  Overview
Installing/replacing the remote control battery
1. Pull out the battery holder, as illustrated. Push and hold the 
locking arm whilst pulling out the battery holder.
2. Insert the new battery in the holder. Note the positive 
polarity should face outward.
3. Push the holder into the remote control.
•  Avoid leaving the remote control and battery in an excessive heat 
or humid environment like the kitchen, bathroom, sauna, 
sunroom or in a closed car.
•  Replace only with the same or equivalent type recommended by 
the battery manufacturer.
•  Dispose of the used batteries according to the manufacturers instructions and local environment 
regulations for your region.
•  Never throw the batteries into a fire. There may be danger of an explosion.
•  If the batteries are drained or if you will not be using the remote control for an extended period of time, 
remove the batteries to avoid damage to the remote control from possible battery leakage.
Remote control effective range
The remote control must be held at an angle within 30 degrees perpendicular to the projectors 
IR remote control sensor(s) to function correctly. The distance between the remote control and 
the sensor(s) should not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between the remote control and the IR sensor(s) on the 
projector.

  Installation
Obtaining a preferred projected image size
The projected image size is determined by the distance from the projector lens to the screen, the 
zoom setting, and the video format.
Projection dimensions
Use the illustration and the table below to help you determine the projection distance.
All measurements are approximate and may vary from the actual sizes. If you want a permanent 
installation of the projector, we recommend that you use the actual projector to physically test the 
projection size, distance, and the projectors optical characteristics prior to the installation. This helps you 
determine the exact mounting position which best suits your installation.

							14 Installation  
Shifting the projection lens vertically
The vertical lens shift control provides flexibility for installing your projector. It allows the projector 
to be positioned slightly above or below the top level of the projected images. 
The lens shift (offset) is expressed as a percentage of the projected image height. It is measured 
as an offset from the projected images vertical center. Use the lever to shift the projection lens 
upwards or downwards within the allowable range depending on your desired image position. 
To shift the lens:
1. Press down lightly on the lens adjustment panel cover switch (indicated by a dot) to click it 
open.
2. Lift the lens adjustment panel cover up.
3. Turn the lens shift ring to adjust the projected image position.
4. When done, press down and click close the lens adjustment panel cover.
•  When the screen position is fixed
•  When the projector position is fixed
•  Do not over-tighten the lever.
•  Lens shift adjustment does not result in a degraded picture quality. In the unlikely event that the image 
distortion is produced, see Adjusting the projected image for details.

							16 Operation  
Operation
Starting up the projector
1. Plug the power cable into the projector and a power outlet. 
Turn on the power outlet switch (where fitted). The POWER 
indicator light on the projector lights orange after power 
has been applied.
Please use the supplied power cable to avoid possible dangers such 
as electric shock and fire.
2. Press   to start the projector. The POWER indicator light 
flashes green and stays green when the projector is on. 
The fans start operating, and a start-up image displays on 
the screen while it warms up. The projector does not respond to further commands while it is 
warming up.
Shutting down the projector
1. Press  . The projector displays a shutdown confirmation message.
2. Press   a second time.
 The POWER indicator light flashes 
orange and the fans run for about two minutes to cool the 
lamp. The projector doesn’t respond to any commands 
during the cooling process. 
3. When the cooling process ends, the POWER indicator light 
will show a solid orange.
If the projector will not be used for an extended period, 
unplug the power cable from the power outlet.
Avoid turning on the projector immediately after turning it off as excessive heat may shorten lamp life. The 
actual lamp life may vary due to different environmental conditions and usage.

  Operation
Selecting an input source
The projector can be connected to multiple equipment at the same time. However, it only 
displays one full screen at a time. When starting up, the projector automatically searches for the 
available signals.
If you want the projector to always automatically search for the signals\
:
•  Go to the  SOURCE menu, and then enable  Quick Auto Search. (see Quick Auto Search 
on page 25 )
To select the video source:
1. Press  SOURCE to display the source selection bar. 
2. Press  / until your desired signal is selected and press  ENTER.
Once detected, the selected source information displays on the screen for seconds. If there 
are multiple pieces of equipment connected to the projector, repeat steps 1-2 to search for 
another signal.
Refer to Projector specifications  for the native display resolution of this projector. 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 dependin g upon the Aspect Ratio setting, which may cause 
some image distortion or loss of picture clarity. See  Aspect Ratio for details. 
						

							18 Operation  
Adjusting the projected image
Adjusting the projection angle 
The projector is equipped with 2 adjuster feet. These 
adjusters change the image height and projection angle. 
Screw the feet in or out as appropriate to aim and level the 
projection angle.
If the screen and the projector are not perpendicular to each 
other, the projected image becomes vertical trapezoidal. To 
correct this, see Auto-adjusting the image for details.
Auto-adjusting the image
In some cases, you may wish to optimize the picture 
quality of PC signal. To do this, press AUTO. 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 input source information will be displayed in the corner of the screen for 3 seconds.
This function is only available when PC signal is selected.
Fine-tuning the image size and clarity
To adjust the projected picture size, turn the zoom ring on the projector after opening the lens 
adjustment panel cover. 
To sharpen the picture, rotate the focus ring on the projector after opening the lens adjustment 
panel cover.
Do not look into the lens while the 
lamp is on. The strong light from 
the lamp may cause damage to 
your eyes.
Be careful when you press the 
quick-release button as it is close 
to the exhaust vent where hot air 
comes from.

  Operation
Correcting keystone
Keystoning refers to the situation where the projected image is noticeably wider at either the top 
or bottom. It occurs when the projector is not perpendicular to the screen.
