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.

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.
12
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.

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.
13
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.

Screen Size and Projection Distance
The distance from the lens to the screen determines the actual image size.
The recommended distance and projection distance values given below are
for when the projector is fitted with a standard lens or an optional wide
zoom lens. If the projector has been fitted with an optional lens, refer to the
documentation provided with the lens.
Recommended distance
While referring to the following table, position the projector so that the
images are projected onto the screen at the optimum size. The values
should be used as a guide for setting up the projector. The actual values
will vary depending on projection conditions and the zoom setting.
4:3 screen size (cm (in.)) Projection distance (cm (ft.))
