Getting Started
Adjusting adjustable feet
Install the projector on a flat surface so that the front of the projector is parallel to the screen surface and the 
projection screen is rectangular.
If the screen is tilted downward, the projection screen can be adjusted to be rectangular by adjusting the 
adjustable feet. The adjustable feet can also be used to adjust the projector to be level when it is tilted in a 
horizontal direction.
Extend the adjustable feet by rotating in the direction shown in the figure and retract by rotating in the opposite 
direction.
Adjustable amount
Front adjustable f\meet: 30 mm \f1-3/1\b)
Attention
 zHot air is expelled from the air exhaust port when the lamp is on. Do not touch the air exhaust port directly 
when adjusting the adjustable feet.(

Getting Started
Before connecting to the projector
 zBefore connecting, carefully read the operating instructions for the external device to be connected.
 zT

urn off the power of all devices before connecting cables.
 z Acquire 

any connection cable necessary to connect the external device to the system that is either not supplied 
with the device or not available as an option.
 z V

ideo signals containing too much jitter may cause the images on the screen to randomly wobble or wafture. In 
this case, a time base corrector (TBC) must be connected.
 z The projector accepts video signals, S video signals, analog RGB signals (synchronous signals are 
TTL

 level), 
and digital signals.
 z Some computer models are not compatible with the projector

.
 zUse a cable compensator when you connect devices to the projector using long cables. Otherwise the image 
may not display properly

.
 zRefer to “List of compatible signals” ( page 120) for the types of video signals that can be used with the 
projector

projected on the screen.
Note
 z If the projector is switched on at about 0°C (32°F), 
a warm-up period of approximately five minutes 
may be necessary until a projection is displayed.
The temperature indicator  is lit during the 
warm-up period. When the warm-up is completed, 
the temperature indicator  turns of

f and the 
projection starts. Refer to “Managing the indicated 
problems” (
 page 104) for the indicator status.
 z I

f the operating environment temperature is low and 
warm-up takes more than 5 minutes, the projector 
will judge that a problem has occurred and the 
power will automatically be set to stand-by. If this 
happens, increase the operating environment 
temperature to 0°C (32°F) or higher, turn off the 
main power, and then turn on the power again.
 z If [PROJECT

OR SETUP] → [STANDBY MODE] 
(
 page 70) is set to [ECO] on the menu, there 
may be a 10 second display lag when the power 
is turned on compared to when the setting is 
[NORMAL].
 z If the  switch was turned  
during projection the last time that the direct power 
of

f function was used, and the 
switch is turned  while the main power plug 
connected to the outlet, the power indicator will light in green and the image will 
soon be projected on the screen.
Making adjustments and

Basic Operation
Switching off the projector
1) Press the power standby  button.
▶zThe [POWER OFF(ST ANDBY)] screen is 
displayed.
2) Use  ◀▶ to select [OK], and press the 
 button.
(Or press the power standby <

▶z Projection of the image will stop, and the power 
indicator  on the 
projector lights in orange.
(The fan keeps running.)
3) Wait until the power indicator  of the projector 
lights in red (and the fan stops) for 
approximately 170 seconds.
4)
 
Press the  side of the  switch to turn off the power

.
Note
▶zDo not turn on the power and project images 
immediately after turning the projector off.
T

urning on the power while the lamp is still hot may 
shorten the lamp life.
 z The lamp indicators will not light even if the power 
is switched on for about 75 seconds after the 
projector is switched of

f and the luminous lamp 
cooling has started. The indicators may not light 
when the power is switched on even after this time. 
In such a case, turn the power on again after the 
power indicator  lights in 
red.
▶z The projector consumes power even when the 
power standby <
> button is pressed and the 
power is switched off if the projector’s main 
power is on.
(when [STANDBY MODE] is set to [NORMAL])
When [STANDBY MODE] (
 page 70) is set to 
[ECO] on the menu, the power consumption during 
standby can be conserved.
Direct power off function
Even if the  switch is  during 
projection or immediately after the luminous lamp is 
turned off, the electricity stored in the room will drive 
the fan and cool the luminous lamp. When mounting 
on the ceiling or other environment where the 
projector  switch cannot easily be 
turned , the power can be shut down directly 
from the power breaker. This method is safe in the 
event of a blackout or if the power cord is removed 
directly after the projector is switched off.
Note
 z If the power was shut down directly from the power 
circuit breaker during projection the last time that 
the projector was used, the power indicator  will light in green a while after 
the power circuit breaker is turned on and then 
transition to image projection.
 z It may take more time than normal to project the 
next time that the power is turned on after direct 
power of

f is used to cool.
 zWhen packing for shipment or storage, ensure that 
the fan is stopped.
