Electromagnetic Immunity
Extraoral Suction System is designed for electromagnetic environment described below. Be sure to apply.

The isolation distance between
portable and mobile RF
communications devices and any
part of the Extraoral Dentistry
Suction System, including cables,
should not be less than
recommended isolation distance.
The recommended isolation distance
is calculated by a formula
corresponding to the frequency
ofthe transmitter. Recommended

The field strength of the fixed RF
transmitter is determined by
surveying the electromagnetic field
a, and in each frequency range
dshould be lower than the
compliance level. Interference may
occur near the equipment marked
with the following symbol.
Note 1: At 80MHz and 800MHz frequencies, apply higher frequency band formula.Note 2: These guidelines may
not be suitable for all situations. Electromagnetic propagation is affected by absorption and reflection from
buildings, objects and human bodies.
The field strengths of fixed transmitters, such as: base stations for wireless (cellular/cordless) phones and
terrestrial mobile radios, amateur radios, AM and FM radio broadcasts, and television broadcasts, cannot be
accurately predicted theoretically. To assess the electromagnetic environment of fixed RF transmitters, surveys of
electromagnetic sites should be considered. If the measured field strength of the Extraoral Suction System is higher
than the applicable RF compliance level above, the Extraoral Suction System should be observed to verify that it
can operate normally. If abnormal performance is observed, supplementary measures may be necessary, such as
reorienting or repositioning the Extraoral Suction System.In the entire frequency range of 150kHz to 80MHz, the
field strength should be lower than 3V/ m.
