1.1 Development Objectives

We believe the demand in the market for 1500-2500 lumen XGA models is sure to

expand, and the demand for 1500-1999 lumen SVGA models will remain constant.

Using our proprietary optical expertise, Canon has developed three very competitive
products, featuring outstanding illumination and compact, micro-portable class design.
The three models share a common design and many common parts to contain
development cost while reinforcing and adding flexibility to the line-up to better meet
customer needs and increase our competitive position in the marketplace.

1) The LV-7215/LV-7210 expand the projector product line-up, increasing our
presence in the "volume zone" in response to demand.

2) The LV-5210 replaces the LV-5200 in the line-up and will build on the LV-5200's
share.

With this expanded line-up, our market strategy is to capture an even larger share of

the expanding projector market.

1.2 Product Outline

The LV-7215 is 2500 ANSI Lumen XGA model, and the LV-7210 is ANSI 2000 lumen
XGA model. The LV-5210 is 2000 lumen SVGA model and all three weigh 2.9kg and are
"micro-portable" models.

This newly designed wide-angle, class-leading high magnification (1.6×) lens allows
projecting a 100-inch image at a distance of only 2.5 meters.

Part 1: General Information

1-1

Moreover, the DVI video interface allows crystal-clear digital signal input from a DVD,
and new progressive scan circuitry converts interlace video to clear progressive scan
video.

Depending on conditions, the lamp mode can be switched. With the reduced
brightness, the fan runs at optimum speed giving a 35dB silent mode, and the "auto
mode" assures detail even in the blacks of dark scenes.

In addition to the Media Card Imager LV-MC01, the new Multi Card Imager LV-MI01
with additional LAN (Wired or wireless) functions is optionally available.

The remote control for these models is a new compact, lightweight design featuring a
laser pointer to improve your presentations.

3.4 Mechanisms and System

● Lamp Mode Selection

The lamp current can be selected.

* The LV-5210 uses a 200W lamp, but it is limited as shown to reduce heating.

Normal mode gives priority to brightness. It is used in large halls, or rooms with
high ambient light.
Silent Mode uses reduced power giving lower brightness and heat output so the
cooling fan speed can be slowed to lower noise level.
Silent Mode is appropriate when screen size is small and the quantity of light is
sufficient.
In Auto Mode, lamp output is controlled according to brightness of the image, so dark
areas can be emphasized when dark scenes appear in movies.

● Standby Mode Setting

The function sets the standby current.

• Normal: Normal standby current

• Economy: Lowered standby current (During standby, the power on signal from the

LV-MI01 is not accepted.)

● Adjustable Feet

Adjustable feet are on the front bottom of the main unit on the projection lens side.
These feet set the projector at an incline, enabling projection at an angle. A maximum
angle of 11.9_ can be set between the projector's optical axis and the table on which
the projector rests.
With one touch, the lock on the adjustable feet can be released and the feet stored
inside the main unit.

* Keystoneing introduced by the tilt is digitally compensated.

● Sound Muting

The sound can be turned off.

* A 1W speaker is installed. The audio from the PC or video is played monaurally.

5. DESCRIPTIONS

5.1 Optics

The lens is a newly designed wide zoom lens, LCD panels with a large aperture ratio
of 0.79" (0.80" for publication) and a 200 Watt UHP lamp giving as very bright image
from a compact package.

● 1.6× Wide Zoom Lens

This newly designed class-leading 1.6X wide-angle zoom lens is composed of 11 air­spaced elements in six-group -++-++ configuration.
It has two aspherical lenses (G2, G10), aspheric on both sides, allowing reduction of
the front lens diameter and reduction of the total number of elements. An anomalous
dispersion element (G9) suppresses color aberrations. The result is very high image
quality.
With the longest zoom ratio in the class, this compact lens allows projection of large
images at close distances with beautiful high resolution and very low color smear.
Only environmentally friendly lead-free glass is used in the lens.

● Projection Screen Size

These models produce a high-quality 100-inch image at a throw of only 2.5 meters.
The projection distance and screen size relationship is shown in the table below.

* The correct screen size is from 40 to 300 inches. Image quality outside this range is not guaranteed.

