When intending to use any our product with automotive application and the other application than ordinary electronic equipments as above, please contact our sales representatives in advance. by blending the essence of these three efficiency technologies. The essence of these technologies is represented in each of the prod- ucts that we provide to our customers. In the industrial sector, leading priorities include measures to counter the greenhouse effect by reducing CO2, measures to pre- serve the global environment, and the development of energy-effi- cient products. Environmental problems are of global concern, and although the contribution of energy-saving technology developed by EPSON may appear insignificant, we seek to contribute to the development of energy-saving products by our customers through the utilization of our electronic devices. EPSON is committed to the conservation of energy, both for the sake of people and of the planet on which we live. EPSON offers effective savings to its customers through a wide range of electronic devices, such as semiconductors, liquid crystal display (LCD) modules, and crystal devices. These savings are achieved through a sophisticated melding of three different effi- ciency technologies. Power saving technology provides low power consumption at low voltages. Space saving technology provides further reductions in product size and weight through super-precise processing and high-density assembly technology. Time saving technology shortens the time required for design and development on the customer side and shortens delivery times. Our concept of Energy Saving technology conserves resources Co-existence Mark The environmental mark symbolizing Epson's basic stance of "Co-existence with Nature". The design incorporates a fish, flower, and water, representing mutually supportive co- existence. ISO14000 is an international standard for environmental management that was established by the International Standards Organization in 1996 against the background of growing concern regarding global warming, destruction of the ozone layer, and global deforestation. QS-9000: This is an enhanced standard for quality assurance systems formulated by leading U.S. automobile manufacturers based on the international ISO 9000 series. WORKING FOR HIGH QUALITY Seiko-Epson quickly began working to acquire company-wide ISO9000 series certification, and has acquired ISO9001 or ISO9002 certification with all targeted products manufactured in Japanese and overseas plants. The Quartz Device Operations Division, EPM and SZE have acquired QS-9000 certification, which are of higher level. WORKING WITH ENVIRONMENTAL ISSUES In 1988, Seiko Epson led in working to abolish CFCs, and perfect abolition of those ozone layer-destroying substances was achieved in 1992. In 1998, the 10th year of start of the CFC-free activity, Seiko Epson set this year as the "Second Environmental Benchmark Year" and established a new corporate General Environmental Policy. Seiko Epson is tackling with environmental issues comprehensively. At the end of Fiscal 1988, Seiko Epson succeeded in abolishing chloric solvents doubted to be harmful to human body. In fiscal 1999, Seiko Epson started the activity with a goal of abolishing lead solder pointed out possibility of enironmental pollutant. Promotion of Environment Management System conforming to International Standard To strengthen management for environmental activities, Seiko Epson Group aims at acquisition of the ISO14001 certification for Japanese and abroad main business bases (including affiliates) for manufacturing, sales, software development and others. As of May 25 , 2001, planned 68 bases of all manufacturing bases and some non-manufacturing bases have acquired the certification. ENERGY SA VING EPSON THE CRYSTALMASTER
