W
Recommended separation distances between portable and mobile RF
communications equipment and the device
.
The device is intended for use in an electromagnetic environment in which
radiated
therefore disturbances are controlled. The customer or the user of the
device can help
prevent electromagnetic interference by maintaining a
minimum distance between portable
and mobile RF communications
equipment (transmitters) and the device 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 metres (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 th
e 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.
