Features of the Projector

Images can be projected regardless of the location.

• The keystone distortion that occurs as a result of the projector being tilted using the front adjustable foot can be corrected. (Automatic keystone correction

p.46)

• The keystone distortion that occurs when projecting from the side of the screen can also be corrected. (Vertical correction and horizontal correction p.47)

• If vertical keystone correction causes the height of projected images to be too short, the height of the projection area can also be adjusted. (Height correction

p.48)

• The Quick Corner function can be used to correct the four corners of the projection area to make the images fit the screen exactly.

p.49

Images can be projected in places without a screen with no loss of original colour. This automatically adjusts image colours to their natural colours even when projecting onto surfaces such as blackboards and partitions. p.51

When something goes wrong with the projector, such as lamp blowing during projection, the projector can notify you of the error via e-mail.

In addition, if you are using EMP-7950, EasyMP allows you to;

• Make easy network connection with a computer via a wireless LAN.

• Project a computer's image over a network.

For instructions on how to use EasyMP, refer to EasyMP Network Setup

Guide and EasyMP Operation Guide.

CAUTION

Be sure to read the Safety Instructions/World-Wide Warranty Terms before handling the batteries.

Rib

TIP

If delays in the responsiveness of the remote control occur or if it does not operate after it has been used for some time, it probably means that the batteries are becoming flat. If this happens, replace the batteries with two new AA alkali batteries.

Before Using the Remote Control

Inserting the Batteries

The batteries are not already inserted into the remote control at the time the projector is purchased. You will need to insert the batteries that are provided with the projector before the remote control can be used.

PROCEDURE

Remove the battery cover.

While pushing down on the rib of the battery cover, slide the battery cover in the direction of the arrow.

Insert the batteries.

Check the positions of the (+) and (–) marks inside the battery holder to ensure that the batteries are inserted the correct way.

Replace the battery cover.

Slide the battery cover in until the tab clicks into place.

Before Using the Remote Control

Using the Remote Control and Remote Operating Range

Using the Remote Control

The remote control is used in the following way.

PROCEDURE

Set the [R/C] switch of the remote control to "ON".

Point the remote control light-emitting area towards one of the remote control light-receiving areas on the projector and operate the remote control buttons.

TIP

• Do not allow sunlight or light from fluorescent lamps to shine directly onto the projector's remote control light-receiving areas, otherwise it may interfere with the reception of signals from the remote control.

• When not using the remote control, set the [R/C] switch on the remote control to "OFF". If you leave the [R/C] switch at "ON", it will consume battery power.

• If a button on the remote control is pressed down for more than 1 minute while the [R/C] switch is at "ON", the signal for that button operation will stop being transmitted (the remote control will change to sleep mode). The purpose of this is to prevent the batteries from being consumed due to something being placed on top of the remote control. When the button is released, normal remote control operation will resume.
