NOTE At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects, and people.
NOTE
: Field strength from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
a
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 concentrator is used exceeds the applicable RF compliance level above,
f
the concentrator should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the device.
: Over the frequency range 150 kHz to 80 MHz, the field strengths should be less than 3V/m.

Recommended Separation Distances between Portable and Mobile RF Communications
Equipment and This Device:
This concentrator is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The user of the concentrator can help prevent electromagnetic interference by maintaining a minimum distance
).
between portable and mobile RF communications equipment (transmitters) and this concentrator as recommended below,
according to the maximum output power of the communications equipment.
Rated Maximum Power
Output of Transmitter (W)
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.

Compliance Electromagnetic Environment - Guidance
Group 1 The concentrator uses RF energy only for its internal function. Therefore its
RF emissions are very low and not likely to cause any interference in nearby
equipment.
Class B The concentrator is suitable for use in all establishments, including domestic
establishments and those directly connected to the public low-voltage power
supply network that supplies buildings used for domestic purposes.
