About lamp

The product’s light source is a mercury lamp that lights at increased internal pressure. Be sure to fully understand the following characteristics of the lamp and handle it with extreme care.

• The lamp may explode with a loud noise due to impact or deterioration, or fail to light at

the expiration of its life.

• How long it takes before the lamp explodes or the life expires may vary greatly by lamp.

Some may explode shortly after first use. (Free replacement is available if the lamp

explodes within the warranty period. Contact the dealer from whom you purchased the

product in such a case.)

• Explosion is likely to happen if the lamp is used after the replacement period has elapsed.

• When the lamp explodes, the broken pieces of glass may get inside the product or be

released outside from the openings for ventilation.

• When the lamp explodes, a slight amount of mercury gas enclosed in the lamp along

with glass dust may be released from the openings for ventilation.

■ Immediately replace the lamp when a sign appears on the screen.

• When the replacement time approaches, a message will appear on the screen.

• The risk of explosion will increase if the lamp is continuously used without being replaced.

• Frequently check the used hours and prepare spares when the replacement time

approaches. (Refer to “Status display”. p.33 )

	pieces with care to avoid injury and contact your dealer for repair service.

	completely ventilate the room. Then, thoroughly clean the area around the projector and
	discard any edible items placed in that area.

	eyes or you breathe it.

Lamp replacement

A lamp is consumable supplies. If used for extended periods, images will appear dark, and the lamp could burn out. This is characteristic of a lamp, and is not malfunction. (The lifetime of the lamp depends on condition of use.) If this happens, replace it with a new one.

WARNING

•If the projector is mounted on a ceiling, request a lamp replacement from your projector dealership.

•When replacing, always use lamp “TLPLV4” (sold separately).

CAUTION

•If you have been using the projector, the lamp will be very hot, and may cause burn injuries. Wait for the lamp to cool (for longer than 1 hour) before replacing it.

•If the lamp should break, please handle with care to avoid injury due to broken pieces and contact your dealer for repair service.

5 Mount the new lamp.

Align the orientation, press down until the bottom is reached, and lock in place using the two lamp locking screws.

6 Replace the lamp cover.

Align the cover, and press it in, then tighten the screws loosened in step 3 until the lamp cover is no longer loose.

7 Reset the lamp timer.

See the lamp’s manual for instructions on resetting the lamp timer.

Notes and Precautions

•It is recommended that the lamp be replaced after 3,000 hours of use. When Lamp time reaches 3,000 hours, the icon and a message will appear. This display disappears when you press button.

•Attach the lamp cover correctly so that it is not loose. If it is not attached correctly, the lamp may fail to come on p.41 , and the lamp’s lifetime may be shortened.
