CautionTurn off the power of both the projector and computer before connecting.
Connect the computer to the control terminal of the projector using an appropriate cable.
Refer to the instruction manual of each device before connecting.
(1)  Connect the projector and the mouse terminal of computer using an appropriate cable, while the
projector and the computer are turn off.
(2)  Turn the main power switch of the projector on and press the STANDBY/ON button. The indicator
will light. (The ON indicator will light up green.).
(3)  Press the INPUT of the projector or RGB button of the remote control transmitter and select the 
input connection.
(4)  Turn on the computer.
(5)  Start mouse emulation mode.
If can not start mouse emulation, reset the computer. (With soft reset or reset switch)
(6)  See on the page 9 about to operate the remote control transmitter.
Caution : Mouse cannot be operated while start up screen or menu screen is being displayed.
Caution·In some note computers which have internal pointing device, mouse emulation dont work
without setting the internal pointing device disabled. In this case, set the internal pointing
device disabled in BIOS setting. After setting in BIOS, operate (1) ~ (5) Please check its
hardware manuals to disable internal pointing device in BIOS setting.
·In some computers, mouse emulation dont work without the utility program. In this case,

The procedure of getting the Projector status
(1)Computer sends the command 20H+yyH to Projector.
(2)Projector reply the command 1xH+yyH+data bytes.
The procedure of setting the Projector status
(1)Computer sends the command 3xH+yyH+data bytes.
(2)Projector changes it’s status.
(3)Projector reply the command 1xH+yyH+data bytes which indicate status.
The procedure of default setting the Projector status
(1)Computer sends the command 40H+yyH
(2)Projector changes its status to default setting.
(3)Projector reply the command 1xH+yyH+data bytes which indicate default.
Connection to the control signal terminal (continued)
Caution
The example of command error
When projector cannot accept command from PC, error code 00H+yyH is sent back. 
(in a case when command code 2xH, 3xH or 4xH+yyH+data is sent from PC to projector)
The example of data error
When projector cannot accept command from PC, error code with data 00H+yyH+data is sent back as it
is. (in a case when command code 2xH, 3xH or 4xH+yyH+data is sent from PC to projector)
When data is longer than required data code length, projector ignores excess data code.
When data is shorter than required data code length, projector sends back error code shown above.
The example of framing error
Projector sends error code 70H+70H up to 10 times at intervals of 1 second until any answer is received. 
The interval of command bytes and data bytes
After command code 2xH, 3xH or 4xH is sent from PC, if command or data is not sent within 500ms,
projector sends back error command 70H+70H. If no answer is sent within 1 second from that time,
framing error is assumed.
Caution·The interval of command bytes and data bytes must be over 1mS and under 500mS.  If it is
under 1mS, it may be treat as framing error.
·After projector has sent back answer code, when next command is to be sent from PC, allow
for an interval of 40ms or more between answer code and other code. ·(3) data bytes is not always same as (1) data bytes. If projector cannot realize the status of (1)
data bytes, projector set the proper status and reply this new setting data bytes or projector
reply the error reply 0xH+yyH+data bytes same as (1).
·When only power control (POWER COMMAND) is performed, it takes about 2~140 seconds
between sending set code and receiving answering code.

Lamp
Light source lamp has a service life. 
The picture will become dark or color will be poor when the lamp is used\
 for a long time.
If usage of lamp is continued in such cases, it could cause a malfunctio\
n. Replace lamp with new one.
As reference for replacement time, indicator will operate or message wil\
l be displayed when the power is
turned on, as shown on page 30~31. In these cases the lamp should be rep\
laced. Consult your dealer.
1. How to replace lamp
Turn the main power switch off and disconnect the power 
plug from the power outlet.
1
Remove the lamp cover.
·If lamp is hot at this time, this could cause burn. Wait 
for minimum 45 minutes until lamp is cooled down.
· Loosen a screw and remove the cover.2
Loosen two screws and pull 
the handle to remove the
lamp.
· If the screws are not loosened completely, your fingers 
may be damaged.

(Option lamp : Lamp unit DT00236)
Caution ·For disposal of used lamp, treat according to the instruction of communi\
ty authorities.
· Since the lamp is made of glass, do not apply shock to it and do not scr\
atch it. 
· Also, do not use old lamp.  This could also cause 
explosion of the lamp.
· If it is probable that the lamp has exploded
(explosive sound is heard), disconnect the power
plug from the power outlet and ask your dealer to
replace lamp.  The lamp is covered by front glass
and air-tight structure, but, in rare cases, the
reflector and the inside of the projector may be damaged by scattered br\
oken pieces of glass,
and broken pieces could cause injury when being handled
.
·Do not insert your hand into the box after the lamp is removed. 
(There are optical parts inside. If touched by hand, it may result in c\
olor unevenness, etc.)
Caution Also LAMP indicator will light when the lamp becomes too hot. Turn off t\
he power and let the 
projector cool for 45 minutes. Turn on. If LAMP indicator still lights u\
p red, contact your
dealer.
