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 an 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. Dangerously high voltages are
present inside the monitor. Do not open the cabinet. Refer servicing to qualified personnel only.

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, use 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.
zUnplug 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. 3.5A.
z The wall socket shall be installed near the equipment and shall be easily accessible.
z 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 on 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.

• Do not install the monitor in a location near heat sources such as radiators or air ducts, or in a place subject to
direct sunlight, or excessive dust or mechanical vibration or shock.
• Save the original shipping carton and packing materials, as they will come in handy if you ever have to ship
your monitor.
• For maximum protection, repackage your monitor as it was originally packed at the factory.
• To keep the monitor looking new, periodically clean it with a soft cloth. Stubborn stains may be removed with a
cloth lightly dampened with a mild detergent solution. Never use strong solvents such as thinner, benzene, or
abrasive cleaners, since these will damage the cabinet. As a safety precaution, always unplug the monitor
before cleaning it.
