Replacing the Lamp Projector lamps have a finite life. Replace the lamp when: A warning message "Lamp is approaching the end of its useful life in full power operation. Replacement Suggested!" appears on the screen. The image becomes darker and hues become weaker after a lamp has been for a long period of time. The projector lamp LED indicator turns into red. Refer to section titled "Indicator Messages" for further details. The lamp becomes high temperature after turning off the projector with the power button. If 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. Do not touch the lamp glass at any time. The lamp may explode due to improper handling, including the touching of the lamp glass. 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. 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. Wear protective gloves and eyeglasses when fixing or detaching the lamp. 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. 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. Do not operate the lamp in an atmosphere containing an inflammable substance, such as thinner. Otherwise it could cause a fire or explosion. Thoroughly ventilate the area or the room when operating the lamp in an oxygen atmosphere (in the air). If ozone is inhaled, it could cause headaches, nausea, dizziness, etc. The inorganic mercury is involved in the lamp. If 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. ViewSonic PJ558D 28

Replacing the Lamp
Projector lamps have a finite life. Replace the lamp when:
A warn±ng message “Lamp ±s approach±ng the end of ±ts useful l±fe ±n full power
operat±on. Replacement Suggested!” appears on the screen.
The ±mage becomes darker and hues become weaker after a lamp has been for
a long per±od of t±me.
The projector lamp LED ±nd±cator turns ±nto red. Refer to sect±on t±tled “Ind±cator
Messages” for further deta±ls.
The lamp becomes h±gh temperature after turn±ng off the projector w±th the
power button. If you touch the lamp, you may scald your finger. When you
replace the lamp, wa±t for at least 45 m±nutes for the lamp to cool down.
Do not touch the lamp glass at any t±me. The lamp may explode due to ±mproper
handl±ng, ±nclud±ng the touch±ng of the lamp glass.
Lamp l±fet±me may d±ffer from lamp to lamp and accord±ng to the env±ronment
of use. There ±s no guarantee of the same l±fet±me for each lamp. Some lamps
may fa±l or term±nate the±r l±fet±me ±n a shorter per±od of t±me than other s±m±lar
lamps.
A lamp may explode as a result of v±brat±on, shock or degradat±on as a result
of hours of use as ±ts l±fet±me draws to an end. R±sk of explos±on may d±ffer
accord±ng to the env±ronment or cond±t±ons ±n wh±ch the projector and lamp are
be±ng used.
Wear protective gloves and eyeglasses when fixing or detaching the lamp.
Faster on-off-cycles w±ll damage the lamp and reduce lamp l±fe. Wa±t at least
for 5 m±nutes to turn off the projector after power±ng on.
Do not operate the lamp ±n prox±m±ty to paper, cloth, or other combust±ble
material nor cover it with such materials. Otherwise it could cause a fire.
Do not operate the lamp in an atmosphere containing an inflammable substance,
such as thinner. Otherwise it could cause a fire or explosion.
Thoroughly vent±late the area or the room when operat±ng the lamp ±n an oxygen
atmosphere (±n the a±r). If ozone ±s ±nhaled, ±t could cause headaches, nausea,
d±zz±ness, etc.
The ±norgan±c mercury ±s ±nvolved ±n the lamp. If the lamp bursts, the mercury
±ns±de the lamp w±ll go out of the projector. Leave the area ±mmed±ately ±f the
lamp shatters wh±le be±ng operated and vent±late the area for at least 30 m±nutes
±n order to avo±d the ±nhalat±on of mercury fumes. Otherw±se ±t could be harmful
to user’s health.
