Page 58: Replacing The Lamp Cartridge
Replacing the Lamp Cartridge • The lamp that is used as a light source in the projector has a limited service life. The rated service life of the lamp is about 1500 hours (when used in normal mode only). This could be shortened depending on conditions of use and other factors. - Page 59 Replacing the Lamp Cartridge Preparations: Turning the projector upside-down on top of a soft cloth, etc., so that it does not get scratched makes it easier to replace the lamp cartridge. Turn the projector right-side up after replacing the lamp cartridge.
- Page 60 After reaching the lamp service life, if the lamp is used for more than another 100 hours, it will not be possible to switch on the power. Should this happen, while the projector is in the standby mode, simultaneously holding down the projector’s SOURCE button and AUTO button for more than 5 seconds will clear the lamp timer.
