Loading Batteries into the Remote Control
Please load batteries into the remote control. Once the remote control starts to work erratically, replace the batteries.
Controls and Features
1.Open the back cover
Push the hook on the back cover lightly in the direction of
the arrow and lift it up.
2.Load the batteries
Place the two supplied batteries (AA/R6-size) into the re-
mote control as illustrated below. To prevent short circuit,
be sure to insert the minus · end of the battery first.
3.Close the back cover
Close the back cover by inserting the end first and press-
ing down until a click is heard.
Precautions for using batteries
If batteries are used incorrectly, they may crack or leak.
This could cause fire, burn, malfunction, 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 are differ-
ent in characteristics.
•Place batteries so they match the polarities indicated on
the cartridge.
•Be sure to insert the minus 
· end in first to avoid short-
circuiting.
•Do not put batteries into a fire or try to recharge them.
•Use only designated batteries.
•Remove the batteries if the remote control is not to be
used for a prolonged period.
Battery Life
Batteries run for six months to one year in normal use. How-
ever, the batteries supplied are for confirming operation and
may not run that long. When the remote control starts fail-
ing to work properly, replace the batteries with new ones.
Battery Leakage
When the batteries are totally exhausted and can no longer
be used, replace them immediately.
Leaving the batteries in the battery compartment causes
battery leakage which in turn causes malfunction.
Further, in cases where the leakage comes to contact with
the skin, wipe it away with a cloth, otherwise skin problems
may occur.

Precautions for Installation
Installing the Projector
Please read the following properly when installing the projector.
Installation Environment
Please do not install or use this projector in the follow-
ing places as it is a precision device. This could cause
fire or a malfunction.
•Where there is water, humidity or dust.
•Where the projector may be subjected to oil, smoke or
cigarette smoke.
•On a soft surface such as a carpet or cushion
•Where the projector may be subjected to direct sunlight.
•Where temperature is high or low.
Allowable operation temperature range : +5˚C to +35˚C
Allowable relative humidity range : 20% to 80%
(no condensa-
tion)
Allowable storage temperature range : –10˚C to +60˚C
•Any room in which there is smoke and grease.
Even where smoke and grease level is minimal, prolonged
exposure would affect the projector.  The projector emits
heat and cools the optical components down by taking in
large amount of air.  When the optical path is soiled by
grease/dirt, images become dark and color projection de-
teriorates, such often being the cause of damage. Re-
moving grease/dirt totally from the optical parts is not pos-
sible.
Precaution for Usage
This projector uses a light-source lamp which becomes
high in temperature when projecting.
Please DO NOT use it in the following ways as it may
result in fire or malfunction.
•Lay the projector on its side when projecting.
•Project outside the specified angle.
Do not use the projector while it is set more than ±5˚
horizontally (left/right), or more than ±25˚ vertically (up/
down). This could cause color variation or shorten the
lamp life.
•Block the exhaust vents.

Adjusting the Inclination of the Projector
The vertical angle and leveling of the projector can be adjusted with the adjustable feet at the bottom of the projector.Do not use a cover which may enclose the projector
air-tight or block the exhaust vents. Allow sufficient
space around the projector. When the projector is en-
closed in a space of the following dimensions, use an
air conditioner so that internal and external tempera-
tures are the same.
Adjusting the vertical angle of the projector
While pushing the lever upward, raise the projec-
tor. The maximum extension is approximately
31mm. To retract the foot, push the lever and lower
the projector slowly; the projector is fixed at the
position where you release the lever.
Adjusting the level of the projector
Lift the projector, rotate the front adjustable foot,
and adjust the horizontal angle until the projector
is level.

●Trapezoidal-distortion can be corrected using the KEYSTONE
button on the projector. (
☞ page 30)
Up to approximately 30˚ upward
and downward from the horizon-
tal line.Up to approximately 10˚ upward and
downward from the vertical line.
Mounting the Projector
When mounting of the projector is required, do it using the embedded three screw holes (M6 nuts) at the bottom of the projector.
Precaution for ceiling-mount
•To ceiling-mount and adjust the projector, special exper-
tise and techniques are necessary. Be sure to ask your
dealer or specialist to perform the work.
•Do not mount on places that will be subjected to knocks
and vibrations.
•As the depth of the screw holes is 10mm, use screws
shorter than 10mm but longer than 6mm. Otherwise, the
screws will damage the internal parts of the projector
causing malfunction. 
						

							17
Projection Distance and Screen Size
•This projector uses 1.3x manual zoom lens for projection.
•The range of projection for good focus is approximately 1.6m to approximately 12m when the aspect ratio of the screen is 4:3.
Install the projector within this range.
•If the KEYSTONE is adjusted, the screen becomes smaller. (☞ page 30)

Effective Range and Distance of the Remote Control Unit
When the remote control unit fails to work properly
•When the batteries in the remote control unit are exhausted, improper functioning would occur.  Please replace with new
batteries.
•When either the remote control unit or projector alone is connected to the remote cable, the connected side will not be able
to work. Please check the cable connection. The operable distance of the remote control unit is about 7m for direct reception. The remote control unit can be used by having the
transmission signals reflected by the screen. In this case, please set the total distance (distance between projector and screen,
A  and distance between remote control, B) of “A + B” within 7m. The operable angles of the remote control unit are 30˚ right
and left, and 20˚ up and down.

 Using as a wireless remote control unit
As the effect of signals reflected from the remote control unit differ with the type of screen used, effective range and distance
may decrease.

 Using as a wired Remote Control
By connecting a separately sold remote control (RM-M3010) and cable (about 3m: QAM0081-001/ 15m: QAM0247-001) to the
REMOTE terminal, the remote control can be used as a wired control unit. When connected to the cable, the remote control’s
transmitter and the projector’s sensor would not function. Please keep within the range of the remote cable length. Warranty is
not extended to the case where an extension cord is used.
❈The ESCAPE button on the separately sold remote control (RM-M3010) is equivalent to the EXIT button on the supplied
remote control unit. There is no equivalent to the H, V-KEYSTONE and FOCUS buttons found on the supplied remote control.
