Table 6-8. Recommended separation distances between portable and mobile radio frequency
(RF) communication equipment and the Model 8930 Radio Frequency Generator .
The Model 8930 Radio Frequency Generator is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the user of the
generator can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the generator
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.
Notes:
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
■
These guidelines may not apply in all situations. Electromagnetic propagation is affected by
■
absorption and reflection from structures, objects, and people.
Cautions:
Do not use non-Medtronic components with Medtronic in-line-powered external devices.
■
The use of non-Medtronic components may result in damage to Medtronic components,
increased emissions, or decreased electromagnetic immunity of the Medtronic devices or
systems.
Do not use Medtronic in-line-powered external devices adjacent to, or stacked with, other
■
electronic devices. Using Medtronic devices in these configurations may result in
decreased electromagnetic immunity of the Medtronic devices or systems.
RF Cable: The Medtronic Prostiva RF Therapy Model 8929 radio frequency cable is
approximately 2.7 m in length.
