•NEC Electronics products are classified into the following three quality grades: "Standard", "Special" and
"Specific".
The "Specific" quality grade applies only to NEC Electronics products developed based on a customer-
designated "quality assurance program" for a specific application. The recommended applications of an
NEC Electronics product depend on its quality grade, as indicated below. Customers must check the
quality grade of each NEC Electronics product before using it in a particular application.
"Standard": Computers, office equipment, communications equipment, test and measurement
equipment, audio and visual equipment, home electronic appliances, machine tools,
personal electronic equipment and industrial robots.
"Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems,
anti-disaster systems, anti-crime systems, safety equipment and medical equipment
(not specifically designed for life support).
"Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control
systems, life support systems and medical equipment for life support, etc.
The quality grade of NEC Electronics products is "Standard" unless otherwise expressly specified in NEC
Electronics data sheets or data books, etc. If customers wish to use NEC Electronics products in applications
not intended by NEC Electronics, they must contact an NEC Electronics sales representative in advance to
determine NEC Electronics' willingness to support a given application.
(Note)
(1) "NEC Electronics" as used in this statement means NEC Electronics Corporation and also includes its
majority-owned subsidiaries.
(2) "NEC Electronics products" means any product developed or manufactured by or for NEC Electronics (as
defined above).

For customers in the European Union only
Redemption of Waste Electrical and Electronic Equipment
(WEEE) in accordance with legal regulations applicable in the
European Union only: This equipment (including all
accessories) is not intended for household use. After use the
equipment cannot be disposed of as household waste. NEC
Electronics (Europe) GmbH offers to take back the equipment.
All you need to do is register at http://www.eu.necel.com/weee
CAUTION
This is a Test- and Measurement equipment with possibility to be significantly
altered by user through hardware enhancements/modifications and/or test or
application software. Thus, with respect to Council Directive 89/336/EEC
(Directive on compliance with the EMC protection requirements), this equipment
has no autonomous function. Consequently this equipment is not marked by the
CE-symbol.
EEDT-ST-005-10
CAUTION
This equipment should be handled like a CMOS semiconductor device. The
user must take all precautions to avoid build-up of static electricity while
working with this equipment. All test and measurement tool including the
workbench must be grounded. The user/operator must be grounded using
the wrist strap. The connectors and/or device pins should not be touched
with bare hands.
