Recommended separation distance between portable and mobile RF communications equipment and the Össur
Myoelectric Prosthetic Devices
Össur Myoelectric Prosthetic Devices are intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customers or the user of Össur Myoelectric Prosthetic Devices can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Össur Myoelectric Prosthetic Devices 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 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.
DISPOSAL
All components of the product and packaging should be disposed of in accordance with respective national
environmental regulations. Users should contact their local governmental office for information on how these
items can be disposed of in an environmentally sound manner.
