Table 4: Recommended separation distances between portable and mobile RF communications
equipment and the model Rooter
®
X3000
The model Rooter
®
X3000 is intended for use in electromagnetic environment in which radiated RF disturbances
is controlled. The customer or the user of the model Rooter
®
X3000 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the model Rooter
®
X3000 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) accordable 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.
