You can calculate more detailed screen dimension from the screen diagonal.
Screen width (SW) and screen height (SH)

SW (m) = SD (") x 0.0203 SH (m) = SD (") x 0.0152

Minimum distance (LW) and maximum distance (LT)

PT-LB80NTU: LW (m) = 0.0296 x SD (") - 0.039 LT (m) = 0.0358 x SD (") - 0.047

prise de courant comme mesure de sécurité avant
d'effectuer tout nettoyage.

Sinon cela peut causer des chocs électriques.

Si la lampe s'est cassée, ventiler immédiatement la
pièce. Ne pas toucher ni approcher le visage des
morceaux cassés.

Le non respect de cette consigne peut entraîner

l'absorption du gaz par l'utilisateur. Ce gaz se dégage
lorsque la lampe est cassée et il contient presque
autant de mercure qu'une lampe fluorescente, de
plus les morceaux cassés peuvent provoquer des
blessures.

Si vous pensez avoir inhalé du gaz ou que du gaz a

pénétré dans votre bouche ou dans vos yeux, con­tactez un médecin immédiatement.

S'adresser au revendeur pour le remplacement de la

lampe et l'inspection de l'intérieur du projecteur.
