SECTION 8: ELECTROMAGNETIC COMPATIBILITY (EMC)
The Precise® LTM 5 Watt Soft Tissue Diode Laser needs special precautions regarding the EMC and needs to be
installed and put into service according the EMC information provided in this manual.
Portable and mobile RF communications equipment can affect the Precise LTM. The use of accessories, transducer,
and cables other than those specied by the manufacture, CAO Group may result in increased emissions or
decreased immunity of the Precise LTM. The Precise LTM should not be used adjacent to or stacked with other
equipment and that if adjacent or stacked use is necessary, the Precise LTM should be observed to verify normal
operation in the conguration in which it will be used.
Guidance and manufacturer’s declaration - electromagnetic emissioins
The Precise® LTM is intended for use in the electromagnetic environment specied below.
The customer or the user of the Precise LTM laser should assure that it is used in such an environment.
Emissions Test Compliance
RF emissions
CISPR 11
Group 1 The Precise LTM laser 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.
