LENOVO THINKVISION L2251P (01) PDF DOCUMENT

The power cord is designed for use with your LENOVO THINKVISION L2251P monitor. To use a different cord, use only a power source and connection compatible with this monitor.

WARNING: Always connect your monitor, the computer, and other equipment to a grounded (earthed) power outlet. To reduce the risk of electric shock or damage to your equipment, do not disable the power cord grounding feature. The grounding plug is an important safety feature.

WARNING: For your safety, be sure that the grounded power outlet you plug the power cord into is easily accessible to the operator and located as close to the equipment as possible. To disconnect power from the equipment, unplug the power cord from the power outlet by grasping the plug firmly. Never pull on the cord.

CAUTION: To protect your monitor, as well as your computer, connect all power cords for your computer and its peripheral devices (such as a monitor, printer, or scanner) to a surge protection device such as a power strip with surge protection or uninterruptible power supply (UPS). Not all power strips provide surge protection; the power strips must be specifically labeled as having this ability. Use a power strip whose manufacturer offers a damage replacement policy, so you can replace your equipment if surge protection fails.

CAUTION: A certified power supply cord has to be used with this equipment. The relevant national installation and/or equipment regulations shall be considered. A certified power supply cord not lighter than ordinary polyvinyl chloride flexible cord according to IEC 60227 (designation H05VV-F 3G 0.75mm² or H05VVH2-F2 3G 0.75mm²) shall be used. Alternative a flexible cord be of synthetic rubber.

Use only a power source and connection compatible with this monitor, as indicated on the label/back plate of the monitor.

Be sure the total ampere rating of the products connected to the outlet does not exceed the current rating of the electrical outlet, and the total ampere rating of the products connected to the power cord does not exceed the rating of the power cord. Look on the power label to determine the ampere rating (Amps or A) for each device.

Install your monitor near a power outlet that you can easily reach. Disconnect the monitor by grasping the plug firmly and pulling it from the outlet. Never disconnect the monitor by pulling the cord.

Do not allow anything to rest on the power cord. Do not walk on the cord.

While using VESA mount application, the AC Inlet must face to down side. Do not face any other position.

The monitor is a high-quality optical device that requires special care when cleaning. To clean the monitor, follow these steps:

1. Turn off the computer and the monitor.

2. Unplug your monitor from the power outlet before cleaning.

CAUTION: Do not use benzene, thinner, ammonia, or any volatile substance to clean the monitor screen or cabinet. These chemicals may damage the monitor. Do not use liquid or aerosol cleaners. Never use water to clean an LCD screen.

3. Wipe the screen with a dry, soft, clean cloth. If the screen requires additional cleaning, use an antistatic screen cleaner.

4. Dust the monitor housing. Use a damp cloth to clean the cabinet. If the cabinet requires additional cleaning, use a clean cloth dampened with isopropyl alcohol.

5. Plug in the monitor.

6. Turn on the monitor and the computer.

To enhance the performance and extend the life of your monitor:

Do not open your monitor cabinet or attempt to service this product yourself.

Adjust only those controls that are described in the operating instructions.

Turn your monitor off when not in use. You can substantially increase the life expectancy of the monitor by using a screen saver program and turning off the monitor when not in use.

Keep your monitor in a well-ventilated area, away from excessive light, heat, or moisture.

Slots and openings in the cabinet are provided for ventilation. These openings must not be blocked or covered.

Never push objects of any kind into cabinet slots or other openings.

Unplug the monitor from the power outlet before cleaning. Do not use liquid cleaners or aerosol cleaners.

Good ergonomic practice is important to get the most from your computer and to avoid discomfort. Arrange your workplace and the equipment you use to suit your individual needs and the kind of work that you perform.

Positioning and viewing your monitor:

Viewing distance: Optimal viewing distances for monitors range from approximately 510mm to 760mm (20 in to 30 in) and can vary depending on ambient light and time of day. Use a viewing distance that is most comfortable for you.

Monitor height: Position the monitor so your head and neck are in a comfortable and neutral (vertical, or upright) position. A general guideline is to position the monitor such that the top of the screen is at or slightly below your eye-height when you are comfortably seated.

Tilt: Adjust the tilt of your monitor to optimize the appearance of the screen content and to accommodate your preferred head and neck posture.

General location: Position your monitor to avoid glare or reflections on the screen from overhead lighting or nearby windows.

Good posture starts with equipment setup: The layout of your work area and the setup of your computer equipment have a large effect on your posture. Be sure to optimize the position and orientation of your equipment.

Minor changes in posture can help avoid discomfort: The longer you sit and work with your computer, the more important it is to observe your working posture. Avoid assuming any one posture for an extended period. Periodically make minor modifications in your posture to help deter any discomforts that might arise.

Short, periodic breaks help ensure healthy computing: Because computing is primarily a static activity, it is particularly important to take short breaks from your work. Periodically, stand up from your work area, stretch, walk for a drink of water, or otherwise take a short break from using your computer.

The display modes shown below have been optimized at the factory for the LENOVO THINKVISION L2251P.

Power management is invoked when the computer recognizes that you have not used your mouse or keyboard for a user-definable period. For optimal performance, switch off your monitor at the end of each working day, or whenever you expect to leave it unused for long periods.

Before rotating the LENOVO THINKVISION L2251P monitor, you should set up your computer to rotate the image. This may require special rotation software or a video graphics driver that allows image rotation. Check the Graphic Properties setting on your computer to see if this feature is available.

Try these steps to check if image rotation is available on your computer:

1. Right-click on the desktop and click Properties.

2. Select the Settings tab and click Advanced.

3. If you have an ATI graphics card, select the Rotation tab and set the preferred rotation. If you have nVidia, click the nVidia tab, in the left-hand column select NVRotate, and then select the preferred rotation. If you have Intel, select the Intel graphics tab, click Graphic Properties, select the Rotation tab, and then set the preferred rotation.

Check with the manufacturer of your computer to see if graphic drivers with image rotation can be downloaded from their support website.

Be sure to turn off the power before you perform any maintenance on the monitor.

Do not:

• Apply water or liquid directly to your monitor.

• Use solvents or abrasives.

• Use flammable cleaning materials to clean your monitor or any other electrical equipment.

• Touch the screen area of your monitor with sharp or abrasive items. This type of contact may cause permanent damage to your screen.

• Use any cleaner which contains an anti-static solution or similar additives. This may harm the coating of the screen area.

Do:

• Lightly dampen a soft cloth with water and use this to gently wipe the covers and the screen.

• Remove grease or finger marks with a damp cloth and a little mild detergent.

After placing the monitor face down on a clean surface or soft cloth, remove the four screws from the stand to remove it from the monitor.
