2) Dry the air filter unit.
r
f Let the unit naturally dry off in a well-ventilated place where 
there is little dust and the unit is protected from direct sunlight.
r
f Do not dry using drying devices such as dryers.
r
f When the air filter unit is dry, proceed to the procedure 
described in “Attaching the air filter unit” (
x page 111).
Attaching the air filter unit
1) Attach the air filter unit to the projector.
r
f The top and bottom of the air filter unit are different.
(Make sure of the direction of the arrow (
L).)
r
f Attach in reverse order of Step 
2) in “Pulling out the air filter 
unit” ( x page 110).
2) Attach the air filter cover to the projector and 
use a Phillips screwdriver to tighten the air 
filter cover screw.
r
f Attach in reverse order of Step 
1) in “Pulling out the air filter 
unit” ( x page 110).
Attention
r
f After washing the air filter unit, dry it thoroughly before attaching it back to the projector
. Attaching a wet unit will cause an electric shock or 
malfunction.
r
f Do not disassemble the air filter unit.
Note
r
f Make sure that the air filter unit is properly attached before using the projector
. If not properly attached, the projector will suck in dirt and 
dust which causes malfunction and the power to switch off 10 minutes later. (The time remaining until the power switches off is displayed in 
1-minute increments.)
r
f Replace the air filter unit with a replacement filter unit (ET-EMF300) if it is damaged or if the dirt does not come off even after washing.
r
f Air filter replacement is recommended after cleaning the unit two times.
r
f The dust-proof properties may be reduced after each cleaning.
Replacing the unit
Air filter unit
If dirt does not come off even if the unit is maintained, it is time for the unit to be replaced.
The replacement filter unit (Model No.: ET-EMF300) is an optional accessory. To purchase the product, consult your dealer.
Replacing the air filter unit
Attention
r
f Make sure to turn off the power before replacing the air filter unit.
r
f When replacing the unit, make sure that the projector is stable. Perform the replacement in a safe place where the projector will not be 
damaged even if you drop the air filter unit.
1) Pull out the air filter unit.
r
f Refer to “Pulling out the air filter unit” (
x page 110).
2) Attach the replacement filter unit optional 
accessory (Model No.: ET-EMF300) to the 
projector body.
r
f The top and bottom of the air filter unit are different. (Make sure 
of the direction of the arrow (
L).)
r
f Refer to “Attaching the air filter unit” (
x page 111).
Attention
r
f When switching on the projector, make sure that the air filter unit is installed. If not properly attached, the projector will suck in dirt and dust 
which causes malfunction and the power to switch off 10 minutes later. (The time remaining until the power switches off is displayed in 
1-minute increments.)

Chapter 5 Maintenance — Maintenance/replacement
Note
r
f The replacement cycle of the air filter unit varies greatly depending on the usage environment.
Lamp unit
The lamp unit is a consumable component. Check the lamp usage time in [PROJECT
OR SETUP]
 [STATUS] (
x page 79) in the menu and 
change the lamp periodically.
It is recommended that you request a qualified technician to replace the lamp unit. Consult your dealer .
Consult your dealer to purchase a replacement lamp unit (Model No.: ET -LAD60A (1 bulb), ET-LAD60AW (2 bulbs)).
Warning
r
f Replace the lamp unit after the lamp has cooled (after waiting at least\
 one hour).
The high internal temperature of the cover will cause burns.
Notes on the replacement of the lamp unit
r
f Since the luminous lamp is made of glass, it may burst if dropped or hit with a hard object.
Please handle with care.
r
f A Phillips screwdriver is necessary when replacing the lamp unit.
r
f Make sure you hold the lamp unit by its handles during replacement.
r
f The lamp may burst. Replace the lamp unit carefully so that the broken pieces of the lamp glass will not scatter
. If the projector is mounted 
to the ceiling, do not make the replacement directly beneath the lamp un\
it or put your face near it.
r
f The lamp contains mercury. When disposing of used lamp units, contact your local authorities or d\
ealer for correct methods of disposal.
Attention
r
f Use only specified lamp units.
Note
r
f The model numbers of accessories and optional components are subject to change without notice.
When to replace the lamp unit
The lamp unit is a consumable component. Since its brightness gradually \
decreases over time, it is necessary to replace it regularly
. The 
estimated duration before replacement is 2 500 hours. However, this may be shortened depending on individual lamp characteristics, usage 
conditions, and the installation environment. Therefore, it is strongly recommended that a replacement lamp unit be prepared. If the lamp is not 
replaced after 2 500 hours of use, a malfunction will occur and the projector will automatically switch of f after approximately ten minutes.

Replacing the lamp unit
Attention
r
f When the projector is mounted on the ceiling, do not perform tasks while your face is near the lamp unit.
r
f Make sure to attach the lamp unit and lamp unit cover properly.
r
f If the lamp unit is not installed properly, remove it and then attach it again. Pushing it in forcibly may break the connector.

Attention
r
f If a command is transmitted after the lamp starts illuminating, there may be a delay in response or the command may not be executed. 
Try 
sending or receiving any command after 60 seconds.
r
f When transmitting multiple commands, be sure to wait until 0.5 seconds has elapsed after receiving the response from the projector before 
sending the next command. When transmitting a command which does not need a parameter
, a colon (:) is not necessary.
Note
r
f If a command cannot be executed, an “ER401” response is sent from the projector to the computer
.
r
f If an invalid parameter is sent, an “ER402” response is sent from the projector to the computer
.
r
f ID transmission in RS-232C supports ZZ (ALL) and 01 to 64, as well as 0A
 to 0Z groups.
r
f If a command is sent with a specified ID, a response will be sent to the computer only in the following cases.
r
g It matches the projector ID
r
g ID setting is set to ALL and [RESPONSE(ID ALL)] is [ON]
r
g ID setting is set to GROUP and [RESPONSE(ID GROUP)] is [ON]
r
f STX and ETX are character codes. STX shown in hexadecimal is 02, and ETX shown in hexadecimal is 03.
When multiple projectors are controlled
When multiple projectors are all controlled
When controlling multiple projectors together via RS-232C, perform the following settings.
1) Set a different ID for each projector.
2) Set [RESPONSE(ID ALL)] to [ON] in only one 
projector.
3) Set [RESPONSE(ID ALL)] to [OFF] for all other 
projectors set in Step 2).
When multiple projectors are all controlled by group unit
When controlling multiple projectors by group unit via RS-232C, perform the following settings.
1) Set a different ID for each projector.
2) Set [RESPONSE(ID GROUP)] to [ON] in only 
one projector.
3) Set [RESPONSE(ID GROUP)] to [OFF] for all 
other projectors set in Step 2).
Note
r
f There will be no response if 2 or more projectors have [RESPONSE(ID 
ALL)] set to [ON].
r
f There will be no response if 2 or more projectors of the same group have [RESPONSE(ID GROUP)] set to [ON].
r
f When setting multiple groups, set [RESPONSE(ID ALL)] to [ON] in only one projector in each group.
