Recommended separation distances between portable and mobile RF communications equipment and the T/
Pump.
The T/Pump system is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the T/Pump system can help prevent electromagnetic interferences by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the
T/Pump 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:
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note:
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.
The T/Pump system is suited for use in the electromagnetic environment specified below. The customer or the user
of the T/Pump system should ensure that it is used in such an environment.
