Sony HMM-3000MT Gebrauchsanweisung Seite 16

Recommended separation distances between portable and mobile RF communications equipment
The HMM-3000MT is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the HMM-3000MT can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the HMM-3000MT 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.
