Recommended separation distances between
portable and mobile RF communications equipment and the not life support equipment
The Product is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the
user of the Product can help prevent electromagnet interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Product 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 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 higher frequency range applies.
Note 1:
At 80 MHz and 800 MHz, the separation distance fort 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.
