Table 16: Separation Distance
Recommended separation distance between portable and mobile RF communications equipment and
the Model 9010 Programmer System
The Model 9010 Programmer System is intended for use in the electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Model 9010 Programmer
System can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Model 9010 Programmer
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.
