Faro DKL L2-ECO Notice D'utilisation page 263

The ALYA lamp is designed to function in an electromagnetic environment in which disturbances from RF emissions are kept under
control. The client or operator of the unit can contribute to preventing electromagnetic interference by assuring a minimum distance
between mobile and portable RF communication devices (transmitters) and the dental unit, as recommended below, in relation to the
maximum output power of the radio-communication devices.
Maximum
nominal output power
of the transmitter
For transmitters with a maximum nominal power emission not listed above, the recommended separation distance d in metres (m)
can be calculated using the equation applied to the transmitter frequency, where P is the maximum nominal power emission of the
transmitter in Watts (W) according to the manufacturer.
Note:
At 80 MHz and 800 MHz, the highest interval is applied.
These guidelines may not apply in all situations. Electromagnetic propagation is influenced by the absorption and reflection of
structures, objects and people.
