9.5.3 RF Communications Equipment
Electromagnetic Environment
Warning
Portable RF communications equipment (including peripherals like antenna cables and
external antennas) should not be used closer than 30 cm from any part of the Kick 2
Navigation Station including cables specified by Brainlab. Otherwise, degradation of the
performance could result.
Separation Distances
The Kick 2 Navigation Station system is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled.
The Kick 2 Navigation Station system user can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the
Kick 2 Navigation Station system 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 separa-
tion distance d in meters (m) can be determined 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: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
