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.

Power Management
The power management function can be set so that the lamp automatically turns off if no image signals have been input for a set time and the projector has also not been operated. The time can be set between 1 and 30 minutes. The initial setting is ON, and either ON or OFF is set according to a setting screen. This power-management status will automatically be released when image signals are again input or the projector has again been operated. (The 90-second cooling operation that occurs directly after shutting off will not be released.)
Graphical User Interface
Pressing the MENU button will display a menu bar on the screen. The user can make various settings on the screen. The display can be shown in one of twelve languages: English, German, French, Spanish, Italian, Portuguese, Dutch, Swedish, Chinese, Korean, Russian or Japanese.

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.

2.4 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.
