2. Introduction
This section contains general service information, please read through carefully. It should
be stored for easy access place for quick reference.
2.1. 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.
2.2. Safety Notice
1. Make sure your working environment is dry and clean, and meets all government
safety requirements.
2. Ensure that other persons are safe while you are servicing the product.
DO NOT perform any action that may cause a hazard to the customer or make the product
unsafe.
3. Use proper safety devices to ensure your personal safety.
4. Always use approved tools and test equipment for servicing.
5. Never assume the product’s power is disconnected from the mains power supply.
Check that it is disconnected before opening the product’s cabinet.
6. Modules containing electrical components are sensitive to electrostatic discharge
(ESD). Follow ESD safety procedures while handling these parts.
7. Some products contain more than one battery. Do not disassemble any battery, or
expose it to high temperatures such as throwing into fire, or it may explode.
8.
Refer to government requirements for battery recycling or disposal.
2.3 .Compliance Statement
Caution: This Optical Storage Product contains a Laser device. Refer to the product
specifications and your local Laser Safety Compliance Requirements.
2.4. General Descriptions

3. Product Overview
Introduction
P221W is defined as our new 22’W model in acer P series which will be the first acer
project in Qisda. P221W is defined as 22’W LCD Monitor supports WSXGA+ resolution
with DPMS (Display Power Management System) and acer eColor function. There are
dual input types, D-sub, DVI. P221W adopts AUO panel, M220EW01 V0.
The features summary is shown as below,
*All panel spec. in C201 definition depends on the variance of panel source.
*All spec. of monitor need to warm up at least 1hr.
* To test the “Contrast Ratio” and “Luminance” functions, the color status must be
“User preset” mode.
* 1. “Contrast Ratio”: Set “brightness” at 100, and “contrast” at 50.
* 2. “Luminance”: Set “brightness” at 100, and “contrast” at 100.

When Vertical Frequency is over 75Hz or under 56Hz, but Pixel Clock is between
25.175MHz
And 187MHz, the monitor can show image, and the same time has “Input Not
Supported” warning message. If Pixel Clock is over the range of 25.175MHz ~
187MHz, the display is Black and show warning message.
2. If Hf /Vf is set in the range of 31KHz~83KHz and 56Hz ~75Hz, and Pixel Clock is set
in the range of 25.175MHz~187MHz, but is not the above Resolution, then it will
display the nearest mode.
3. When digital input, the maximum resolution is 1680x1050@60Hz
