Guidance and manufacture’s declaration – electromagnetic immunity
The CP-ONE PLUS is intended for use in the electromagnetic environment specified below. The customer or the
user of the CP-ONE PLUS should assure that it is used in such an environment.

guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the CP-ONE PLUS, including cables, than the
recommended separation distance calculated
from the equation applications to the Frequency
of the transmitter.

transmitter manufacturer and
d is the
recommended separation distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be less than the compliance level in each
frequency range.
b
Interference may occur in the vicinity of equipment marked with the following
symbol:
NOTE 1 At 80 MHz and 800MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by adsorption
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 CP-ONE PLUS is
used exceeds the applicable RF compliance level above, the CP-ONE PLUS should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the CP-ONE PLUS.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Essential performance (purpose of IMMUNITY testing)
Unless operated by the switches for chair control, the chair section of the CP-ONE PLUS does not make
any movements, except for sounding a buzzer and switching on/off the indicator.
