Lamp Replacement Procedure - Canon 4K500ST User Manual

Before replacing the lamp, always turn off the projector, unplug it after
the cooling fan stops, and wait at least one hour. Do not touch the
lamp immediately after turning the projector off. It is very hot initially
and poses a risk of burns.
• Be sure to use the specified lamp.
• Contact the Canon Customer Support Center for further information.
This can also be purchased from the Canon website.
• Do not touch the inner glass surface when you replace the lamp.
Doing so may cause deterioration to the projector's performance.
• Handle lamps with care. Impact or abrasion may cause lamps to
rupture while they are in use. If a lamp ruptures, contact the Canon
Customer Support Center and follow the instructions in
"Precautions when replacing lamps that stop working" (P15).
• When replacing the lamp, do not remove any screws other than
those specified.
