A-5User’s Guide • Aaron 950™
Recommended separation distances between portable and mobile RF
communications equipment and the Aaron 950™
The Aaron 950™ is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Aaron 950™ can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Aaron 950™ as recommended below, accord-
ing 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 metres (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.
