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).  
Close the battery cover  
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 projectors 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 projectors 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  
34  
the projector, the lamp needs to be replaced. (See "Related Messages" (  
) and "Regarding the  
35  
Indicator Lamps" (

ATTENTION Make sure that the screws are screwed in firmly. Loose screws could result in damage or injury.  
Do not use with lamp cover removed.  
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.

THE AIR FILTER  
Caring for the air filter  
The air filter should be cleaned about every 100 hours. If the LAMP indicator and  
TEMP indicator blink red simultaneously, or a message prompts you to clean the air  
filter when you turn on the unit, the filter needs to be cleaned. (See "Related

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.
