personnel/channel to provide you with further technical details.

2. please not 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

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

guidelines for energy efficiency.

WARNING:

To prevent fire or chock hazard, do not expose the monitor to rain or moisture. Dangerously high voltages are

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



- 6 -

PRECAUTIONS Do not use the monitor near water, e.g. near a bathtub, washbowl, kitchen sink, laundry tub,

Swimming pool or in a wet basement.

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 manufacture or

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

manufacture and follow the kit instructions.

Slots and openings in the back and bottom of the cabinet area 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.

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.

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.

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.

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

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.

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.

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

configured receptacles marked between 100-240V AC, Min. 3.5A.

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

For use only with the attached power adapter (output 12V DC) which have UL,CSA listed license

SPECIAL NOTES ON LCD MONITORS The following symptoms are normal with LCD monitor and do not indicate a problem.

NOTES 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.

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

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.

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 communication channel is defined in two levels, DDC2B.

The DDC2Bis a bidirectional 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 signal 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. The display is restored by pressing a key

on the keyboard, or clicking the mouse.

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 volt 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,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 card needs to use VDE 0602, 0625, 0821 approval power cord in European

counties.

Chapter 3 Machine Disassembly and Replacement This chapter contains step-by-step procedures on how to assemble the monitor for maintenance and trouble shooting NOTE : 1. The screws for the different components vary in size. During the disassembly process, group the

screws with the corresponding to avoid mismatch when putting back the components.

2. Note : The monitor surface is susceptible to scratching! Therefore, lay the monitor on a soft surface when mounting or removing the base.

3. Wear gloves.
