Notes and Precautions

•The Lamp time item in the Status display menu indicates the time of lamp use (as a rough guide). p.48

•It is recommended that the lamp be replaced after 2,000 hours of use. When [Lamp time] reaches 2,000 hours, the icon and a message will appear with a beep sound. (After 2,000 hours, they will appear when the power is on at the first time every 100 hours.) This display disappears when you press the button.

•Attach the outer lamp cover correctly so that it is not loose. If it is not attached correctly, the projector may fail to be powered on or the lamp may fail to come on.

•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

This projector’s lamps contain trace amounts of environmentally harmful inorganic mercury. Be careful not to break used lamps, and dispose of them in accordance with local regulations.

Lens and main unit cleaning

WARNING

•Request cleaning and maintenance of a ceiling-mounted unit from your projector dealership. Attempting to clean/replace the lamp at a high site by yourself may cause you to fall down, thus resulting in injury.

■Lens cleaning

• Clean the lens with a commercially available blower and/or lens cleaner.

• The lens is easily scratched, so do not rub it with hard objects, or strike it.

■ Main unit cleaning

•Clean the main unit after unplugging the power cord.

•Wipe dirt off the main unit gently with a soft cloth.

• Do not wipe the main unit with a damp cloth. Doing so may allow water to get inside, resulting in an electric shock or failure.

• Do not use benzene, thinner and the like as they may deform or discolor the unit or damage the paint surface.

•When using a chemically treated cloth, follow the precautions included with the cloth.
