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.

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.
Precautions
http://www.wjel.net
5
zDo not use the monitor near water, e.g. near a bathtub, washbowl, kitchen sink, laundry tub, swimming pool or in
a wet basement.
zDo 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.
zSlots 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.
zThe 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.
zThe 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.
zDo not overload power strips and extension cords. Overloading can result in fire or electric shock.
zNever 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.
zDo 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
zTo ensure satisfactory operation, use the monitor only with UL listed computers which have appropriate
configured receptacles marked between 100 - 240V AC, Min. 5A.
zThe 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
zDue 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.
zYou may find slightly uneven brightness on the screen depending on the desktop pattern you use.
zThe 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.
zDue 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.

Installation
To make it easier to connect the right plug into the right connector, Packard Bell has introduced Colour Coding.
Each connector has its own icon with its own colour. Please make sure to always put a plug into a connector with
corresponding icon and colour.
Make sure your system and LCD monitor power are OFF.
• If your computer is equipped with a VGA port, connect one of the VGA cable plugs to the VGA port on your
computer's rear panel and the other to the connector on the rear of the monitor. According to PC99 requirements,
the VGA plug and connector should be coloured blue. The VGA interface allows your computer to output analog
signals.
The monitor is automatically configured to match the PC video settings with maximum SXGA resolution.
