Document camera images can be stored on memory cards.1Notes
¥ If the ÒScreen sizeÓ in the menu screen 
54
 is set to “Full”, the camera’s full image is
compressed to 1280 x 960 dots before it is stored.  If it is set to “Thru”, only the 1024 x 768
dots at the center of the image are stored.
• The “Camera gain” and “Sharpness” settings are reflected on the images stored on memory
cards; “Contrast” and “Brightness” settings are not.
• It is impossible to store resized or frozen images on memory cards.
• The image data is stored as JPEG format files in the memory card’s “_tlpx” folder.  If there is
no “_tlpx” folder, one is created in the memory card’s root directory.  Stored files are named
“Tlpx001.jpg” to “Tlpx999.jpg”.  If there is already a file named “Tlpx999.jpg” in the folder, no
more images can be stored.
• The size of stored files depends on the content of the image. The number of files that can be
stored on a memory card depends on the size of the files and the amount of free space of the
memory card.
• Do not save the camera image when the memory card is in the write-protect mode.
The memory card may not be accessed.

Notes
¥ When the air filter is dusty, the ventilation is
impaired. This causes the temperature inside the
projector to rise, and may damage the unit.
¥ Attach the air filter cover firmly after the cleaning.
If it is not set correctly, the dusts will enter and
they will be projected and overlapped on the
picture.
¥ If you wash the air filter with water, be sure to let it
dry fully before reinstalling it.  Using it damp will
result in malfunction.
¥ If the air filter is damaged, contact your store of
purchase and replace it with a new one.  Using a
damaged air filter will cause dust or dirt to get
inside the projector and onto the images.
