REAL i-Series is intended for use in the electromagnetic environment specified below. The customer or the REAL i-Series
should assure that it is used in such an environment.
Emissions Test Compliance
RF emissions
CISPR 11 Group 1
REAL i-Series uses RF energy only for its internal
function. Therefore, its RF emissions are very low
and are not likely to cause any interference in
nearby electronic equipment.

REAL i-Series is suitable for use in a residential
environment, institutional environment or any
facility that may facilitate rehabilitation.

Portable and mobile RF communications
equipment should be used no closer to
any part of REAL i-Series, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d = 1.2√P
d = 1.2√P 80 MHz to 800 MHz
d = 2.3√P 800 MHz to 2.7 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,ashould be less than the compliance
level in each frequency range.b
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 reflec-
tion from structures, objects, and people.
aField 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 REAL i-Series is used exceeds the appli-
cable RF compliance level above, REAL i-Series should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating REAL i-Series.
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 REAL i-Series
REAL i-Series is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of REAL i-Series can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and REAL i-Series as recommended below,
according to the maximum output power of the communications equipment.

FFor 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.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.
