Recommended Separation Distances Between Portable and Mobile RF Communications Equipment and the Eko Electronic Stethoscope System
DUO is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The user of DUO can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and DUO as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d is meters (m) can be estimated using the equation applicable to the frequency of the transmitter,
where P is the maximum 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.
