For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (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 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.

Recommended protective distances between
portable and mobile RF telecommunication devices
and the system
The system is intended for use in an electromagnetic environment in which radi-
ated RF disturbances are controlled. The customer or the user of the system can
help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and
the system as recommended below, according to the maximum output power of
the communications equipment.
