Non-invasive Spine Fusion Stimulator System
The Biomet

SpinalPak
®
Non-invasive Spine Fusion Stimulator System is intended for use in an
electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user
of the Biomet
®
SpinalPak
®
Non-invasive Spine Fusion Stimulator System can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile communications equipment
(transmitters) and the Biomet

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 applies.
NOTE 2. These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
