Recommended separation distance
between portable and mobile RF
communications equipment and ClearUP
ClearUP® is intended for use in the
electromagnetic environment in which radiated
RF disturbances are controlled. The customers
or the users of ClearUP can help prevent
electromagnetic interference by maintaining a
minimum distance between portable and mobile
RF communications equipment (transmitters)
and ClearUP as recommended below,
according 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.
