Sony PDW-75MD Instructions For Use Manual page 7

Recommended separation distances between portable and mobile RF communications equipment and the PDW-75MD
The PDW-75MD is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the PDW-75MD can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the PDW-75MD 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.
WARNING on power connection
Use a proper power cord for your local power supply.
1. Use the approved Power Cord (3-core mains lead) /
Appliance Connector / Plug with earthing-contacts that
conforms to the safety regulations of each country if
applicable.
2. Use the Power Cord (3-core mains lead) / Appliance
