Putting batteries 
WARNING  ►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 different types 
at the same time. Do not use 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 allow a battery in a fire or water. Keep batteries in a dark, cool and dry place. 
• Do not give the battery a physical impact. 
• If you observe a leakage of a battery, wipe out the flower and then replace a battery. 
If the flower adheres your body or clothes, rinse well with water immediately. 
• Obey the local laws on disposing a battery. 
To use the remote control, please load the batteries. Whenever the remote control 
starts to malfunction, replace the batteries. If you won’t use the remote control for 
an extended period, remove the batteries from the remote control and store them in 
a safe place. 
1. Remove the battery cover.   
Slide back and remove the battery cover in the direction of the arrow. 
 
2. Take old batteries out and/or put new batteries in. 
When putting in batteries, align and insert the two AA batteries according to 
their plus and minus terminals as indicated in the remote control. 
 
3. Close the battery cover. 
Replace the battery cover in the direction of the arrow and snap it back into 
place.

Using the remote control 
CAUTION  ►Be careful in handling the remote control. Incorrect handling 
could cause damage or malfunction. 
• Do not drop or otherwise expose the remote control to physical impact. 
• Do not get the remote control wet or place it on wet objects.   
• Remove the batteries from the remote control and store them in a safe place if 
you won’t be using the remote control for an extended period.   
• Replace the batteries whenever the remote control starts to malfunction.   
• When strong lights such as direct sunlight or light from an extremely close range 
(such as from an inverter fluorescent lamp) hit the projector’s remote sensor, the 
remote control may not function correctly. Adjust the direction of the projector to 
keep light from directly hitting the projector’s remote sensor. 
The remote control works with the projector’s remote sensor.   
 
• The range of the remote sensor is 3 meters with a 60 degree range (30 degrees to 
the left and right of the remote sensor). 
• Also a remote signal reflected in the screen etc. may be available. If it is difficult 
to send a remote signal to the sensor directly, please try. 
• Since the remote control uses infrared light to send signals to the projector 
(Class1 LED), be sure to use the remote control in an area free from obstacles that 
could block the remote control’s output signal to the projector.

About the filter cover for bottom-up use 
WARNING ►Do not replace the filter cover and/or air filter during use or 
immediately after use. Handling while the projector is in a high temperature could 
cause a burn and/or malfunction to the projector. Before operating, make sure that 
the power switch is off, that the power cord is not plugged in, and that the projector 
is cooled adequately. 
When the projector is installed bottom up, please use the accessory filter cover for 
bottom-up use. It is higher than usual filter cover, to keep the space for intake 
ventilation. Please change in the following procedure. 
1. Disconnect all the connectors and adapters that were connected to the projector’s 
ports. Then slowly turn the projector so that the lens-side is facing up. Please be 
careful for a projector not to fall. While the projector is placed lens-side up, hold 
the projector. 
2. Remove the filter cover and the air filter. Hold the knobs while pulling out it.

switch is off, that the power cord is not plugged in, and that the projector is cool 
adequately. 
CAUTION ►If you press the elevator button without holding the projector, the 
projector might crash down, overturn, smash your fingers and possibly result in 
malfunction. To prevent damaging the projector and injuring yourself, always hold 
the projector whenever using the elevator buttons to adjust the elevator feet. 
►Except for inclining by the elevator feet adjustment, place the projector 
horizontally. 
You can use the elevator feet to make adjustments if the surface on which you need

Connecting your devices 
CAUTION  ►Turn off all devices prior to connecting them to the projector. 
Attempting to connect a live device to the projector may generate extremely loud 
noises or other abnormalities that may result in malfunction and/or damage to the 
device and/or projector. 
►Use the accessory cable or a designated-type cable for the connection. Some 
cables have to be used with core set. A too long cable may cause a certain picture 
degradation. Please consult with your dealer for details. For cables that have a 
core only at one end, connect the core to the projector. 
►Make sure that you connect devices to the correct port. Incorrect connection may 
result in malfunction and/or damage to the device and/or projector. 
 
NOTE    • Whenever attempting to connect a laptop computer to the projector, be 
sure to activate the laptop’s RGB external image output (set the laptop 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 computer. 
• Secure the screws on the connectors and tighten. 
• Some computers may have multiple display screen modes. Use of some of these 
modes will not be possible with this projector. 
• For some RGB signal modes, the optional Mac adapter is necessary. 
• When the image resolution is changed on a computer, depending on an input, 
automatic adjust 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. 
About Plug-and-Play capability 
Plug-and-Play is a system composed of the computer, its operating system and 
peripheral equipment (i.e. display devices). This projector is compatible with 
VESA DDC 2B. Plug-and-Play can be achieved by connecting this projector to 
computers that are VESA DDC (display data channel) compatible.   
• Please take advantage of this function by connecting the accessory RGB cable to 
the RGB port (DDC 2B compatible). Plug-and-Play may not work properly if any 
other type of connection is attempted. 
• Please use the standard drivers in your computer as this projector is a
