4. You should not alter, modify, copy, or otherwise misappropriate any Renesas Electronics product, whether in whole or in part. California Eastern
Laboratories and Renesas Electronics assume no responsibility for any losses incurred by you or third parties arising from such alteration, modication, copy
or otherwise misappropriation of Renesas Electronics product.
5. Renesas Electronics products are classied according to the following two quality grades: “Standard” and “High Quality”. The recommended applications
for each Renesas Electronics product depends on the product’s quality grade, as indicated below. “Standard”: Computers; ofce equipment; communications
equipment; test and measurement equipment; audio and visual equipment; home electronic appliances; machine tools; personal electronic equipment; and
industrial robots etc. “High Quality”: Transportation equipment (automobiles, trains, ships, etc.); trafc control systems; anti-disaster systems; anti-crime
systems; and safety equipment etc. Renesas Electronics products are neither intended nor authorized for use in products or systems that may pose a direct
threat to human life or bodily injury (articial life support devices or systems, surgical implantations etc.), or may cause serious property damages (nuclear
reactor control systems, military equipment etc.). You must check the quality grade of each Renesas Electronics product before using it in a particular
application. You may not use any Renesas Electronics product for any application for which it is not intended. California Eastern Laboratories and Renesas
Electronics shall not be in any way liable for any damages or losses incurred by you or third parties arising from the use of any Renesas Electronics product
for which the product is not intended by California Eastern Laboratories or Renesas Electronics.
6. You should use the Renesas Electronics products described in this document within the range specied by California Eastern Laboratories, especially with
respect to the maximum rating, operating supply voltage range, movement power voltage range, heat radiation characteristics, installation and other product
characteristics. California Eastern Laboratories shall have no liability for malfunctions or damages arising out of the use of Renesas Electronics products
beyond such specied ranges.
7. Although Renesas Electronics endeavors to improve the quality and reliability of its products, semiconductor products have specic characteristics such as
the occurrence of failure at a certain rate and malfunctions under certain use conditions. Further, Renesas Electronics products are not subject to radiation
resistance design. Please be sure to implement safety measures to guard them against the possibility of physical injury, and injury or damage caused by
re in the event of the failure of a Renesas Electronics product, such as safety design for hardware and software including but not limited to redundancy,
re control and malfunction prevention, appropriate treatment for aging degradation or any other appropriate measures. Because the evaluation of
microcomputer software alone is very difcult, please evaluate the safety of the nal products or systems manufactured by you.
8. Please contact a California Eastern Laboratories sales ofce for details as to environmental matters such as the environmental compatibility of each Renesas
Electronics product. Please use Renesas Electronics products in compliance with all applicable laws and regulations that regulate the inclusion or use of
controlled substances, including without limitation, the EU RoHS Directive. California Eastern Laboratories and Renesas Electronics assume no liability for
damages or losses occurring as a result of your noncompliance with applicable laws and regulations.
9. Renesas Electronics products and technology may not be used for or incorporated into any products or systems whose manufacture, use, or sale is prohibited
under any applicable domestic or foreign laws or regulations. You should not use Renesas Electronics products or technology described in this document
for any purpose relating to military applications or use by the military, including but not limited to the development of weapons of mass destruction. When
exporting the Renesas Electronics products or technology described in this document, you should comply with the applicable export control laws and
regulations and follow the procedures required by such laws and regulations.
10. It is the responsibility of the buyer or distributor of California Eastern Laboratories, who distributes, disposes of, or otherwise places the Renesas Electronics
product with a third party, to notify such third party in advance of the contents and conditions set forth in this document, California Eastern Laboratories and
