kPa (20 PSI). Because of additional optional
equipment, it may be necessary to increase
the pressure. Slowly increase the air pressure
by adjusting the air regulator on the base
chassis until the chair begins to "bounce".
This is an indication that the air pillow is
over pressurized and can not seal to the oor.
Slowly decrease the pressure until the chair
stops bouncing.
4. Actuate the air regulator toggle switch at the
rear of the chair on the base cantilever section
cover.
5. Check for proper air glide operation.

The NuSimplicity Chair uses RF energy only for its
internal function. Therefore, its RF emissions are very
low and are not likely to cause any interference in
nearby electronic equipment.
The NuSimplicity Chair is suitable for use in all
establishments, other than domestic establishments
and those directly connected to the public low-voltage
power supply network that supplies buildings used for
domestic purposes.

Recommended separation distance between
Portable and mobile RF communications equipment and the model @ 3Vrms
The NuSimplicity Chair is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the CMU can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the NuSimplicity C
hair as recommended below,
according to the maximum output power of the communications equipment.
Separation distance according to frequency of transmitter m
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 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 1:These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.

by an electromagnetic site survey, should be less than
the compliance level in each frequency range.

NOTE 1 At 80 MHz and 800 MHz, 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.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, 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 NuSimplicity Chair is
used exceeds the applicable RF compliance level above, the NuSimplicity Chair should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the NuSimplicity Chair.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
