Remote control
The  2  different  remote  control  codes  (Code  1–Code  2)  are 
assigned to this projector. Switching the remote
control  codes  prevents  interference  from  other  remote 
controls when several projectors or video equipment
next  to  each  other  are  operated  at  the  same  time.  Change 
the remote control code for the projector first before
changing  that  for  the  remote  control.  See  "Remote  control" 
in the Setting Menu on page 53.
Press and hold the MENU and IMAGE buttons for more
than five seconds to switch between the Code 1 and Code
. The initial code is set to Code 1.

Installation
This  projector  uses  nominal  input  voltages  of  100-120  V  or 
200–240  V AC  and  it  automatically  selects  the  correct  input 
voltage.  It  is  designed  to  work  with  single-phase  power 
systems  having  a  grounded  neutral  conductor.  To  reduce 
the risk of electrical shock, do not plug into any other type of 
power system.
If  you  are  not  sure  of  the  type  of  power  being  supplied, 
consult your authorized dealer or service station.
Connect  the  projector  with  all  peripheral  equipment  before 
turning the projector on. (See pages 14-16 for connection)
Note:
     Unplug the AC power cord when the projector is not 
     in use.  When this projector is connected to an outlet
     with the AC power cord, it is in Stand-by mode and
     consumes a little electric power.

what is PIN code?
PIN (Personal Identification Number) code is a security 
code that allows the person who knows it to operate the 
projector. Setting a PIN code prevents unauthorized use of 
the projector.
A PIN code consists of a four-digit number. Refer to the PIN 
code lock function in the Setting Menu on pages 54-55 for 
locking operation of the projector with your PIN code.
Use the Point ▲▼ buttons to enter a number. Press the 
Point ► button to fix the number and move the red frame 
pointer to the next box. The number changes to “”. If you 
fixed an incorrect number, use the Point ◄ button to move 
the pointer to the number you want to correct, and then 
enter the correct number.
Repeat this step to complete entering a four-digit number.
After entering the four-digit number, move the pointer to Set. 
Press the SELECT button so that you can start to operate 
the projector.
If you entered an incorrect PIN code, PIN code and the 
number () will turn red for a moment. Enter the 
correct PIN code all over again.
CAUTION ON HANDLING PIN CODE
If you forget your PIN code, the projector can no 
longer be started. Take a special care in setting 
a new PIN code; write down the number in a 
column on page 80 of this manual and keep it 
on hand. Should the PIN code be missing or 
forgotten, consult your dealer or service center.
After the OK icon disappears, 
you can operate the projector.  
PIN Code Input Dialog Box
Note:
 • If the PIN code number is not entered within three 
minutes after the PIN code dialog box appeared, the 
projector will be turned off automatically.
 • The “1234” is set as the initial PIN code at the factory.

TO MAINTAIN THE LIFE OF THE LAMP, ONCE 
YOU TURN THE PROJECTOR ON, WAIT AT 
LEAST FIVE MINUTES BEFORE TURNING IT 
OFF.
Power off? disappears after 4 seconds.
Press  the  ON/STAND-BY  button  on  the  top  control  or 
on the remote control, and Power off? appears on the 
screen.
Press  the  ON/STAND-BY  button  again  to  turn  off  the 
projector. The POWER indicator starts to blink red, and 
the cooling fans keep running. (You can select the level 
of  fans’  quietness  and  speed.  See  “Fan”  on  page  56.) 
At this time, you can unplug the AC power cord even if 
the fans are still running.

3When  the  projector  has  cooled  down  enough,  the 
POWER  indicator  stops  blinking  and  you  can  turn  on 
the projector. 
Note:
 • When the On start function is set to On, the projector will 
be  turned  on  automatically  by  connecting  the AC  power 
cord to an AC outlet (p.51).
 • The running speed of cooling fans is changed according 
to the temperature inside the projector.
 • Do not put the projector in a case before the projector is 
cooled enough.
 • If the WARNING TEMP. indicator blinks or lights red, see 
“WARNING TEMP. indicator” on page 59.
 • While the POWER indicator is blinking, the lamp is being 
cooled down and the projector cannot be turned on. Wait 
until  the  POWER  indicator  stops  blinking  to  turn  on  the 
projector again.
  •  The  fan  rotation  will  terminate  directly  if  the  AC  power 
cord  is  unplugged  immediately  after  the  projector  is 
turned off.
  • The  projector  can  be  turned  on  after  the  POWER 
indicator  turns  red.  The  waiting  time  to  restart  will  be 
shortened when the normal power-off processing for fan 
    cooling  is  completed,  compared  with  the  time  the  AC 
power  cord  is  immediately  unplugged  after  the  power-
off. 
Basic Operation
DO NOT OPERATE THE PROJECTOR 
CONTINUOUSLY WITHOUT REST. 
CONTINUOUS USE MAY RESULT IN 
SHORTENING THE LAMP LIFE. TURN OFF THE 
PROJECTOR AND LET STAND FOR ABOUT AN 
HOUR IN EVERY 24 HOURS.
