Projector features
This projector is used to project various computer signals as well as NTSC / PAL 
/ SECAM video signals onto a screen. It requires just a little space for installation 
and gets a large image from short distance.
 High Brightness
Newly developed 165W UHB (Ultra High Brightness) lamp gives you a higher 
brightness image on a screen. The image can be still kept as bright and clean 
enough for use in bright rooms.
 Low Noise
WHISPER mode is equipped for reducing acoustic noise to realize quieter 
operation. It is perfect for use in low luminance rooms where low noise is more 
important than brightness.

Even with its many features, this projector is extremely compact and slim, 
which gives you more flexibility and usability to use it where you want.

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.

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 allow a battery in a fire or water. Keep batteries in a dark, cool and dry 
pla ce.

Preparations
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.
