Chapter A - GENERAL & TECHNICAL DATA
Guidance and manufacturer's declaration - electromagnetic immunity
Planmeca Compact i dental unit is intended for use in the electromagnetic environment specified below.
The customer or the user of Planmeca Compact i dental unit should assure that it is used in such an
environment.
Immunity test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
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 Planmeca Compact i dental unit is used exceeds the
applicable RF compliance level above, Planmeca Compact i dental unit should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating Planmeca Compact i dental unit.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

level
Portable and mobile RF communications
equipment should be used no closer to any
part of the Planmeca Compact i dental unit,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of the
transmitter.
