RF emissions
CISPR 11
Group 1
REAL Immersive System uses RF energy only for
its internal function. Therefore, its RF emissions are
very low and are not likely to cause any interfer-
ence in nearby electronic equipment.

a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radi-
os, 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 Immersive System is used exceeds the applicable RF compliance
level above, REAL Immersive System should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating REAL Immersive System.

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 Immersive System
REAL Immersive System is intended for use in an electromagnetic environment in which radiated RF disturbances are con-
trolled. The customer or the user of REAL Immersive System can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and REAL Immersive System
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.
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 reflec-
tion from structures, objects and people.
