Recommended separation distances between portable and mobile RF communications equipment and the Opton
device
The Opton device is intended for use in the electromagnetic environments where RF disturbances are controlled. The
customer or the user of the Opton device can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the Opton device as recommended below,
according to the maximum output power of the communications devices listed below.

For transmitters whose maximum nominal output in the above table is not specified, the recommended separation distance d
in meters (m) can be determined using the equation given for the corresponding column, where P is the maximum output
power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 Hz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all cases. The electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
