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  55-56  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	CODEIf you forget your PIN code, the projector can no longer  be  started.  Take  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 top control or on the remote controller, 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 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 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.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 indicator blinks or lights red, see “WARNING indicator” on page 60. • 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.  •  For assisting the cooling fans’ operation, the projector is equipped with a large capacitor. While the projector is operating, the capacitor charges electricity. When disconnecting the AC plug from AC outlet, cooling fans start to run 1 minute until the capacitor is discharged.   • 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. 
DO	NOT	OPERATE	THE	PROjECTOR	CONTINUOUSLY 	WITHOUT	REST.	CONTINUOUS	USE	MAY 	RESULT	IN	SHORTENING	THE	LAMP 	LIFE.	TURN	OFF	THE	PROjECTOR	AND	LET	IT	STAND	FOR	ABOUT	 AN	HOUR	IN	EVERY 	24	HOURS.
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.
You can disconnect the power cord from the wall outlet or turn off the breaker even during projection without pressing the POWER button.
