Lamp replacement

A lamp is consumable supplies. If used for extended periods, images will appear dark, and the lamp could burn out. This is characteristic of a lamp, and is not malfunction. (The lifetime of the lamp depends on conditions of use.) If this happens, replace it with a new one.

CAUTION

•Request cleaning and maintenance of a ceiling-mounted unit from your projector dealership.

•When replacing, always use lamp “TLPLW2” (sold separately).

•If you have been using the projector, the lamp will be very hot, and may cause burn injuries.

Wait for the lamp to cool (for longer than 1 hour) before replacing it.

•If the lamp should break, please handle with care to avoid injury due to broken pieces and contact your dealer for repair service.

Notes and Precautions

•Press thebutton 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.)
