Recommended separation distances between portable and mobile RF communications equipment and MADSEN Alpha OAE+
The MADSEN Alpha OAE+ is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
the MADSEN Alpha OAE+ can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the MADSEN Alpha OAE+ 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.
