Contact a qualified service technician or your retailer. • Before using the product, make sure all cables are correctly connected and the power cables are not damaged. If you detect any damage, contact your dealer immediately. • Slots and openings on the back or top of the cabinet are provided for ventilation. Do not block these slots.

Clean the monitor surface with a lint-free, non-abrasive cloth. Stubborn stains may be removed with a cloth dampened with mild cleaner. • Avoid using a cleaner containing alcohol or acetone. Use a cleaner intended for use with the LCD. Never spray cleaner directly on the screen, as it may drip inside the monitor and cause an electric shock. The following symptoms are normal with the monitor: • The screen may flicker during the initial use due to the nature of the fluorescent light. Turn off the Power Switch and turn it on again to make sure that the flicker disappears. • You may find slightly uneven brightness on the screen depending on the desktop pattern you use. • When the same image is displayed for hours, an afterimage of the previous screen may remain after switching the image. The screen will recover slowly or you can turn off the Power Switch for hours. • When the screen becomes black or flashes, or cannot work anymore, contact your dealer or service center to fix it.
