CLEANING AND MAINTENANCE (Continued)
• Lamp life differs according to the lamp and the environment it is used in. The lamp may explode immediately after starting use.
• When the lamp reaches the end of its service life, the image becomes dark and the colors lose their vividness. When this happens, change
the lamp unit.
• Replace with a new lamp unit when the replace lamp message appears. The old lamp may explode if it continues to be used.
• After removing the old lamp unit, handle with care to avoid breakage. Dispose of used lamp units as industrial waste and comply with
governmental regulations or environmental public institution's rules that apply in your country/area.
• Be sure to initialize the lamp timer after changing the lamp unit.
• When replacing the lamp unit, insert it securely. Otherwise, it may damage.
