Maintenance
 
■ Lamp unit
The lamp unit is a consumable component. Check the usage duration in the\
 [PROJECTOR SETUP] menu  
[STATUS] (
 page 64) and perform regular replacement. 
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 (ET-LAD60A: 1 pc, ET-LAD60AW: 2 pcs).
Attention  
z
Do not replace the lamp unit when it is hot. (Wait at least one hour after use.)
The inside of the cover can become very hot, take care to  avoid burn injuries. 
 
■ Notes on the replacement of the lamp unit 
 
z
Since the luminous lamp is made of glass, it may burst if dropped or hit\
 with a hard object. 
Please handle with care. 
 
z
A Phillips screwdriver is necessary when replacing the lamp unit. 
 
z
When replacing the lamp unit, be sure to hold it by the handle. 
 
z
The lamp may burst. Replace the lamp unit carefully so that the broken p\
ieces of the lamp glass will not 
s

catter. When the projector is mounted on the ceiling, do not make the replacem\
ent directly under the lamp 
unit or put your face near it. 
 
z
The lamp contains mercury. When disposing of used lamps, ask your nearest ward office or dealer about 
proper disposal of the unit. 
Attention  
z
Use only specified lamp units. 
 
z
The part numbers of accessories and separately sold componen ts 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 2 000 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 kept. T
 he unit can damage the 
projector if it has not been replaced after 2 000 hours of usage. Thus, the lamp automatically turns off after 
approximately ten minutes. 
On screenLamp indicator
Over 1 800 hours The message is displayed for 30 seconds. 
Pressing any button on the control panel 
or remote control within 30 seconds will 
clear the message. 
Lights in red even during the standby 
mode. (only the corresponding lamp 
lights up)
Over 2 000 hours The message remains displayed until you 
press any button. 
Note  
z
2 000 hours of use is a rough guideline, but this is not a guarantee.

Attention  
z
When a command is transmitted after the lamp turned on, there may be a d\
elay in response or the command 
may not be executed. Try sending any command after 60 seconds. 
 
z
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 transm\
itting a command which does not 
ne ed a parameter,
  a colon (:) is not necessary. 
Note  
z
If a command cannot be executed, a  “
ER401 ”
 response is sent from the projector to the computer. 
 
z
If an invalid parameter is sent, a  “
ER402 ”
 response is sent from the projector to the computer. 
 
z
ID transmission in RS-232C supports ZZ (ALL) and the 01 to 64 and 0A to 0Z groups. 
 
z
If a command is sent with a specified ID, a response will be sent to  the computer only in the following cases. 
–

 It matches the projector ID
– ID setting is set to ALL and responding (ID ALL) is [ON]
– ID setting is set to Group and responding (ID Group) is [ON]
