EUT Type: 24” LCD Monitor FCC ID: BEJL245WHS Test Report No.: GETEC-E3-07-045 FCC Class B Certification APPENDIX H : USER’S MANUAL Make sure to read the Important Precautionsbefore using the product. Keep the User's Guide(CD) in an accessible place for furture reference. See the label attached on the product and give the information to your dealer when you ask for service. L245WH User’s Guide A1 This unit has been engineered and manufactured to ensure your personal safety, however improper use may result in potential eletrical shock or fire hazards. In order to allow the proper operation of all safeguards incorporated in this display, observe the following basic rules for its installation, use, and servicing. On Safety Use only the power cord supplied with the unit. In case you use another power cord, make sure that it is certified by the applicable national standards if not being provided by the supplier. If the power cable is faulty in any way, please contact the manufacturer or the nearest authorized repair service provider for a replacement. The power supply cord is used as the main disconnection device. Ensure that the socket-outlet is easily accessible after installation. Operate the display only from a power source indicated in the specifications of this manual or listed on the display. If you are not sure what type of power supply you have in your home, consult with your dealer. Overloaded AC outlets and extension cords are dangerous. So are frayed power cords and broken plugs. They may result in a shock or fire hazard. Call your service technician for replacement. Do not Open the Display. There are no user serviceable components inside. There are Dangerous High Voltages inside, even when the power is OFF. Contact your dealer if the display is not operating properly. To Avoid Personal Injury : Do not place the display on a sloping shelf unless properly secured. Use only a stand recommended by the manufacturer. To Prevent Fire or Hazards: Always turn the display OFF if you leave the room for more than a short period of time. Never leave the display ON when leaving the house. Keep children from dropping or pushing objects into the display's cabinet openings. Some internal parts carry hazardous voltages. Do not add accessories that have not been designed for this display. During a lightning storm or when the display is to be left unattended for an extended period of time, unplug it from the wall outlet. Important Precautions A2 Important Precautions On Installation Do not allow anything to rest upon or roll over the power cord, and do not place the display where the power cord is subject to damage. Do not use this display near water such as near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool. Displays are provided with ventilation openings in the cabinet to allow the release of heat generated during operation. If these openings are blocked, built-up heat can cause failures which may result in a fire hazard. Therefore, NEVER: Block the bottom ventilation slots by placing the display on a bed, sofa, rug, etc. Place the display in a built-in enclosure unless proper ventilation is provided. Cover the openings with cloth or other material. Place the display near or over a radiator or heat source. Do not rub or strike the Active Matrix LCD with anything hard as this may scratch, mar, or damage the Active Matrix LCD permanently. Do not press the LCD screen with your finger for a long time as this may cause some afterimages. Some dot defects may appear as Red, Green or Blue spots on the screen. However, this will have no impact or effect on the display performance. If possible, use the recommended resolution to obtain the best image quality for your LCD display. If used under any mode except the recommended resolution, some scaled or processed images may appear on the screen. However, this is characteristic of the fixed-resolution LCD panel. On Cleaning Unplug the display before cleaning the face of the display screen. Use a slightly damp (not wet) cloth. Do not use an aerosol directly on the display screen because over-spraying may cause electrical shock. On Repacking Do not throw away the carton and packing materials. They make an ideal container in which to transport the unit. When shipping the unit to another location, repack it in its original material. On Disposal The fluorescent lamp used in this product contains a small amount of mercury. Do not dispose of this product with general household waste. Disposal of this product must be carried out in accordance to the regulations of your local authority. Connecting the Display A3 Before setting up the monitor, ensure that the power to the monitor, the computer system, and other attached devices is turned off. Connecting the stand base or Removing the stand base 1. Place the monitor with its front facing downward on a cushion or soft cloth. The tape and locking pin may only be removed from those monitors equipped with a standing base when the base is pulled up. Otherwise, you may be injured by the protruding sections of the stand. Warning : 2.Align the hooks on the Stand Body with the matching slots in the Stand Base. 3. Insert the hooks into slots. Slot Hook Stand Base A4 Connecting the Display Important This illustration depicts the general model of connection. Your monitor may differ from the items shown in the picture. Do not carry the product upside down holding only the stand base. The product may fall and get damaged or injure your foot. 4.Attach the monitor to the Stand Base by turning the screw to the right. Screw : Turn the screw by using the screw handle. 5.Lift and turn the monitor to face towards the front after the connection is made to the female part of the cable you're attaching. 6.Take the screw out by turning to the left to separate the monitor and Stand Base. A5 Connecting the Display Before setting up the monitor, ensure that the power to the monitor, the computer system, an…
