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

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be esti-
mated 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 1 To calculate the recommended separation distance of transmitters in the frequency range of 80 MHz and 800 MHz to 2.5 GHz, an
additional factor of 10/3 has been used in order to reduce the probability of a mobile/portable communications device unintentio-
nally introduced into the patient area causing a fault.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from struc-
tures, objects and people.
