Recommended Separation Distances between Portable and Mobile RF
Communications Equipment and the GSI Pello
The GSI Pello is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the GSI Pello can help prevent electromagnetic interferences by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters) and the GSI Pello 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 transmitters, 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 higher frequency range applies.
Note 2
: These guidelines may not apply to all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
