Connecting with your devices (continued)
• Before connecting the projector to a computer, consult the computer’s 
manual and check the compatibility of the signal level, the synchronization 
methods and the display resolution output to the projector. 
-  Some signal may need an adapter to input this projector.
-  Some computers 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.
• If you connect this projector and a notebook computer, you need output the 
display to an external monitor, or output simultaneously to the internal display 
and an external monitor. Consult the computer's manual for the setting.
• Depending on the input signal, the automatic adjustment function of this 
projector may take some time and not function correctly. 
-  Note that a composite sync signal or sync-on-green signal may confuse the  automatic adjustment function of this projector (
28). 
-  If the automatic adjustment function does not work correctly, you may not see  the dialog to set the display resolution. In such a case, use an external display 
device. You may be able to see the dialog and set an appropriate display 
resolution.

Speakers          (with an amplifi er)Mic
• If a loud feedback noise is produced from the speaker, move the 
microphone away from the speaker.  NOTE
• You can connect a dynamic microphone to the  MIC port with a 3.5 mm mini-plug. 
In that case, the built-in speaker outputs the sound from the microphone, even 
while the sound from the projector is output. You can input line level signal to 
the MIC port from equipment such as wireless microphone. Select HIGH in the 
MIC LEVEL item of the AUDIO menu when you input line level audio signal to 
the MIC port. In the normal mode, the volume of the microphone can be adjusted 
separately from the volume of the projector using the menu (
49). In the standby 
mode, the volume of the microphone is adjustable with the VOLUME +/- buttons 
on the remote control, in synchronization with the volume of the projector (
23).
Even when the sound of projector is set to mute mode by the AUDIO SOURCE 
function (
49), the volume of the microphone is adjustable.
In both modes (standby or normal), the  MUTE button on the remote control 
works on the sounds of the microphone and the projector (
23).

About the remote control signal
The remote control works with the projector’s remote 
sensor. This projector has a remote sensor on the front.
The sensor senses the signal within the following range 
when the sensor is active:60 degrees (30 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
