This device is for use in professional healthcare facility environments only.
With the installation of the device, use only the delivered external cables and power supply or a spare part provided by the legal manufacturer. Using another can result in a decrease of the immunity level of the device.
The MDNC-3421 is intended for use in the electromagnetic environment specified below. The customer or the user of the MDNC-3421 should assure that it is used in such an environment.
| Emissions test | Compliance | Electromagnetic environment – Guidance |
RF emissions CISPR 11 | Group 1 | The MDNC-3421 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. |
RF emissions CISPR 11 | Class B | The MDNC-3421 is suitable for use in all establishments, including domestic establishments and those directly connected to the public low-voltage power supply network that supplies buildings used for domestic purposes. |
Harmonic emissions IEC 61000-3-2 | Class D | |
Voltage fluctuations/ flicker emissions IEC 61000-3-3 | Complies |
This MDNC-3421 complies with appropriate medical EMC standards on emissions to, and interference from surrounding equipment. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Interference can be determined by turning the equipment off and on.
If this equipment does cause harmful interference to, or suffer from harmful interference of, surrounding equipment, the user is encouraged to try to correct the interference by one or more of the following measures:
The MDNC-3421 is intended for use in the electromagnetic environment specified below. The customer or the user of the MDNC-3421 should assure that it is used in such an environment.
