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
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
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.

Uscan has Class A compliance in meaning it is suitable for use in all establishments other than domestic and those directly connected to the
public low-voltage power supply network that supplies buildings used for domestic purposes. If Uscan is found to cause or respond to
interference follow the guidelines in the warning section above

Electromagnetic environment: guidance
Uscan uses RF energy only for its internal function. Therefore, its RF emissions are very
low and are not likely to cause any interference in nearby electronic equipment.
Uscan is suitable for use in all establishments other than domestic and those directly
connected to the public low-voltage power supply network that supplies buildings used for
domestic purposes.
