RF emissions
CISPR 11
Group 1
The Infant Phototherapy Equipment uses RF
energy only for its internal function. Therefore, its
RF emissions are very low and are not likely to
cause interference in nearby electronic
equipment.

Class B
The Infant Phototherapy Equipment is suitable for
use in all establishments, including domestic and
those directly connected to the public low-voltage
power supply network that supplies buildings
used for domestic purposes.

WARNING
The Infant Phototherapy Equipment should not be used adjacent to or stacked with other
equipment. If adjacent or stacked use is necessary, the Infant Phototherapy Equipment
should be observed to verify normal operation in the configuration in which it will be used.
Portable RF communications equipment (including peripherals such as antenna cables and
external antennas) should be used no closer than 30 cm (12 inches) to any part of the device,
including cables specified by the manufacturer. Otherwise, degradation of the performance
of this equipment could result.
Use of adapter other than those specified or provided by the manufacturer of this
equipment could result in increased electromagnetic emissions or decreased
electromagnetic immunity of this equipment and result in improper operation.
9.2 Recommended separation distances between portable and mobile RF communications
equipment and the Infant Phototherapy Equipment
The Infant Phototherapy Equipment is intended for use in the electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the Infant
Phototherapy Equipment can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment and the Infant
Phototherapy Equipment as recommended below, according to the maximum output power of
the communications equipment.

For transmitters 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.
NOTE2) These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects, and people.
