WMP-153 User’s manual
7
The model WMP-153 is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The
customer or the user of the model WMP-153 can help prevent
electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment
(transmitters) and the model WMP-153 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 distanced
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.