● LCD Panel

These models use a 20mm (0.79") diagonal LCD panel. This super high aperture ratio
type panel gives improved brightness and contrast.

● Lamp

The projection lamp is a small but bright 200-watt UHP lamp.
The arc* in this lamp is a very short 1mm, the shortest in the 200W class. Combined
with the excellent design of the reflector results in a very compact lamp.
In the LV-5210, which uses the SVGA panels, the output is limited to 185 watt to
achieve the best balance between illumination, heat transfer, and current
consumption.

* Arc length: When the arc length is shortened, the parallel light output increases.

Since there is less light scatter (diffusion), the reflector size can be reduced.

5.2 Image

● Progressive Scan

By utilizing the "scan Converter IC" to it fullest, the image and progressive scan are
improved.

* Compared to the LV-7555, the progressive functions are limited.

● Start-up Display Customizing (Logo capture)

In these models the portion of the flash memory is reserved for "logo capture", making
it possible to save any image as data for use as the start-up screen.

5.3 Video Signal

Because of the compact design of these models, the number of connectors has been
reduced and given multiple functions. The user can select the correct signal on the
settings screen.

5.4 Mechanisms and System

These models were designed to be smaller, lighter, but brighter than previous models.

Layout and connector placement were thoroughly reconsidered resulting in a
significant reduction. These new models are less than 70% the size of the LV­7355/7350/5200 series.

The LV-7215/7210/5210 share identical layout and as many parts as possible to
reduce development and production cost.

● Heat and Noise Reduction

Special consideration was paid to preventing heat build-up in its compact confines.
Normally, many interior parts are coated with black nickel, which absorbs heat easily
causing heat buildup from the light absorbed. With these new models, the aluminum
surrounding the bulb has a thermal coating so the black nickel parts do not absorb
much heat.
Furthermore, by optimizing the exhaust fan airflow, very quiet (35dB) operation is
possible in Silent Mode.

* When temperature is low, automatic fan control reduces the exhaust fan's speed and

fan noise is reduced as in earlier models.

● Lamp Modes

As in the LV-7555, these models have three lamp modes:
In Silent mode the noise level and brightness is controlled as follows.

Auto Mode controls the brightness so dark areas in scenes are not lost.

5.5 Design

The design concept of Canon's multimedia projectors is a 3-dimensional form, which
has the precise, tension look of an optical apparatus-likeness is inherited. Furthermore,
the design gives a sociable light impression which is simple and has a transparent
feeling.

● Styling

The styling of these models is equally well suited for the private living room, the
modern office, or a retail outlet.
The body is designed with simple curves flowing into clean surfaces, the so-called "air
style form".
Moreover, the transparent, "jelly-bean" style operation panel serves as an accent
point. The surface treatment and a key layout are designed so the machine can be
operated easily in the dark.

● Coloring

The new Frosty White Pearl coloring has a luxurious transparent look not found in
earlier models. Unlike earlier models, which had a single coat of paint on the body,
these models have a completely different texture by using two coats, a transparent
topcoat layer over the base coat. This gives a completely different feeling than early
models.
In addition, painting is carried out in an automated clean room, which allows very
strict control of the coating thickness.

● Detail

The ring around the outside of the lens protects the optical engine from shock and
could prevent your presentation from being stopped by an unexpected accident.
Moreover, in order to keep exhaust heat and fan noise away from people and to realize
comfortable use environment, the exhaust port was put at the side of the lens.
Furthermore, punched metal covers are used for the exhaust port, air intake, and
speaker instead of the conventional blind-like louvers.
Connectors required for the user interface are arranged in the back, and options,
such as a multi-card imager, are easy to understand and user friendly.
In addition, the remote control uses luminescent material for the buttons and a
mirrored base under them making it is possible to perform exact operations even in
very dim lighting.

1. SAFETY INSTRUCTIONS

The following precautions must be observed during servicing and inspection.

Observe all safety precautions.

Comply with all caution and safety-related notes provided on the cabinet back, cabinet
bottom, inside the cabinet, on the chassis or components, as well as the precautions
shown in the instruction manual during servicing.

Avoid electric shock.

Since an AC voltage is applied to the chassis for the set, touching the chassis during
power-on may cause electric shock. When service is performed during power on, use an
insulation transformer, wear protective gloves, and remove the plug during parts
replacement. As there are high-voltage areas inside the projector, handle it with care
when the power is on.

