Sony UP-D898DC Bedienungsanleitung Seite 23

Recommended separation distances between portable and mobile RF
communications equipment and the UP-D898DC
The UP-D898DC is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the UP-D898DC
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
UP-D898DC as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated 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.
Caution
When you dispose of the unit or accessories, you must obey the laws in the relative area or
country and the regulations in the relative hospital regarding environmental pollution.
