Preface

Before using this information and the product it supports, please read the following general information.

1. This Service Guide provides you with all technical information relating to the BASIC CONFIGURATION decided

for Acer's "global" product offering. To better fit local market requirements and enhance product competitiveness,

your regional office may have decided to extend the functionality of a machine (e.g. add-on card, modem, or extra

memory capability). These LOCALIZED FEATURES will NOT be covered in this generic service guide. In such

cases, please contact your regional offices or the responsible personnel/channel to provide you with further

technical details.

2. Please note WHEN ORDERING FRU PARTS, that you should check the most up-to-date information available on

your regional web or channel. If, for whatever reason, a part number change is made, it will not be noted in the

printed Service Guide. For ACER-AUTHORIZED SERVICE PROVIDERS, your Acer office may have a

DIFFERENT part number code to those given in the FRU list of this printed Service Guide. You MUST use the list

provided by your regional Acer office to order FRU parts for repair and service of customer machines.

Warning: (For FCC Certified Models)

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to

Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in

a residential installation. This equipment generates, uses and can radiate radio frequency energy, and if not installed

and used in accordance with the instructions, may cause harmful interference to radio communications. However,

there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful

interference to radio or television reception, which can be determined by turning the equipment off and on, the user

is encouraged to try to correct the interference by one or more of the following measures:

1. Reorient or relocate the receiving antenna.

2. Increase the separation between the equipment and receiver.

3. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

4. Consult the dealer or an experienced radio/TV technician for help.

Notice:

1. The changes or modifications not expressly approved by the party responsible for compliance could void the

user's authority to operate the equipment.

2. Shielded interface cables and AC power cord, if any, must be used in order to comply with the emission limits.

3. The manufacturer is not responsible for any radio or TV interference caused by unauthorized modification to this

equipment. It is the responsibility of the user to correct such interference.

As ENERGY STAR

®

Partner our company has determined that this product meets the ENERGY STAR

®

guidelines for energy efficiency.

Warning:

To prevent fire or shock hazard, do not expose the monitor to rain or moisture. Dangerous high voltages are present

inside the monitor. Do not open the cabinet. Refer servicing to qualified personnel only.

4

Precautions

z Do not use the monitor near water, e.g. near a bathtub, washbowl, kitchen sink, laundry tub, swimming pool or in

a wet basement.

z Do not place the monitor on an unstable trolley, stand, or table. If the monitor falls, it can injure a person and

cause serious damage to the appliance. Use only a trolley or stand recommended by the manufacturer or sold

with the monitor. If you mount the monitor on a wall or shelf, uses a mounting kit approved by the manufacturer

and follow the kit instructions.

z Slots and openings in the back and bottom of the cabinet are provided for ventilation. To ensure reliable

operation of the monitor and to protect it from overheating, be sure these openings are not blocked or covered.

Do not place the monitor on a bed, sofa, rug, or similar surface. Do not place the monitor near or over a radiator

or heat register. Do not place the monitor in a bookcase or cabinet unless proper ventilation is provided.

z The monitor should be operated only from the type of power source indicated on the label. If you are not sure of

the type of power supplied to your home, consult your dealer or local power company.

z The monitor is equipped with a three-pronged grounded plug, a plug with a third (grounding) pin. This plug will fit

only into a grounded power outlet as a safety feature. If your outlet does not accommodate the three-wire plug,

have an electrician install the correct outlet, or use an adapter to ground the appliance safely. Do not defeat the

safety purpose of the grounded plug.

z Unplug the unit during a lightning storm or when it will not be used for long periods of time. This will protect the

monitor from damage due to power surges.

z Do not overload power strips and extension cords. Overloading can result in fire or electric shock.

z Never push any object into the slot on the monitor cabinet. It could short circuit parts causing a fire or electric

shock. Never spill liquids on the monitor.

z Do not attempt to service the monitor yourself; opening or removing covers can expose you to dangerous

voltages and other hazards. Please refer all servicing to qualified service personnel

z To ensure satisfactory operation, use the monitor only with UL listed computers which have appropriate

configured receptacles marked between 100 - 240V AC, Min. 5A.

z The wall socket shall be installed near the equipment and shall be easily accessible.

Special Notes on LCD Monitors

The following symptoms are normal with LCD monitor and do not indicate a problem.

Notes

z Due to the nature of the fluorescent light, the screen may flicker during initial use. Turn off the Power Switch and

then turn it on again to make sure the flicker disappears.

z You may find slightly uneven brightness on the screen depending on the desktop pattern you use.

z The LCD screen has effective pixels of 99.99% or more. It may include blemishes of 0.01% or less such as a

missing pixel or a pixel lit all of the time.

z Due to the nature of the LCD screen, an afterimage of the previous screen may remain after switching the image,

when the same image is displayed for hours. In this case, the screen is recovered slowly by changing the image

or turning off the Power Switch for hours.

How to Optimize The DOS-Mode

Plug And Play

Plug & Play DDC2B Feature

This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD. It allows the

monitor to inform the host system of its identity and, depending on the level of DDC used, communicate additional

information about its display capabilities.

The DDC2B is a bi-directional data channel based on the I²C protocol. The host can request EDID information over

the DDC2B channel.

This monitor will appear to be non-functional if there is no video input signal. In order for this monitor to

operate properly, there must be a video input signal.

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association (VESA)

and/or the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees

(NUTEK). This feature is designed to conserve electrical energy by reducing power consumption when there is no

video-input signal present. When there is no video input signals this monitor, following a time-out period, will

automatically switch to an OFF mode. This reduces the monitor's internal power supply consumption. After the video

input signal is restored, full power is restored and the display is automatically redrawn. The appearance is similar to

a "Screen Saver" feature except the display is completely off. Pressing a key on the keyboard, or clicking the mouse

restores the display.

Using the Right Power Cord

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is UL listed

and CSA labeled. The voltage rating for the power cord shall be 125 volts AC.

Supplied with units intended for connection to power outlet of personal computer: Please use a cord set consisting of

a minimum No. 18 AWG, type SJT or SVT three conductors flexible cord. One end terminates with a grounding type

attachment plug, rated 10A, 250V, and CEE-22 male configuration. The other end terminates with a molded-on type

connector body, rated 10A, 250V, having standard CEE-22 female configuration.

Please note that power supply cord needs to use VDE 0602, 0625, 0821 approval power cord in European counties.

Enter into the factory mode:

Turn off the power, press the “e-color” and turn the power on. The factory OSD will be at the left top of the panel.
