9�4 Recommended Separation Distance Of Other Equipment - Boston Scientific LithoVue Manuel D'utilisation

a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the LithoVue System is used exceeds the applicable RF compliance level above, the LithoVue System should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the LithoVue System.
b) Over the frequency range 150 kHz to 80 MHz, the field strengths should be less than 3 V/m.

The LithoVue™ System is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. You should help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters)
and the LithoVue System as recommended below, according to the maximum output power of the
communications equipment (Table 9.4).

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 of the transmitter in watts (W) according to the manufacturer.
note 1 – At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
note 2 – These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
