Guidance and Manufacturer's declaration - Electromagnetic immunity
The dental unit is designed to operate in the specified electromagnetic environment. The customer or user of the dental unit must
ensure that it is used in such environment.
Electromagnetic Environment
The RF communication devices (portable and mobile)
must not be used at a distance from the dental unit and
its components, including cables, lower than the
recommended distance calculated using the
corresponding equation applicable to the transmitter
frequency.

Recommended distance between the RF portable and mobile communication devices and the dental unit.
The dental unit is intended for use in electromagnetic environment where RF irradiated disturbances are controlled. The customer or
the user of the dental unit can prevent electromagnetic interferences by ensuring a minimum distance between RF mobile and
portable (transmitter) communication devices and the dental unit as shown below, according to maximum power output of the
communication devices.
