Separation distance
Compatible accessories and peripherals
SonoSite has tested the Edge ultrasound system with the following accessories and peripherals and
has demonstrated compliance to the requirements of IEC60601-1-2:2007.
Recommended separation distances between portable and mobile RF communications
equipment and the Edge ultrasound system
The Edge ultrasound system is intended for use in an electromagnetic environment in which
radiated radio frequency (RF) disturbances are controlled. The customer or the user of the
Edge ultrasound system can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment
(transmitters) and the Edge ultrasound system 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) 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: At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
