Technical Specification
Recommended separation distances between portable and mobile RF communications equipment and the MAT/PROPLUS/PUMP
Alternating Control Unit
The MAT/PROPLUS/PUMP is intended for use in an electromagnetic environment in which radiated 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.

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 separation distance for 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 separation distances between portable and mobile RF communications equipment and the EQUIPMENT
or SYSTEM - for ME EQUIPMENT or ME SYSTEM that are not LIFE - SUPPORTING
