Brainlab KICK 2 - RF Communications Equipment

7.4.4 RF Communications Equipment
Electromagnetic Environment
Portable and mobile RF communications equipment can affect the systems.
The Kick 2 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled.
The Kick 2 user can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the Kick
2 as recommended below, according to the maximum output power of the communications
equipment.
Separation Distances
Recommended separation distances between portable and mobile RF communications equipment
and the Kick 2:
Rated Maximum Out-
put Power of Trans-
mitter (W)
Separation Distance According to Frequency of Transmitter (m)
150 kHz to 80 MHz
d 1 2 P,=
80 MHz to 800 MHz
d 1 2 P,=
800 MHz to 2.5 GHz
d 2 3 P,=
0.01 0.12 0.12 0.23
0.1 0.37 0.37 0.74
1 1.2 1.2 2.3
10 3.7 3.7 7.4
100 12 12 23
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.
