Lampun vaihtaminen
Projektorin lamppu on kuluva osa. Parhaan katselunautinnon saavuttamiseksi vaihda lamppu käyttöajan loputtua. Näet lampun käyttöajan projektorin informaationäytöstä (INFO 
Käytä suositeltua lamppua vaihdettaessa. Lampun tekniset tiedot on esitetty käyttöoppaassa. Käytä uusimisessa samaa mallia kuin projektorin mukana on toimitettu.
Varmista ennen lampun vaihtamista, että virtajohto on irrotettu.
Vaikka virtajohto on irrotettu, lamppu saattaa olla kuuma. Anna lampun jäähtyä vähintään yksi tunti ennen sen vaihtamista.
Lamppu sijaitsee projektorin vasemmassa takaosassa.
Ennen projektorin kääntämistä lampun vaihtoa varten, suojaa projektori pehmeällä liinalla tasaisella alustalla.
Älä jätä vanhaa lamppua syttyvän materiaalin lähelle tai lasten saataville. On olemassa palon tai loukkaantumisen vaara.
