Chapter 2 Getting Started — Setting up
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.

Connections
Before connecting to the projector
r
f Before connecting, carefully read the operating instructions for the external device to be connected.
r
f Turn off the power of all devices before connecting cables.
r
f 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.
r
f Video 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.
r
f The projector accepts video signals, S video signals, analog RGB signals (synchronous signals are 
TTL level), and digital signals.
r
f Some computer models are not compatible with the projector.
r
f Use a cable compensator when you connect devices to the projector using long cables. Otherwise the image may not display properly
.
r
f Refer to “List of compatible signals” (
x page 123) for the types of video signals that can be used with the projector
.

and the image will soon be projected on the screen.
Note
r
f 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 off and the projection starts. Refer to “Managing the indicated problems” (
x page 108) for the indicator status.
r
f If 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)
