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

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

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.

PRECAUTIONS
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
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.
zSlots 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.
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. 3.5A.
zThe wall socket shall be installed near the equipment and shall be easily accessible.
zFor 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
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 in 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.

(2) Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression and figure below.
Contrast Ratio (CR) = L255 / L0
L255:Luminance of gray level 255
L 0: Luminance of gray level 0
CR = CR (1)
CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note (5).

Measurement System Setup:
The LCD module should be stabilizedat given temperature for (20) minutes to avoid abrupt
temperature change during measuring. In order to stabilize the luminance, the measurement
should be executed after lighting Backlight for (20) minutes in a windless room.
nFor TCO03/TCO99 CCT test condition requirement, the brightness and contrast setting on
OSD shall be adjusted to meet 125 nit.
