2.7 Instructions for use

1. The lamp becomes high temperature after turning off the projector with the power button. I f you touch the lamp, you may scald your finger. When you replace the lamp, wait for at least 45 minutes for the lamp to cool down.

2. Do not touch the lamp glass at any time. The lamp may explode due to improper handling, including the touching of the lamp glass.

3. Lamp lifetime may differ from lamp to lamp and according to the environment of use. There is no guarantee of the same lifetime for each lamp. Some lamps may fail or terminate their lifetime in a shorter period of time than other similar lamps.

4. A lamp may explode as a result of vibration, shock or degradation as a result of hours of use as its lifetime draws to an end. Risk of explosion may differ according to the environment or conditions in which the projector and lamp are being used.

5. Wear protective gloves and eyeglasses when fixing or detaching the lamp.

6. Faster on-off-cycles will damage the lamp and reduce lamp life. Wait at least for 5 minutes to turn off the projector after powering on.

7. Do not operate the lamp in proximity to paper, cloth, or other combustible material nor cover it with such materials. Otherwise it could cause a fire.

8. Do not operate the lamp in an atmosphere containing an inflammable substance, such as thinner . Otherwise it could cause a fire or explosion.

9. Thoroughly ventilate the area or the room when operating the lamp in an oxygen atmosphere (in the air). I f ozone is inhaled, it could cause headaches, nausea, dizziness, etc.

10. The inorganic mercury is involved in the lamp. I f the lamp bursts, the mercury inside the lamp will go out of the projector . Leave the area immediately if the lamp shatters while being operated and ventilate the area for at least 30 minutes in order to avoid the inhalation of mercury fumes. Otherwise it could be harmful to user’s health.

11. Dispose of the used lamp according to local regulations.

12. Ensure that screws are tightened properly. Screws not tightened fully may result in injury or accidents.

13. Since the lamp is made of glass, do not drop the unit and do not scratch the glass.

14. Do not reuse the old lamp. This could cause the lamp to explode.

15. Be sure to turn off the projector and unplug the AC power cord before replacing the lamp.

16. Do not use the projector with the lamp cover removed.

Disposal : For disposal of spent lamps, always consult federal, state, local and provincial hazardous waste disposal rules and regulations to ensure proper disposal.

Caution : This lamp emits ultra violet (UV) radiation and operates at high pressure. This lamp may only be used in enclosed fixtures that comply with UL1572. Due to the high luminous efficacy, the UV radiation which the lamp emits and the high pressure within the lamp, P-VI Pâ lamps may only be operated within enclosed, purpose-built housings.
