CONNECTING YOUR DEVICES
Devices You Can Connect to the Projector
(Refer to this section for planning your device
configuration to use for your presentation.)
CAUTION • Incorrect connecting could result in fire or electrical shock. Please
read this manual and the separate “Product Safety Guide”.
ATTENTION Precautions to observe when connecting other devices to the projector
• Whenever attempting to connect other devices to the projector, please thoroughly
read the manual of each device to be connected.
• TURN OFF ALL DEVICES prior to connecting them to the projector. Attempting to
connect a live device to the projector may generate extremely loud noises or other
abnormalities that may result in malfunction and/or damage to the device and/or
projector. Refer to the “Technical” for the pin assignment of connectors and
RS-232C communication data.
• Make sure that you connect devices to the correct port. Incorrect connection may
result in malfunction and/or damage to the device and/or projector.

type cable for the connection. For cables that have a core only at one end,
connect the core to the projector.

USING THE REMOTE CONTROL
Putting batteries into the remote control unit
CAUTION Precautions to observe in regards to the batteries
Always handle the batteries with care and use them only as directed. Improper use may result in
battery cracking or leakage, which could result in fire, injury and/or pollution of the surrounding environment.
• Keep the battery away from children and pets.
•
•
Be sure to use only the batteries specified for use with the remote control. Do not mix new batteries with used ones.
When inserting batteries, verify that the plus and minus terminals are aligned correctly (as indicated in the remote control).
• When you dispose the battery, you should obey the law in the relative area or country.
Remove the battery cover
1
Slide back and remove the battery cover in the direction of the
arrow.
Insert the batteries
2
Align and insert the two AA batteries (that came with the
projector) according to their plus and minus terminals (as
indicated in the remote control).

3
Replace the battery cover in the direction of the arrow and
snap it back into place.

Operating the remote control
• The remote control works with both
the projector's front and rear remote
sensors.
• The range of the remote sensor on
the front is 3 meters with a 90-degree
range (45 degrees to the left and
right of the remote sensor), and back
is 3 meters with a 60-degree range.
• Since the remote control uses
infrared light to send signals to the
projector (Class 1 LED), be sure to
use the remote control in an area free
from obstacles that could block the
remote control's output signal to the
projector.
ATTENTION
Precautions to observe when using the remote control
• Do not drop or otherwise expose the remote control to physical impact.
• Do not get the remote control wet or place it on wet objects. Doing so may result in
malfunction.
• Remove the batteries from the remote control and store them in a safe place if you
won't be using the remote control for an extended period.
• Replace the batteries whenever the remote control starts to malfunction.
• When strong light, such as direct sunlight or light from an extremely close range
(such as from an inverter fluorescent lamp), hits the projector's remote sensor, the
remote control may cease to function. Adjust the direction of the projector to keep
light from directly hitting the projector's remote sensor.

Before replacing the lamp, check the serial number of the replacement lamp bulb (sold separately:
78-6969-9463-7 for MP7640i / 78-6969-9565-9 for MP7740i), then contact your local dealer.
Before replacing the lamp, turn off the power, and unplug the power cord, then wait at least
45 minutes, in order to ensure that the lamp is properly cooled. Removing the lamp bulb while
it is still hot could cause burns, or cause the lamp bulb to burst.
The LCD projector uses a glass lamp bulb. It is a mercury lamp with high
WARNING
internal pressure. High-pressure mercury lamps can break with a loud
bang, or burn out, if jolted or scratched, or through wear over time. Each lamp has a
different lifetime, and some may burst or burn out soon after you start using them. In
addition, when the bulb bursts, it is possible for shards of glass to fly into the lamp housing,
and for gas containing mercury to escape from the projector’s vent holes.
•
•
Handle with care: jolting or scratching could cause the lamp bulb to burst during use.
34
If the replace lamp indicator (see "Related Messages" (
) and "Regarding the
35
indicator Lamps" (
)) comes on, replace the lamp as soon as possible. Using the
lamp for long periods of time, or past the replacement date, could cause it to burst. Do
not use old (used) lamps; this is a cause of breakage.
•
•
•
If the lamp breaks soon after the first time it is used, it is possible that there are electrical problems
elsewhere besides the lamp. If this happens, contact your local dealer.
If the lamp should break (it will make a loud bang when it does), ventilate the room well, and make
sure not to breathe the gas that comes out of the projector vents, or get it in your eyes or mouth.
If the lamp should break (it will make a loud bang when it does), unplug the power cord from
the outlet, and make sure to request a replacement lamp from your local dealer. Note that
shards of glass could damage the projector’s internals, or cause injury during handling, so
please do not try to clean the projector or replace the lamp yourself.
•
Obey local ordinances when disposing of used lamps. In most cases, it is possible to dispose of used
bulbs in the same manner as used glass bottles, but in some cases, bulbs are sorted separately.
• Do not use the projector with the lamp cover removed.

Replacing the lamp
All projector lamps will wear out eventually. If used for long periods of time, the image could become
darkened, and the color contrast could be impacted as well. We recommend that you replace your lamps
early. If the LAMP indicator turns red, or a message prompts you to replace the lamp when you power up

Do not reset the lamp timer without replacing the lamp. Reset the lamp timer always when replacing
the lamp. The message functions will not operate properly if the lamp timer is not reset correctly.
• When the lamp has been replaced after the message of "CHANGE THE LAMP ...THE POWER
WILL TURN OFF AFTER 0 hr." is displayed, or the LAMP indicator is red, complete the following
operation within 10 minutes of switching power ON.
NOTE
• The LAMP indicator is also red when the lamp unit reaches high temperature.
Before replacing the lamp, switch power OFF, wait approximately 20 minutes, and switch power
ON again. If the LAMP indicator is still red, replace the lamp.

• Do not use with air filter cover removed.
• If the air filter becomes clogged by dust or the like, internal temperature rises and could cause
malfunction. The power is automatically turned off in order to prevent the unit from overheating
internally.

OTHER CARE
Caring for the inside of the projector :
In order to ensure the safe use of your projector, please have it cleaned and inspected by
your local dealer about once every 2 years. Never try to care for the inside of the unit
yourself. Doing so is dangerous.
Caring for the lens :
Lightly wipe the lens with a commercially available lens-cleaning wipe. Do not touch the
lens directly with your hand.
Caring for the cabinet and remote control transmitter :
Wipe lightly with gauze or a soft cloth. If soiling is severe, dip a soft cloth in water or a
neutral cleanser diluted in water, and wipe lightly after wringing well. Then, wipe lightly
with a soft, dry cloth.
ATTENTION • Make sure to turn off the power and unplug the power cord before caring for
the unit. Please carefully read "Product Safety Guide" in this manual, in order to care for your
projector correctly.
• Do not use cleaners or chemicals other than those listed above, including benzene and paint
thinner.
• Do not use aerosols or sprays.
• Do not polish or wipe with hard objects.

NOTES
Note 1: Although this message will be automatically disappeared after around 3 minutes, it will be
reappeared every time the power is turned ON.
Note 2: Lamps have a finite product life. Lamps are characterized by the fact that, after long hours of
usage, a lamp will no longer light up, or the lamp will break or burst, etc. This unit is equipped
with an automatic shut-down function, such that the power will automatically be turned OFF
when lamp usage time has reached 2,000 hours. Please be aware, however, that among lamp
types, there are major differences in product lifetimes; a lamp may thus fail to light even prior
to the functioning of the automatic shut-down function of this unit.
