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 range
Front adjustable f\meet: 12 mm \f15/32\b)
Rear adjustable fe\met: 12 mm \f15/32\b)
Attention
 zHot air is expelled from the air exhaust port. Do not touch the air exhaust port directly when adjusting the 
adjustable feet. (

tore the removed lens fixing screw in a safe place.
Move the lens to the home position before replacing or removing the lens. ( page 53)
Attention
 z Replace the projection lens after turning of

f the power of the projector.
 z Do not touch the lens signal receiver

. Dust or dirt may cause defective contact.
 z Do not touch the lens surface with your bare hands.
 zBefore attaching the projection lens, remove the lens cover attached to the projection lens.   
						

							Connecting
44 - ENGLISH
Getting Started
Before connecting
 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 (including 

Y/C 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 167) for the types of video signals that can be used with the 
projector
