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