Field strength from fixed RF transmitters, as determined in 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 following symbol:
Recommended separation distance between portable and mobile RF communication equipment and the device.
The SERENITY NEXT chair 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 portable and mobile RF communication equipment (transmitters) and the device as recommended below, according
to the maximum output power of the communication equipment.

For transmitters with a maximum output power not listed above, the recommended separation distance d in meters (m) can be determined using the equation applicable to the frequency of
the transmitter, where P is the maximum 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.
(2) These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
Conformity
Group 1 The product uses RF energy for its internal function only.
Therefore, its RF emissions are extremely low and not likely to cause interference with nearby electronic devices.
Class B It is possible to use the equipment in all buildings, including domestic use buildings, and those directly connected to
a public power supply network with a low voltage supplying buildings for domestic use, taking installation steps, and
guaranteeing an increased installation distance for potentially sensitive devices.
Class A It is possible to use the equipment in all buildings, including domestic buildings, and those directly connected to a
Conformity public power supply network with a low voltage supplying buildings for domestic use.

Portable and mobile RF communication equipment should be used no closer to any
part of the device, including cables, than the recommended separation distances calcu-
lated from the equation, applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1,2 P from 150kHz to 80MHz
d = 1,2 P from 80 MHz to 800 MHz
d = 2,3 P from 800 MHz to 2,5 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 me-
ters (m).
