The
TNI
soft
Flow
50
is intended for use in the electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the “
TNI
soft
Flow
50
” can help
prevent electromagnetic interference by maintaining a miminum distance between portable
and mobile RF communications equipment (transmitters) and the “
TNI
soft
Flow
50
” as recom-
mended below, according to the maximum output power of the communication equipment.

For transmitters rated at a maximum output power not listed above, the recommended separa-
tion distance d in metres (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 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 af-
fected by absorption and reflection from structures, objects and people.
