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.
1 Remove the battery cover Slide back and remove the battery cover in the
direction of the arrow.
2 Insert the batteries 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 Close the battery cover Replace the battery cover in the direction of the
arrow and snap it back into place.

30 degrees 30 degrees 45 degrees 45 degrees
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.

THE LAMP
HIGH VOLTAGE HIGH TEMPERATURE HIGH PRESSURE
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. · If the replace
lamp indicator (see “Related Messages” ( 34 ) and “Regarding the indicator
Lamps” ( 35 )) 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.
29
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 the projector, the lamp needs to be replaced. (See “Related Messages” ( 34 ) and “Regarding the Indicator Lamps” ( 35 ) for details.)

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

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.
