Maintenance Care of the projector Your projector needs little maintenance. The only thing you need to do on a regular basis is to keep the lens clean. Never remove any parts of the projector except the lamp. Contact your dealer if other parts need replacing. Cleaning the lens Clean the lens whenever you notice dirt or dust on the surface. • • Use a canister of compressed air to remove dust.
Calculation of lamp hour When the projector is in operation, the duration (by hours) of lamp usage is automatically calculated by the built-in timer. The method of calculating the equivalent lamp hour is as follows: Total (equivalent) lamp hour = hours used in Economic mode + hours used in normal mode See "Economic Mode (Off)" on page 43 for more information on Economic mode. The lamp hour in Economic mode is calculated as 2/3 of that in normal mode.
Replacing the lamp • To reduce the risk of electrical shock, always turn the projector off and disconnect the power cord before changing the lamp. • To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes before replacing the lamp. To reduce the risk of injuries to fingers and damage to internal components, use caution when removing lamp glass that has shattered into sharp pieces.
• Pulling it too quickly may cause the lamp to break and scatter broken glass in the projector. • Do not place the lamp in locations where water might splash on it, children can reach it, or near flammable materials. • Do not insert your hands into the projector after the lamp is removed. If you touch the optical components inside, it could cause color unevenness and distortion of the projected images. Step 7. Insert a new lamp. Ensure the handle is fully laid flat and locked in place.
