operation of the appliances shall be provided to the user. The
following content describes the relevant technical description of EMC.
(Refer to Y0505-2012 for details)
The basic performance of this product described in the scope of
application will not be affected by the electromagnetic environment
stipulated in the EMC technical data.
■ Definition of EMC (electromagnetic compatibility)
EMC (electromagnetic compatibility) refers to the capability to satisfy
the following two requirements.
1. It shall not send electromagnetic interference sounds outside the
permitted range to other nearby electronic equipment. (Radiation)
2. The equipment can play its normal function in the electromagnetic
environment where other electronic equipment sends out noise.
(Immunity)
■ Technical description related to EMC
(electromagnetic compatibility)
Medical electrical equipment shall be provided with special
instructions about EMC and shall be used in accordance with the EMC
information described below.
1. This product requires special instructions related to
electromagnetic compatibility (EMC). Please use this product
according to the EMC information described in this manual.
2. Portable and radio frequency (RF) communication equipment may
affect this product.
3. Do not use this product adjacent to or stacked with other equipment.
(Except for communication)
4. Do not use products other than special accessories, otherwise ithey
may increase the radiation and decrease the immunity.
Warning:
apart from the cables sold by the equipment or system
manufacturer as spare parts of internal parts and components, the
use of other accessories and cables may increase the equipment or
system's emission or decrease the immunity.
