Connecting with your devices (continued)
(continued on next page)
• 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  (
40). 
-   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.

Connecting with your devices (continued)
Setting up
•  If you insert a USB storage device, such as a USB memory, into the USB TYPE 
A port and select the port as the input source, you can view images stored in the 
device (
77).
•    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.  (
46)  
    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. (
20)   
    Even when the sound of projector is set to mute mode by the AUDIO SOURCE 
function (
45), 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. (
20)
• If a loud feedback noise is produced from the speaker, move the 
microphone away from the speaker. 
•  This projector doesn't support plug-in power for the microphone.

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.
Installing the batteries
Please insert the batteries into the remote control before using it. If the remote control 
starts to malfunction, try to replace the batteries. If you will not use the remote control for 
long period, remove the batteries from the remote control and store them in a safe place.
1.Holding the hook part of the battery 
cover, remove it.
2.Align and insert the two AA batteries 
(HITACHI MAXELL, Part No.LR6 or R6P) 
according to their plus and minus terminals 
as indicated in the remote control.
3.Replace the battery cover in the direction of the arrow and snap it back into place.
►Always handle the batteries with care and use them only as 
directed. Improper use may result in battery explosion, cracking or leakage, 
which could result in fire, injury and/or pollution of the surrounding environment.
• Be sure to use only the batteries specified. Do not use batteries of dif ferent 
types at the same time. Do not mix a new battery with used one. 
• 
Make sure the plus and minus terminals are correctly aligned when loading a battery.
• Keep a battery away from children and pets.
• Do not recharge, short circuit, solder or disassemble a battery .
• 
Do not place a battery in a fire or water. Keep batteries in a dark, cool and dry place.
• If you observe battery leakage, wipe out the leakage and then replace a battery. 
If the leakage adheres to your body or clothes, rinse well with water immediately .
• Obey the local laws on disposing the battery. WARNING
• 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.
