Mectron PIEZOSURGERY touch Mode D'emploi page 32

Recommended separation distances between portable and mobile RF
The PIEZOSURGERY® touch is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or user of the PIEZOSURGERY®
touch can help prevent electromagnetic interference by maintaining a minimum distance
EN
between portable and mobile FR communications equipment (transmitters) and the
PIEZOSURGERY® touch as recommended below, according to the maximum output power of
the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in metres (m) can be calculated using the equation applicable to
the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
N.B.:
(1) at 80 MHz and 800 MHz, the higher frequency range applies.
(2) These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
