Electromagnetic compatibility (EMC)
Caution
 Uscan contains sensitive components and circuits. Failure to observe proper static control procedures
may result in damage to the system. Any faults should be reported to Signostics
or your Uscan
distributor for repair.
Warning
 Uscan complies with the Electromagnetic Compatibility requirements of AS/NZ CISPR 11:2004 and
IEC 60601-1-2:2007. However, electronic and mobile communications equipment may transmit
electromagnetic energy through air and there is no guarantee that interference will not occur in a
particular installation or environment. Interference may result in artifacts, distortion, or degradation of
the ultrasound image. If Uscan is found to cause or respond to interference, try re-orienting Uscan or
the affected device, or increasing the separation distance between the devices. Contact Signostics
customer support or your Signostics distributor for further information.
The Uscan is intended for use in the electromagnetic environment specified below. The user of the Uscan
should assure that it is used in such an environment.
