Recommended Separation Distances
The LUKE arm system is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The user of the LUKE arm system
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
LUKE arm system as recommended below, according to the maximum output
power of the communications equipment.
defines the recommended separation distances between
portable and mobile RF communications equipment and the LUKE arm system.

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, 460 MHz, 470 MHz, 690 MHz, 800 MHz, 965 MHz, and 1.39 GHz, 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.
