Important Service Information
RoHS (2002/95/EC) Requirements – Applied to all countries require RoHS.
The RoHS (Restriction of Hazardous Substance in Electrical and Electronic Equipment Directive) is a
legal requirement by EU (European Union) for the global electronics industry which sold in EU and
some counties also require this requirement. Any electrical and electronics products launched in
the market after June 2006 should meet this RoHS requirements. Products launched in the market
before June 2006 are not required to compliant with RoHS parts. If the original parts are not RoHS
complaints, the replacement parts can be non ROHS complaints, but if the original parts are RoHS
compliant, the replacement parts MUST be RoHS complaints.
If the product service or maintenance require replacing any parts, please confirming the RoHS
requirement before replace them.

Customer Acceptance
1.0 SCOPE
This document establishes the general workmanship standards and functional acceptance criteria
for PROJECTOR produced by Qisda.
2.0 PURPOSE
The purpose of this publication is to define a procedure for inspection of the PROJECTOR by
means of a customer acceptance test, the method of evaluation of defects and rules for
specifying acceptance levels.
3.0 APPLICATION
The "Customer Acceptance Criteria" is applicable to the inspection of the PROJECTOR,
completely packed and ready for dispatch to customers. Unless otherwise specified, the customer
acceptance inspection should be conducted at manufacturer's site.
4.0 DEFINITION
The "Customer Acceptance Criteria" is the document defining the process of examining, testing
or otherwise comparing the product with a given set of specified technical, esthetic and
workmanship requirements leading to an evaluation of the "degree of fitness for use", including
possible personal injury or property damage for the use of the product.
5.0 CLASSIFICATION OF DEFECTS
The defects are grouped into the following classes:
5.1 Critical defect
A critical defect is a defect which judgment and experience indicate that there is likely to
result in hazardous or unsafe conditions for individuals using product.
5.2 Major defect
A major defect is a defect, other than critical one, is likely to result in failure, or to reduce
materially the usability of the product for its intended purpose.
5.3 Minor defect
A minor defect is a defect that is not likely to reduce materially the usability of its intended
purpose, or is a departure from established standards having little bearing on the effective
use of operation of the product.
Note: If BenQ defect undefined failure, and it judged that is reduce the merchandisebility,
BenQ CM Inform this defect. After that parties make communication and decide how to solve.

7.0 INSPECTION STANDARD
Unless otherwise specified, the inspection standard will be defined by MIL-STD-105E,
NORMAL INSPECTION LEVEL Ⅱ, SINGLE SAMPLING PLAN. Level Ⅱ is in use all the time,
inspection levels are normal, reduce and tighten.
7.1 Acceptance Quality Level
7.1.1 Critical Defect:
When a critical defect is found, this must be reported immediately upon detection, the
lot or batch shall be rejected and further shipments shall be held up pending instructions
from the responsible person in relevant department.
7.1.2 under normal sampling
Critical Defective : 0% AQL
Major Defective : 0.65% AQL
Minor Defective : 2.5% AQL
7.1.3 under special sampling
Critical Defective : 0% AQL
Major Defective : 1.0% AQL
Minor Defective : 4.0% AQL
8.0 GENERAL RULES
8.1 The inspection must be carried out by trained inspectors who have good knowledge about
