RECOMMENDED SPACING BETWEEN A PORTABLE AND MOBILE
COMMUNICATION APPLIANCE AND THE COMPEX RUNNER
The Compex Runner is designed for use in an electromagnetic environment
in which radiated RF waves are controlled. The buyer or user of the Compex
Runner can contribute to preventing electromagnetic interference by
maintaining a minimum distance between RF portable and mobile
communication appliances (transmitters) and the Compex Runner according
to the table of recommendations below and according to the maximum
output power of the telecommunication appliance.

From 150 kHz to
80 MHz
d = 1.2 √P
From 80 MHz to
800 MHz
d = 1.2 √P
From 800 MHz to
2.5 GHz
d = 2.3 √P

0.1 0.38 0.38 0.73
1 1.2 1.2 2.3
10 3.8 3.8 7.3
100 12 12 23
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.
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 modied by
absorption and reection due to buildings, objects and persons.
