nWhen to replace the lamp unit
The lamp unit is a consumable component. Brightness decreases according to duration of usage, so periodical
replacement of the lamp unit is necessary. When the projection lamp of the projector reaches its end of life, the
lamp replacement icon appears on the screen and <LAMP> indicator lights yellow. Replace the lamp with a new
one promptly.

The message is displayed for 10 seconds. If
you press any button within the 10 seconds,
the message disappears.
Lights in yellow (even in stand-by
mode).
Over 3200 hours*
If the power is turned on without replacing
the lamp, the power automatically turns off

Maintenance
The LAMP indicator will light yellow when the lamp runtime (Corresponding value) reaches 3,000 hours. This is to
indicate that lamp replacement is required. The lamp runtime is calculated by using the below expression.
Lamp runtime (Corresponding value) = Tnormal + Teco x 0.75
Tnormal : used time in the Normal and Auto mode
Teco : used time in the Eco1 and Eco2 mode
You can check the lamp runtime following to the below procedure.
1Press and hold the button on the projector or the POWER ON button on the remote control for more than 20
seconds.
2 The projector used time and lamp runtime will be displayed on the screen briefly as follows.

Cleaning
Cleaning the projection lens
Unplug the AC power cord before cleaning.
Gently wipe the projector body with a soft dry cleaning cloth. When the cabinet
is heavily soiled, use a small amount of mild detergent and finish with a soft dry
cleaning cloth. Avoid using an excessive amount of cleaner. Abrasive cleaners,
solvents or other harsh chemicals might scratch the surface of the cabinet.
When the projector is not in use, put the projector in an appropriate carrying
case to protect it from dust and scratches.
Cleaning the projector cabinet
Cleaning with air spray
Remove the cabinet top following to “Mechanical Disassembly”. Clean up the LCD panel and polarizing plate by using
the air spray from the cabinet top opening.
Caution:
Use a commercial (inert gas) air spray designed for cleaning camera and computer equipment. Use a resin-based
nozzle only. Be very careful not to damage optical parts with the nozzle tip. Never use any kind of cleanser on the unit.
Also, never use abrasive materials on the unit as this may cause irreparable damage.
Disassembly cleaning
Disassembly cleaning method should only be performed when the unit is considerable dirty and cannot be sufficiently
cleaned by air spraying alone.
Be sure to readjust the optical system after performing disassembly cleaning.
1. Remove the cabinet top and main units following to “Mechanical Disassembly”.
2. Remove the optical base top following to “Optical Unit Disassembly”. If the LCD panel needs cleaning, remove
the LCD panel unit following to “LCD panel replacement”.
3. Clean the optical parts with a soft cloth. Clean extremely dirty areas using a cloth moistened with alcohol.
Caution:
The surface of the optical components consists of multiple dielectric layers with varying degrees of refraction. Never
use organic solvents (thinner, etc.) or any kind of cleanser on these components.
Since the LCD panel is equipped with an electronic circuit, never use any liquids (water, etc.) to clean the unit. Use of
liquid may cause the unit to malfunction.
Unplug the AC power cord before cleaning.
Gently wipe the projection lens with a cleaning cloth that contains a small
amount of non-abrasive camera lens cleaner, or use a lens cleaning paper or
commercially available air blower to clean the lens.
Avoid using an excessive amount of cleaner. Abrasive cleaners, solvents, or
other harsh chemicals might scratch the surface of the lens.
After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized glass,
lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit.
Remove dust and other particles using air spray. If dirt cannot be removed by air spray, disassemble and clean the
optical unit.
