Notes and Precautions
• Press the button twice to display (a rough guide) of the time of use from the Lamp
time item on the Status display menu. p.32
• As a rule of thumb, it is recommended that the lamp should be replaced after 1,500
hours of use. When Lamp time reaches 1,500 hours, the icon and a message will
appear. When any operation is performed, the message disappears.
• Attach the lamp cover correctly so that it is not loose. If it is not attached correctly, the
lamp may fail to come on p.65 , and the lamp’s lifetime may be shortened.
• Always replace the lamp with a new one.
• The lamp is made out of glass. Do not touch the glass surface with your bare hands,
bang it, or scratch it. (Dirt, jolts, scratches and the like could break the lamp.)
Used Lamps

and contact your dealer for repair service.