Use specified parts.

The parts of the set have safety properties, such as inflammability and voltage
withstand. Therefore, use replacement parts with the same characteristics as the
original ones. The critical components for safety are indicated by mark in the schematic
diagram and parts list must be replaced by the recommended parts.

Reinstall parts and wires in their original positions.

Insulating materials, such as tubes and tape, are used and some components are
installed over a PC board for safety. Reinstall internal wires with clamps so that they do
not touch any heat-generating or high-voltage parts.

Safety c

heck after service

Verify that service locations are not deteriorated and all removed screws, parts and
wires are installed in their original positions. In addition, perform the following test to
ensure safety.

Insulation resistance test method

Remove the plug from the electric outlet and press the power switch. Using a 500V
insulation resistance tester (or a multimeter if any insulation resistance tester is not
available), check that the insulation resistance between each terminal of the plug and
external exposed connector (external speaker connector, remote control connector, AV
input/output connector, etc.) is 1Mohm or higher

. If not, the set must be inspected and

repaired.

Components indicated by mark in the parts list and the schematic diagram designate components in
which safety can be of special significance. It is, therefore, particularly recommended that the
replacement of there parts be made by exactly the same parts. Using unspecified parts may worsen
failure or cause fire or electric shock.

Eye damage may result from directly viewing the light produced by the lamp used in this equipment.
Always turn off the lamp before opening the cover.
Never turn the power on without the lamp to avoid electric shock or damage of the devices since the
stabilizer generates high voltages (15kV - 25kV) at its starts.
Since the lamp is very high temperature during units operation replacement of the lamp should be done at
least 45 minutes after the power has been turned off, to allow the lamp cool-off.

2. CIRCUIT PROTECTIONS

This projector provides the following circuit protections to operate in safety. If the
abnormality occurs inside the projector, it will automatically turn off by operating one of
the following protection circuits.

2.1 Fuse

A fuse is located inside of the projector. When the
POWER indicator is not lightning, the fuse may be
opened. Check the fuse as following steps.
The fuse should be used with the following type;

[Fuse replacing steps]

1. Remove the cabinet top and cabinet front following

to “Mechanical Disassemblies”.

2. Replace the new one with the specified type.

2.2 Thermal Switch

There is the thermal switch (SW902) inside of the
projector to detect the internal temperature rising
abnormally. When the internal temperature reaches
near 90˚C, it cuts off the AC main power supply.

The thermal switch cannot be reset itself
automatically even if the internal temperature
becomes normal. Reset the thermal switch following

2.4 Warning Temperature and Power Failure Protection

The projector will be automatically turned off when the internal temperature of the
projector is abnormally high, or the cooling fans stop spinning, or the power supplies in
the projector are failed.

• If the WARNING indicator is flashing, it may detect the abnormal temperature inside

the projector. Check the following possible causes and wait until the WARNING
indicator stops flashing, and then try to turn on the projector.

• If the WARNING indicator lights red, it may defect the cooling fans or power supply

circuits. Check fans operation and power supply lines referring to the chapter “Power
supply & protection circuit” in the Chassis Block Diagram section.

[Possible causes]

• Air filters are clogged with dust particles. Remove dust from the air filters by following

instructions in the “Air filter care and cleaning” below.

• Ventilation slots of the projector are blocked. In such an event, reposition the

projector so that ventilation slots are not obstructed.

• Check if projector is used at higher temperature place (Normal operating temperature

is 5 to 35˚C or 41 to 95˚F)

2.5 Air Filter Care and Cleaning

The removable air filter prevents dust from accumulation on the surface of the
projection lens and projection mirror. Should the air filter become clogged with dust
particles, it will reduce the cooling fan’s effectiveness and may result in internal heat
build up and reduce the life of the projector.

To clean up the air filters, follow the cleaning
procedure below:

1. Turn the power off, and disconnect the AC

power cord from the AC outlet.

2. Turn the projector up side down and remove

air filters by pulling the latches of it upward.

3. Clean the air filters with brush or wash out

the dust and particles.

4. Replace the air filters properly. Make sure

that the air filters are fully inserted.
