How to Practice Voluntary Control
In this measure of voluntary control the member is obliged to assure that the strength of the disturbance from his products is contained below VCCI specified level before distributing them in Japan.
Before the shipment of his product the member shall file conformity verification report to VCCI based on the MME Class of the product in question and affix the VCCI mark of the Class on the product. The whole scheme of voluntary control is indicated in the following chart.
Categorization of Equipment
An MME shall apply as either of the two classes, Class A equipment and Class B equipment. The requirements for Class B equipment are intended to offer adequate protection to broadcast services within the residential environment. Equipment primarily intended for use in a residential environment shall meet the Class B limits. All other equipment shall comply with the Class A limits. A broadcast receiver equipment is a Class B equipment.
Confirmation of Compliance
The member manufacturers should verify that their MME products conform to the permissible tolerance of the technical requirements established by the Council.
The member manufacturers are required to verify technical requirement conformity and submit a report as indicated below.
- Confirmation of Compliance with Technical Standards
The member manufacturers should perform conformity verification tests on their MME products to confirm that their MME products meet the technical requirements established by the Council. Conformity verification tests shall be performed at measurement facilities, which are accredited and registered according to "Registration of Measurement Facilities".
- Registration of Compliance
The member manufacturers performing conformity verification testing of their MME product(s) should present a "Conformity Verification Report," using the specified form to the Council for its approval prior to shipment of the MME products.
Note: It takes about one week to issue a verification of acceptance of the "Conformity Verification Report."
Marking on Equipment
Members shall put the statement and/or the mark shown below on equipment that they have registered. The wording of the statement may be regarded as an example but shall include the Japanese text either exactly the same as the example or substantially similar to the example. For products with display means, “electronic display” may be implemented instead of the statement and/or the mark.
1. Class A equipment
Members shall put the statement and/or the mark shown below at a readily visible position on each Class A equipment that they have registered. The wording of the statement may be regarded as an example but shall include the Japanese text either exactly the same as the example or substantially similar to the example. Where it is difficult to put such statement and/or mark directly on the equipment, a tag may be used for such marking on the equipment.
This is a Class A equipment. Operation of this equipment in a residential environment could cause radio interference. In such a case, the user may be required to take corrective actions.
(The color of the mark is unrestricted.)
Note 1: The characters shall not be less than 2 mm high in principle. Where space is limited, the character size may be uniformly reduced as long as the characters are readable.
Note 2: VCCI-A means that the equipment meets the Class A limits.
2. Class B equipment
Members shall put the mark shown below at a readily visible position on each Class B equipment that they have registered.
(The color of the mark is unrestricted.)
Scope of Application
The Voluntary Control applies to the multimedia equipment(MME) to be shipped for the domestic market in Japan.
The following equipment may be exempted from these Rules:
- MME where the function of information technology equipment is not deemed its primary function or is not included.
- MME subject to other standards or laws equivalent in objective to these Rules in Japan, even if the definition of MME applies. Such MMEs include all radio-only equipment whose primary function is radio transmission and reception as stipulated in the Radio Law as well as electrical appliances stipulated in the Electrical Appliance and Material Safety Law.
- Equipment for which the emission requirements in the frequency range subject to these Rules are explicitly defined in other CISPR standards (except CISPR 13 and CISPR 22). Such equipment includes MMEs dedicated to industrial, scientific, and medical (ISM) purposes or dedicated to in-vehicle purposes.
- Equipment for use in telecommunications facilities to be installed only inside buildings controlled by telecommunications common carriers who provide such facilities and services.
- Equipment for use in broadband power line communication facilities (in the frequency range 2 MHz to 30 MHz prescribed in Regulations for Enforcement of the Radio Law, Article 44-2-2).
- MME whose power consumption is 6 nW or less.
Definition of Terms
- multimedia equipment (MME)
- Equipment that is information technology equipment, audio equipment,video equipment, broadcast receiver equipment, entertainment lighting control equipment or combinations of these.
- Operation carried out by an MME.
Note: Functions are related to basic technologies incorporated in the MME, such as displaying, recording, processing, controlling, reproducing, transmitting, or receiving single medium or multimedia content. The content may be data, audio or video, either individually or in combination.
