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 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.

z Slots and openings in the back and bottom of the cabinet area provided for ventilation. To ensure

reliable operation of the monitor an d to protect it from o verheating, 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 book case or cabi net 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 o utlet, or use an adapter to ground the appliance safely. Do not defeat the safety purpose of the grounded plug.

z 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.

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 licens e

SPECIAL NOTES ON LCD MONITORS

The following symptoms are normal with LCD monitor and do not indicate a problem.

NOTES

z 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.

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

z 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.

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 communicati on channel is defined in two levels, DDC2B. The DDC2B is a bi-directional data channel based on the I information over the DDC2B channel.

C protocol. The host can request EDID

Page 27

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 A WG, 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 approv al power cord in European counties.

“Auto” means the PC writing automatically. “Erase” means procedure erased the former bios of monitor.

When write Acer model bios, if two files used, set up the file properties as fellow:

1. Within 64K option, choose the bios file without “ext”;

2. Within 64K~~96K option, choose the bios file with “ext”;

3. Then choose “Both”;

4. Then choose “Auto”;

5. Click , go to write.

Notice: The distinction between ”64K” and “64-96K” is from BIOS file name. Such as: 64K: WDZV-W1_SAM_FW_V100_0x90_061907 64-96K: WDZV-W1_SAM_FW_V100_0x89_Extend_061907

Page 40

Before writing, please make sure that the monitor must be turned on. During writing, it can’t work if power cutting off, and VGA cord falling off After writing OK, it will display “CRC OK”.

Notices:

When writing was interrupted, the message will show “MCU link error”. Analysis: Check:

1. Whether the connection to writing card and writing cord are ok and all tools are ok?

2. Whether the monitor is “on” state (it can’t into factory state, please retry again)

3. Whether the cord connections is ok?

4. Whether PC LPL is ok?

5. Whether the main board of Monitor is good?

(After checking above items, you should search for more supports from related dept if it has not worked yet

Warning!!

Don’t choose the error position of BIOS file between “64K” and “64~~94”. If do, it works but
