Adjusting the projector's elevator
When the place to put the projector is slightly uneven to the left or right, use the 
elevator feet to place the projector horizontally.
Using the feet can also tilt the projector in order to project at 
a suitable angle to the screen, elevating the front side of the 
projector within 8 degrees.
This projector has 2 elevator feet and 2 elevator knobs. An elevator foot is 
adjustable while pulling up the elevator knob on the same side as it.
1.Holding the projector, pull the elevator knobs up to loose the elevator feet.
2.Position the front side of the projector to the desired height.
3.Release the elevator knobs in order to lock the elevator feet.
4. After making sure that the elevator feet are locked, put the projector gently.
5. If necessary, the elevator feet can be manually twisted to make more precise 
adjustments. Hold the projector when twisting the feet.
►Do not handle the elevator knobs without holding the projector, 
since the projector may drop down.
►Do not tilt the projector other than elevating its front within 8 degrees using 
the adjuster feet. A tilt of the projector exceeding the restriction could cause 
malfunction or shortening the lifetime of consumables, or the projector itself.CAUTION

Setting up
Connecting your devices (continued)
• Be sure to read the manuals for devices before connecting them to the projector, 
and make sure that all the devices are suitable to be connected with this product. Before 
connecting to a PC, check the signal level, the signal timing, and the resolution.
-  Be sure to consult to the administrator of the network. Do not connect LAN port to any 
network that might have the excessive voltage.
- Some signal may need an adapter to input this projector.
-  Some PCs have multiple screen display modes that may include some signals which 
are not supported by this projector.
-  
Although the projector can display signals with resolution up to UXGA (1600X1200), the signal will be 
converted to the projector’s panel resolution before being displayed. The best display performance 
will be achieved if the resolutions of the input signal and the projector panel are identical.
• While connecting, make sure that the shape of the cable's connector fits the port to 
connect with. And be sure to tighten the screws on connectors with screws.
• When connecting a laptop PC to the projector, be sure to activate the PC’s external 
RGB output. (Set the laptop PC to CRT display or to simultaneous LCD and CRT 
display.) For details on how this is done, please refer to the instruction manual of the 
corresponding laptop PC.
• When the picture resolution is changed on a computer depending on an input, 
automatic adjustment function may take some time and may not be completed. In this 
case, you may not be able to see a check box to select “Yes/No” for the new resolution 
on Windows. Then the resolution will go back to the original. It might be recommended 
to use other CRT or LCD monitors to change the resolution.
• In some cases, this projector may not display a proper picture or display any picture on 
screen. For example, automatic adjustment may not function correctly with some input 
signals. An input signal of composite sync or sync on G may confuse this projector, so 
the projector may not display a proper picture.
• 
The HDMI port of this model is compatible with HDCP (High-bandwidth Digital Content Protection) 
and therefore capable of displaying a video signal from HDCP compatible DVD players or the like.
NOTE

About the remote control signal
The remote control works with the projector’s remote sensors. This projector has 
three remote sensors on the front, on the top, and on the back.
The sensors can be respectively turned active or inactive using the “REMOTE 
RECEIV.” in the SERVICE item of OPTION menu (
46). Each sensor senses the 
signal within the following range when the sensor is active.
The front and top sensors:
60 degrees (30 degrees to the left and right of the 
sensor) within 3 meters about.
The back sensor:
40 degrees (20 degrees to the left and right of the 
sensor) within 3 meters about.
• The remote control signal reflected in 
the screen or the like may be available. If it is 
difficult to send the signal to the sensor directly, 
attempt to make the signal reflect.
• The remote control uses infrared light to send 
signals to the projector (Class 1 LED), so be 
sure to use the remote control in an area free 
from obstacles that could block the remote 
control’s signal to the projector.
• The remote control may not work correctly if 
strong light (such as direct sun light) or light 
from an extremely close range (such as from 
an inverter fluorescent lamp) shines on the 
remote sensor of the projector. Adjust the 
position of projector avoiding those lights. NOTE
Changing the frequency of  remote control signal
The accessory remote control has the choice of 
the mode 1 or the mode 2, in the frequency of 
its signal. If the remote control does not function 
properly, attempt to change the signal frequency.
Please remember that the “REMOTE FREQ.” in 
SERVICE item of OPTION menu (
46) of the 
projector to be controlled should be set to the 
same mode as the remote control.
To set the mode of the remote control, slide the 
knob of the frequency switch inside the battery 
cover into the position indicated by the mode 
number to choose.
