3 V/m.
