Recommended separation distances between mobile and portable RF communications equipment and the Saphyr
The Saphyr is designed to be used in an electromagnetic environment in which radiated RF disruption is controlled.
The user of the Saphyrmay contribute to avoiding the electromagnetic interference while keeping a minimal distance
between mobile and portable RF communications equipment (transmitter) and the Saphyr, as recommended below,
depending on the maximum power of transmission of the communications equipment.

For transmitters where the assigned maximum emission power is not given above, the recommended separation distance,
d, in metres (m) can be estimated by using the applicable equation at the frequency of the transmitter, where P is the
characteristic of the maximum power of emission of the transmitter in watts (W), depending on the manufacturer of the latter.
NOTE 1: At 80 MHz and at 800 MHz the distance of separation for the highest frequency range applies.
NOTE 2: These directives may not apply in all situations. Electromagnetic propagation is modified by absorption and by
reflections from structures, objects and people.
