Recommended separation distances between
portable and mobile RF communications equipment and the model smartho-D2
The Model smartho-D2 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Model smartho-D2 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the
Model smartho-D2 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 metres (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.
Recommended separation distances between RF wireless communications equipment
The device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the device can help prevent electromagnetic interference by maintaining a minimum
distance between RF wireless communications equipment and the device as recommended below, according to the
maximum output power of the communications equipment.

RF wireless communications
equipment should be used no
closer to any part of the device,
including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
Where P is the maximum output
power rating of the ransmitter in
watts (W) according to the
transmitter manufacturer and d is
the recommended separation
distance in meters (m). Field
strengths from fixed RF transmitter,
as determined by an
electromagnetic site survey, should
be less than the compliance level in
each frequency range. Interference
may occur in the vicinity of
equipment marked with the
