Recommended separation distances between portable and mobile RF communications equipment and the Cast Cutter (REF 0941-000-000)
The Cast Cutter (REF 0941-000-000) is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The customer or
the user of the Cast Cutter (REF 0941-000-000) can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the Cast Cutter (REF 0941-000-000) 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.
NOTE 1:
At 80 MHz and 800 MHz, 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.
