TECHNICAL SPECIFICATIONS
Manufacturer's guidelines and declaration - Electromagnetic immunity
New Versa Chair is intended for use in the electromagnetic environments specified below. The
customer or the user of the New Versa Chair should ensure that it is used in such an environment.

It is recommended that portable and
mobile RF communication equipment
should not be used near any part of the
New Versa Chair including cables, with less
than the recommended separation
distance, calculated from the equation
applicable to the transmitter frequency.
Recommended separation distance:
d = 1.2√P
d = 1.2√P 80 MHz to 800MHz
d = 2.3√P 800 MHz to 2.5MHz
Where P is the maximum nominal output
power of the transmitter, and d is the
recommended separation distance in
meters (m). It is recommended that the
field strength from the RF transmitter, as
determined through on-site
electromagnetic inspection, be less than
the level of compliance in each frequency
range
b
.
Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE 1 At 80MHz and 800MHz, the highest frequency range is applied.
NOTE 2 These guidelines may not be applicable in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a - Field strength from fixed transmitters, such as radio base stations for telephones (mobile or cordless phone)
and mobile ground radios, amateur radio, AM and FM radio broadcasts and TV broadcasts cannot be theoretically
predicted precisely. In order to assess the electromagnetic environment generated by fixed RF transmitters, an
electromagnetic field survey should be considered. If the field strength measured at the site where the New Versa
Chair will be used exceeds the applicable RF compliance level defined above, the New Versa Chair should be
observed to verify that it is functioning normally. If abnormal performance is detected, additional measures may be
necessary, such as reorienting or relocating the New Versa Chair.
b - Above the frequency range of 150kHz to 80 MHz, it is recommended that the field strength is less than 3 V/m.
