In the case of transmitters whose maximum output power is not shown in the table above, the
recommended spacing of d metres (m) can be calculated using the appropriate equation for the
transmitter frequency, where P is the maximum output power of the transmitter in watts (W) as
set by the transmitter manufacturer.
The Compex Performance is designed for use in an electromagnetic
environment in which radiated RF waves are controlled. The buyer or user of
the Compex Performance can contribute to preventing electromagnetic
interference by maintaining a minimum distance between RF portable and
mobile communication appliances (transmitters) and the Compex
Performance according to the table of recommendations below and
according to the maximum output power of the telecommunication
appliance.
RECOMMENDED SPACING BETWEEN A PORTABLE AND MOBILE
COMMUNICATION APPLIANCE AND THE COMPEX PERFORMANCE
NOTE 1: At 80 MHz and at 800 MHz,
the spacing for high frequency amplitude is applied.
NOTE 2: These guidelines may not be appropriate for some
situations. Electromagnetic wave propagation is modified by
absorption and reflection due to buildings, objects and persons.
