Replacing the lamp
•  To reduce the risk of electrical shock, always turn the projector off and disconnect the power cable 
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.
•  To reduce the risk of injuries to fingers and/or compromising image quality by touching the lens, do 
not touch the empty lamp compartment when the lamp is removed.
•  This lamp contains mercury. Consult your local hazardous waste regulations to dispose of this lamp in 
a proper manner.
•  To assure optimal performance from the projector, it is recommended that you purchase a qualified 
projector lamp for lamp replacement.
•  Ensure good ventilation when handling broken lamps. We recommend that you use respirators, safety 
glasses, goggles or face shield and wear protective clothing such as gloves. 
1. Turn the power off and disconnect the projector from the power outlet. If the lamp is hot, 
avoid burns by waiting for approximately 45 minutes until the lamp has cooled.
2. Loosen the screws that secure the lamp cover on the 
top of the projector until the lamp cover loosens.
3. Push the lamp cover open.
4. Remove the lamp cover from the projector.
5. Confirm a position of the lamp protection film to put a 
new film on the same position later, then remove and 
dispose of the lamp protection film.
•  Do not turn the power on with the lamp cover removed.
•  Do not insert your fingers between the lamp and the 
projector as the sharp edges inside the projector may 
cause injuries.

removed. If you touch the optical components inside, it 
could cause color unevenness and distortion of the 
projected images.

(replacement lamp: 
PK-L3715U).
10. Tighten the screw that secures the lamp.
11. Ensure the handle is fully laid flat and locked in place.
