Guidance and Manufacturer's declaration - Electromagnetic emissions
The dental unit is designed to operate in the specified electromagnetic environment. The customer or the user of the dental unit must
ensure its use in an electromagnetic environment with the following features:
Electromagnetic Environment
The dental unit uses RF energy only for its internal operation.
For this, the RF emissions are very low and do not interfere with the
electronic devices nearby.
The dental unit must be used only by adequately trained dentists and
paramedics. The dental unit may cause radio interferences or disturb
the operation of the nearby equipment. It may be necessary to adopt
countermeasures, such as re-orienting or moving the dental unit or
shielding the installation site.
Guidance and Manufacturer's declaration - Electromagnetic immunity
The dental unit is designed to operate in the specified electromagnetic environment. The customer or the user of the dental unit must
ensure its use in an electromagnetic environment with the following features:
Electromagnetic Environment
Electrostatic discharge
(ESD)
IEC 61000-4-2
± 8 kV contact
± 15 kV air
Floors must be made of wood, concrete or ceramic tiles.
If floors are covered with synthetic material, the relative
humidity should be at least 30%.
Proximity fields from RF
wireless
communications
IEC 61000-4-3
27 V/m at 385 MHz
28 V/m at 450, 810, 870, 930,
1720, 1845, 1970, 2450 MHz
9 V/m at 710, 745, 780, 5240,
5500, 5785 MHz
Portable and mobile RF communications equipment
should be used no closer to any part of the dental unit,
including cables, than the minimum distance
recommended in this section.
IEC 61000-4-4
fast/burst electric
transients
± 2 kV for electrical lines
±1 kV for input/output lines >
3 m
The power supply line quality should be that of a typical
commercial or hospital environment.
Overvoltage
IEC 61000-4-5
± 1 kV differential
mode
± 2 kV standard mode
The power supply line quality should be that of a typical
commercial or hospital environment.
Voltage drops, short
interruptions and
voltage change on the
IEC 61000-4-11 input
electric line
Ut = 0% (at 0°, 45°,
90°, 135°, 180°, 225°,
270°, 315°) for 0.5 cycles
Ut = 0% per 1 cycle
Ut = 70% (a 0°) per 25/30
cycles
Ut = 0% per 250/300 cycles
The power supply line quality should be that of a typical
commercial or hospital environment. If the dental unit
user requires a continuous operation also in case of
blackout, it is recommended to power the dental unit
with uninterruptible power supply or batteries.
Magnetic field at
network frequency
(50/60 Hz)
IEC 61000-4-8
The magnetic fields at network frequency should
feature levels typical of a standard commercial or
hospital environment.
