INSTRUCTIONS FOR USE
17.3 Electromagnetic immunity
The dental unit is intended for use in the electromagnetic environment meeting the requirements in Table 17.3.
The customer or the user must assure that the dental unit is used in such an environment.
Table 17.3
Immunity test
Immunity to conducted
disturbances, induced by
radio-frequency fields
according to
EN 61000-4-6
Immunity to radiated, radio-
frequency electromagnetic
field according to
EN 61000-4-3
Note 1
For frequency of 80 MHz the frequency range of 80 MHz to 800 MHz applies
and for the frequency of 800 MHz the frequency range of 800 MHz to 2,5 GHz applies.
Note2
These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones, mobile radios,
amateur radio, AM and FM radio and TV broadcast and the like cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to the fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the dental unit is used exceeds the applicable RF
compliance level above, its normal operation must be verified. If abnormal performance is observed, the dental unit
must be relocated.
Over the frequency range of 150 KHz to 80 MHz, field strengths should be less than 3 V/m.

Compliance Electromagnetic environment
Portable and mobile RF communications
equipment should be used no closer than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended minimum distances:

Field strengths from fixed RF transmitters
should be less than the compliance level in
each frequency range.
