Playing sound through the projector
You can make use of the projector (mixed mono) speaker in your presentations, and also 
connect separate amplified speakers to the AUDIO OUT socket of the projector.
If you have a separate sound system, you will most likely want to connect the audio output 
of your Video source device to that sound system, instead of to the mono audio projector.
You can also use a microphone to output the sound through the projector speaker.
Once connected, the audio can be controlled by the projector On-Screen Display (OSD) 
menus. See Audio Settings on page 61 for details.
The table below describes the connection methods for different devices, and where the 
sound is from.
About the microphone input
•  If you wish to use a microphone, connect a 3.5 mini jack cable microphone to the 
projector.
•  You can use a wireless microphone as long as a wireless module is attached to the 
projector’s microphone input jack and it works well with the associated devices. To 
ensure a quality use of the wireless microphone, it is recommended that your 
microphone conforms to the specifications listed in the table below. 
•  There are two ways to adjust microphone volumes.
• Directly set microphone volume levels in the SYSTEM SETUP: Advanced > 
Audio Settings > Microphone Volume menu or press MIC/VOL keys (+/-) on 
the remote control.
• Set projector volume levels in the SYSTEM SETUP: Advanced > Audio Settings 
> Volume menu, or press VOLUME+/VOLUME- on the remote control. (The 
projector volume setting will affect the microphone volume.)
•  To make the microphone input available when the projector is in standby mode, turn on 
the SYSTEM SETUP: Advanced > Standby Settings > Microphone menu.
•  If the microphone is not working, check the volume setting and cable connection.

							Connection 22•  You might get feedback noise from the microphone when you are too close to the 
speaker of the projector. Move the microphone away from the speaker of the projector. 
The greater volume you require, the greater distance you need to be away from the 
speaker to prevent the noise.

Operation
Starting up the projector
1. Plug the power cord into the projector and into a 
power outlet. Turn on the power outlet switch 
(where fitted). Check that the POWER indicator 
light on the projector lights orange after power has 
been applied.
Please use the original accessories (e.g. power cord) only 
with the device to avoid possible dangers such as electric 
shock and fire.
2. Press  POWER on the projector or   ON on the remote control to start the 
projector. As soon as the lamp lights up, a Power On Tone will be heard. The 
POWER indicator light flashes green and stays green when the projector is on.
The start up procedure takes about 30 seconds. In the later stage of start up, a startup 
logo is projected.
(If necessary) Rotate the focus ring to adjust the image clearness.
To turn off the ring tone, see Turning off the Power On/Off Ring Tone on page 39 for 
details.
If the projector is still hot from previous activity, it will run the cooling fan for approximately 90 
seconds before energizing the lamp.
3. If the projector is activated for the first time, 
select your OSD language following the on-
screen instructions.
4. If you are prompted for a password, press the 
arrow keys to enter a six-digit password. See 
Utilizing the password function on page 27 for 
details.
5. Switch all of the connected equipment on.
6. The projector will start to search for input 
signals. The current input signal being scanned 
displays in the upper left corner of the screen. If 
the projector doesnt detect a valid signal, the message “No Signal” will continue 
displaying until an input signal is found.
Yo u  c a n  a l s o  p r e s s  SOURCE on the projector or remote control to select your desired 
input signal. See Switching input signal on page 30 for details.
If the frequency/resolution of the input signal exceeds the projectors operating range, you will 
see the message “Out of Range” displayed on a blank screen. Please change to an input 
signal which is compatible with the projectors resolution or set the input signal to a lower 
setting. See Timing chart on page 74 for details. 
						

							Operation 24
Adjusting the projected image
Adjusting the projection angle
The projector is equipped with 1 quick-release adjuster foot and 2 rear adjuster feet. These 
adjusters change the image height and projection angle. To adjust the projector:
1. Press the quick-release button and lift the 
front of the projector. Once the image is 
positioned where you want it, release the 
quick-release button to lock the foot in 
position.
2. Screw the rear adjuster feet to fine-tune the 
horizontal angle.
To retract the foot, hold up the projector while 
pressing the quick-release button, then slowly 
lower the projector. Screw the rear adjuster feet 
in a reverse direction.
If the projector is not placed on a flat surface or 
the screen and the projector are not 
perpendicular to each other, the projected image 
becomes trapezoidal. To correct this situation, 
see Correcting keystone on page 25 for details.
Auto-adjusting the image
In some cases, you may need to optimize the picture quality. To do this, press AUTO on the 
projector or remote control. Within 3 seconds, the built-in Intelligent Auto Adjustment 
function will re-adjust the values of Frequency and Clock to provide the best picture quality. 
The current source information will be displayed in the corner of the screen for 3 seconds.
•  The screen will be blank while AUTO is functioning.
•  This function is only available when PC signal (analog RGB) is selected.

							Operation 30
Switching input signal
The projector can be connected to multiple devices at the same time. However, it can only 
display one full screen at a time. When starting up, the projector automatically searches for 
the available signals.
Be sure the Quick Auto Search function in the SOURCE menu is On if you want the 
projector to automatically search for the signals.
To select the source:
•  Using the remote control or projector
Press one of the Source buttons on the remote control, 
or press SOURCE on the projector repeatedly until 
your desired signal is selected.
•  Using the OSD menu
1. Press SOURCE on the projector or remote 
control. A source selection bar is displayed. 
2. Press / until your desired signal is selected 
and press MODE/ENTER.
Once detected, the selected source information 
will be displayed at the corner of the screen for 
seconds. If there is multiple equipment connected 
to the projector, repeat steps 1-2 to search for 
another signal.
•  The brightness level of the projected image will 
change accordingly when you switch between 
different input signals. Data (graphic) PC 
presentations using mostly static images are 
generally brighter than Video using mostly moving 
images (movies).
•  The native display resolution of this projector is in a 4:3 aspect ratio. For best display 
picture results, you should select and use an input signal which outputs at this resolution. 
Any other resolutions will be scaled by the projector depending upon the “aspect ratio” 
setting, which may cause some image distortion or loss of picture clarity. See Selecting 
the aspect ratio on page 31 for details.
•  Firewall in the PC must be switched off to allow Q Presenter and USB Display to work.
Changing Color Space (MX762 ST only)
