Lamp replacement (continued)

4. Pull up the handle (g), and then pull out the lamp unit (h) by the

handle.

5. Remove the lamp attachment unit.

• Pull the lamp unit out of the projector slowly. If it is pulled out

quickly, the lamp may break, scattering glass fragments.

• Do not spill liquid on the removed lamp unit or do not place it

near any flammable object or where children can reach to pre-

vent injuries or fire.

When the projector is mounted to the ceiling:

Confirm that the lamp unit (h) is securely held inside the lamp dis-

posable bag of the lamp attachment unit. And then loosen the screw

(f) that come with the lamp attachment unit. Then remove the lamp

attachment unit.

6. Load a new lamp unit securely into the projector in the right orien-

tation.

7. Tighten up the screw (c) using a Phillips screwdriver (+) to secure

the lamp cover (d).

• Make sure that the lamp cover is secured firmly. Otherwise, the

POWER indicator flashes red and green, disallowing the projec-

tor to be powered on.

Reset of the lamp operation time

Plug in the power cord, and reset the lamp operation time by keep

pressing the W, X, and POWER buttons on the control panel at the

same time.

Important:

• Unless these three buttons are pressed at the same time, the lamp

operation time isn’t reset.

• Make sure that the STATUS indicator is lit twice and the lamp oper-

ation time is reset successfully.

• The projector doesn’t turn on if the lamp cover isn’t attached

securely.

• Be sure to reset the lamp operation time whenever you replace the

lamp.

• Do not reset the lamp operation time unless you replace the lamp.

Caution:

• The lamp is fragile. If it is broken, be careful not to cut yourself with

glass fragments.

• Contact your dealer for a new lamp.

Interval of lamp replacement

When the lamp shutdown notice is issued, the lamp replacement is

recommended even if the lamp is lit normally. Decrease in lumines-

cence and/or color brightness indicates that the lamp needs to be

replaced. When the lamp operation time exceeds the time elapsed

until the lamp shutdown notice

is issued, the indicator will blink alter-

nately green and red while the lamp is lit (while the lamp is not lit, the

indicator will blink red only) and the lamp replacement message will

appear on the screen for one minute every time the lamp is turned on.

When the lamp operation time exceeds the time elapsed until the

lamp shutdown warning

is issued, the replacement message (LAMP

EXCHANGE) will appear on the screen for one minute at fixed inter-

vals

thereafter.

When the lamp operation time exceeds the time elapsed

until the lamp shutdown

, the projector automatically

shuts off and can’t be used until the lamp is replaced

and the lamp operation time is reset.

The times above are when LAMP MODE of the INSTALLATION menu

is set to LOW. When it is set to STANDARD, this duration will be short-

ened.

These intervals vary depending on the lamp mode setting.

When LAMP MODE is set to STANDARD, the time elapsed until

the lamp shutdown will be shortened to 2000 hours.

Important:

• Do not open the lamp cover when the projector is set at a ceiling or

a high place. Lamp fragments may fall from the inside if the lamp

were broken.

Please contact your dealer when you need to replace the lamp

with a new one.

Caution:

• This projector uses a lamp that contains mer-

cury. Disposal of the lamp or the projector with

the lamp may be regulated due to environ-

mental considerations. For disposal or recy-

cling information, please contact your local

authorities or the Electronic Industries Alli-

ance: www.eiae.org. (For US only).
