MPS 3 System – Appendix
17.1.3.Recommended Separation Distance
Guidance and Manufacturer’s Declaration – Recommended Separation Distance
The MPS 3 System is intended for use in an environment in which radiated RF disturbances are
controlled. The customer or the operator of the device can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the device as recommended below, according to the maximum output power of the
communications equipment.

d = 1.2 √ P
800 MHz to 2.5 GHz
d = 2.3 √ P

1 1.2 1.2 2.3
10 3.8 3.8 7.3
100 12 12 23
For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (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 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, people, and animals.
