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 cased, please
contact your regional offices or the responsible personnel/channel to provide you with further technical details.
2. Please not WHEN ORDER 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 PROVIEDERS, 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
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. User 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 following the kit
instructions.
Slots and openings in the back and bottom of the cabinet are provide 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.
SPECIAL NOTES ON LCD MONITORS
The following symptoms are normal with LCD monitor and do not indicated 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.
