Install batteries in the remote control. If the remote control has started to work erratically, replace the batteries.

Open the back cover.

Open the back cover in the direction of the arrow.

Install the batteries.

Place the two supplied batteries (AA/R6-size) in the remote control as illustrated below.

Precautions for using batteries

If batteries are used incorrectly, they may crack or leak liquid. This could cause a fire, burn, malfunction, or staining or damaging of the surroundings.

Beware of the following:

• Do not mix new and old batteries.

• Do not mix different types of batteries as they differ in

characteristics.

• Place batteries so they match the polarities indicated: (+) to (+) and (–) to (–).

• Be sure to put the minus (–) end in first to avoid short-circulating.

• Use only designated batteries.

• Remove the batteries if the remote is not to be used for a

prolonged period.

• When the batteries are exhausted, replace them immediately. Otherwise, liquid could leak, or malfunction could occur due to leaking liquid. If the leaked liquid contacts the skin, wipe it off with a cloth, otherwise the skin could become rough.

• Do not put batteries into a fire or try to recharge them.

• Batteries run for six months to one year in normal use.

However, the batteries supplied are for confirming operation and may not run that long. When the remote control starts failing to work properly, replace the batteries with new ones.

Close the back cover.

First fit the claws on the back cover in the case, then close the back cover in the direction of the arrow.

Projection Distance and Screen Size

• The range of projection distances that can be focused depends on the lens unit (optional) to be used. When the aspect ratio of the screen is 4:3, the range is as follows and you need to install the projector within this range.

Lens type GL-M2910G 0.77 m to 4.03 m GL-M2915SG 1.76 m to 4.50 m GL-M2920ZG 2.77 m to 19.71 m GL-M2930SZG 4.74 m to 29.87 m *: The value for projection distance is a guide (reference) one. The projected image size may vary depending on the

manufacturing tolerance of the projection lens.

Notes

• For detailed relationship between projection distances and projection screen sizes, refer to Appendix A. The relationships for both 4:3 and 16:9 ratios are listed there.

• When installing a screen, use a 4:3 aspect-ratio picture.

• (A 16 : 9 aspect-ratio picture is projected based on the width of the range in which a 4:3 aspect-ratio picture is projected.)

• The diagonal length of a 16:9 aspect-ratio screen is about 91.8% that of a 4:3 aspect-ratio screen. This value is only a guide

(reference).

• If sunlight or lamp light strikes the projection screen directly, the picture tends to become pale and dim. Use a curtain or other means to shield the light.

• Set the projector horizontally on a surface that is within the range of adjustable angles (up/down adjustment angle: +7° ; horizontal adjustment angle: ±1.5°).

• If the keystone is adjusted, the projected screen becomes smaller.

• When hanging from the ceiling, use a dedicated hanging fixture (not supplied).

■ Optional Lenses

This projector does not include a lens. You can select one of the optional lenses to adjust the projection distance. Please ask your authorized dealer or service center to install the lens.

Setting the Position Selecting Screw for Ceiling Mounting

When using the projector in an upside-down, ceiling-mounted position (inverted top-to-bottom and right-to-left), the “position selecting screw for ceiling mounting” must be turned to switch to ceiling mounting. This will correct variance in color images (shading), which otherwise would occur in ceiling mounting. To revert to normal desktop setting, turn the “position selecting screw for ceiling mounting” back to the initial position (factoryshipped).

When using the projector in an upside-down, ceiling-mounted position:

Turn the “position selecting screw for ceiling mounting” fully counterclockwise (until it is turning idly).

To again use the projector in a normal desktop setting:

Turn the “position selecting screw for ceiling mounting” fully clockwise (until it firmly tightens).

For normal desktop mounting:

Turn the screw clockwise.

For upside-down, ceiling-mounting:

Turn the screw counterclockwise.

CAUTIONS

•To ceiling-mount and adjust the projector, special expertise and technique are necessary. Be sure to ask your dealer or a specialist to perform this work.

•To turn the “position selecting screw for ceiling mounting”, use a Phillips screwdriver with a 30-mm or longer shank. The screw is located in the hole shown in the illustration.

Position selecting screw for ceiling mounting

Note

• When using the projector in a ceiling-mounted position, you should reverse the projected image by changing the settings of Right Left rev. and Top Bottom inv. menus. For details, refer to page 54.

Horizontal scanning frequency 15kHz - 105kHz

Vertical scanning frequency 50Hz - 100Hz

Be sure that the computer to be used suffices the following conditions:

• The computer has the video signal output port. Be sure that the computer has the video signal output port by reading the instruction book of the computer. The video signal output port is generally called as “RGB port”, “monitor port”, or “video port”. If the computer-monitor hybrid type or note type is used, it may need to prepare for an external output port. Also, there will be the type to which an external output port cannot be installed.

• DVI input During DVI input, depending on the computer settings, there may be no signal input or an error may occur (blue screen). If this happens, turn off the power to both the projector and the computer, and then turn the projector back on before turning the computer on again. Then correctly set the computer's graphic board.

• The resolution and the scanning frequencies are within the range specified in the table on page 23. Be sure that the resolution and the scanning frequencies of the video signal are within the range. A video signal out of range cannot be used. (Even signals out of the range could be projected. However, it may not sharp enough. On the other hand, even some of the signals within the range may require adjustment depending on the video board used.) When a signal other than listed in the table on page 23 is input, the image could be partially erased or an unneeded fold-over image could appear. Even signals in the frequency range that can be input may not be displayed normally depending on the type of the signal.
