Installation
Connecting the AC Power Cord
This projector uses nominal input voltages of 100–240 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 center.
Connect the projector with all peripheral equipment before 
turning it on.
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.
Connect the AC power cord 
(supplied) to the projector.
  CAUTION
The AC outlet must be near this equipment and must be 
easily accessible.

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 61-62 for 
locking operation of the projector with your PIN code.
Enter a 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 OK 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 as a 
reminder.
After the OK icon disappears, 
you can operate the projector.

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.
Turning Off the Projector
Press the POWER button on the remote controller or 
on the top control, and Power off? appears on the 
screen.
Press the POWER 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  63.) 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 Direct power on function is set to On, the 
projector will be turned on automatically by connecting 
the AC power cord to an AC outlet.  (p. 59)
 • 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 66.
 • While the POWER indicator is blinking, the lamp is 
being cooled down and the projector can not 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. 
 • To protect the component parts inside the projector, the 
fans normally start running again in approximately 40 
seconds after turning off the projector. This is NORMAL 
operation and not a malfunction.
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.
Basic Operation
You can disconnect the power cord from the 
wall outlet or turn off the breaker even during 
projection without pressing the POWER button.
Note:
•   When using the Direct Power Off function, 
you can not restart the projector immediately 
after the power is disconnected. If the external 
power supply is suddenly cut off, the fans 
stop immediately. The lamp remains high 
temperature and needs to be cooled.
