For all EQUIPMENT and SYSTEMS
NOTE:
To protect from EMI, please leave the DUS 60 system away from the EMI sources. For
the technical reasons, electromagnetic immunity is limited to 1 Vrms, otherwise, the
interfaced images may affect the diagnosis and measurements.
Guidance and manufacture’s declaration-electromagnetic emission
The DUS 60 is intended for use in the electromagnetic environment specified below; The customer or
the user of the DUS 60 should assure that it is used in such and environment.
Emission test Compliance Electromagnetic environment-guidance
RF emissions
CISPR 11
Group 1 The DUS 60 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.
