Stryker Isolibrium 2971 Manuel D'utilisation Et D'entretien page 99

Recommended separation distances between portable and mobile RF communications equipment and
Isolibrium is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of Isolibrium can help prevent electromagnetic interferences by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and Isolibrium 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 meters
(m) can be estimated 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.
Note: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
