SECTION 1

PRECAUTION

1.1 SAFTY PRECAUTIONS

Prior to shipment from the factory, JVC products are strictly inspected to conform with the recognized product safety and electrical codes of the countries in which they are to be sold.However,in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced.

1.1.1 Precautions during Servicing

(1) Locations requiring special caution are denoted by labels

and inscriptions on the cabinet, chassis and certain parts of the product.When performing service, be sure to read and comply with these and other cautionary notices appearing in the operation and service manuals.

(2) Parts identified by the symbol and shaded ( ) parts

are critical for safety. Replace only with specified part numbers.

NOTE :

Parts in this category also include those specified to comply with X-ray emission standards for products using cathode ray tubes and those specified for compliance with various regulations regarding spurious radiation emission.

(3) Fuse replacement caution notice.

Caution for continued protection against fire hazard. Replace only with same type and rated fuse(s) as specified.

(4) Use specified internal wiring. Note especially:

• Wires covered with PVC tubing

• Double insulated wires

• High voltage leads

(5) Use specified insulating materials for hazardous live parts.

Note especially:

• Insulation Tape

• PVC tubing

•Spacers

• Insulation sheets for transistors

•Barrier

(6) When replacing AC primary side components (transformers,

power cords, noise blocking capacitors, etc.) wrap ends of wires securely about the terminals before soldering.

Consequently, when servicing these products, replace the cathode ray tubes and other parts with only the specified parts. Under no circumstances attempt to modify these circuits.Unauthorized modification can increase the high voltage value and cause X-ray emission from the cathode ray tube.

(12) Crimp type wire connectorIn such cases as when replacing

the power transformer in sets where the connections between the power cord and power trans former primary lead wires are performed using crimp type connectors, if replacing the connectors is unavoidable, in order to prevent safety hazards, perform carefully and precisely according to the following steps.

• Connector part number :E03830-001

• Required tool : Connector crimping tool of the proper type which will not damage insulated parts.

• Replacement procedure

a) Remove the old connector by cutting the wires at a

point close to the connector.Important : Do not reuse a connector (discard it).

cut close to connector

Fig.1-1-3

b) Strip about 15 mm of the insulation from the ends

of the wires. If the wires are stranded, twist the strands to avoid frayed conductors.

15 mm

Fig.1-1-4

c) Align the lengths of the wires to be connected. In-

sert the wires fully into the connector.

Metal sleeve

Fig.1-1-1

(7) Observe that wires do not contact heat producing parts

(heatsinks, oxide metal film resistors, fusible resistors, etc.)

(8) Check that replaced wires do not contact sharp edged or

pointed parts.

(9) When a power cord has been replaced, check that 10-15

kg of force in any direction will not loosen it.

Power cord

Fig.1-1-2 (10) Also check areas surrounding repaired locations. (11) Products using cathode ray tubes (CRTs)In regard to such

products, the cathode ray tubes themselves, the high voltage circuits, and related circuits are specified for compliance with recognized codes pertaining to X-ray emission.

1.2 INSTALLATIONS

1.2.1 Installation method

The D-ILA system (reflecting type active matrix liquid crystal system) does not require convergence adjustment. Note the following when placed on a floor (refer to OPERATING INSTRUCTIONS for actual operating method).

(1) Place the projector at the position needed for the required image size observe the projector is not tilted horizontally.

[The image size is 37 to 275(wide side) inches diagonal (16:9), requiring a projection distance of 2m to 12m (tele side).] (2) Adjust the placement site and screen tilt so that the projection angle is perpendicular to the screen. (3) Adjust the placement site and screen position (height) so that the projection lens center is at the lower edge of the screen. (4) Project an image on the screen. (Connect video equipment and power source, switch power on and select the input.) (5) Fine adjust the projected image position and angle. If adjusting the placement site and screen cannot correct the projected po-

sition (too low) or angle (lower part of image widened), adjust the front foot. (6) Turn the lens ZOOM ring by hand and adjust for suitable image size. (7) Turn the lens FOCUS ring by hand and adjust to correct image blur. (8) Adjust [KEYSTONE] if the image appears expanded or contracted at the top or bottom edge. (9) Adjust < Image adj. > - [Brightness], [Contrast], [Sharpness], [Color] and [Tint] for optimum picture.

1.2.2 Installation site and status

• The projector contains a fan for cooling. Obstruction of the ventilation openings can lead to internal overheating, abnormal operation and failure. Also observe there is plenty of free space between the projector and adjacent walls, ceiling and other equipment. Note that excess heat can cause failure and damage to both the projector and nearby equipment.

Required spacing :

Front = 15cm / left and right sides = 30cm / rear = 50cm (When the unit is enclosed with block according to the required spacing on the left side, provide the unit with adequate ventilation so that the temperature inside of the enclosed area is kept at the same temperature in the open space in the room.)

• Avoid locations that are wobbly or inclined. If the setting site floor has protrusions or horizontal cannot be maintained, there is risk

the projector may drop, fall over, etc. If located in a site where left to right tilt is greater than ±5° and front to rear tilt greater than ±20°, particularly the optical system components can be severely affected and there is risk basic performance and quality of the

projector cannot be maintained.

• Observe the site can stably bear the weight (approx. 6kg) of the projector over a long period of time.

• If mounted on a stand with casters, observe the casters are securely braked to prevent movement.

• Avoid suspending in a location subject to vibration. Both the projector and mounting fixture can be damaged.

• Do not place in the following types of locations. Especially, Avoid locations subject to dust, grit, smoke or other airborne contaminants. Use adequate caution when providing external ventilation, filters and dust protection.

 Near water or in humid sites  Near heaters or heat generating equipment  Dust or grit  Direct sunlight  Oily or tobacco smokes  Very high or very low temperature

2.3 PROJECTION SPECIFICATIONS AND NOTES

2.3.1 Projection distance

• The usable projection distance (focus obtainable) is tele side : approx. 2m to 11.5m / wide side : approx. 1.6m to 12m. The picture size (16:9) is 37 to 275 inches.

• Use the wide side for sizes bigger than 200 inches.

• If picture edge distortion occurs at the minimum distance (1.6m), increase the distance slightly.

• The guaranteed projection distance range is from 2m to 10m.

2.3.2 Projection image and image size

• The projection distances and image size relationship given in the operation manual is approximate for general reference. The actual values may vary due to lens tolerance and other factors.

• A distance between a horizontal line that passes a center of the projection lens of this model and a bottom of the projection screen is one-thirtieth of the vertical size of the screen. (See the Instruction Manual.)

• The projector a horizontal (vertical line) "keystone (trapezoid distortion)" due to projection angle wavering corrective function. Keystone compensation yields a smaller image than the uncompensated picture. When the image is important, to the extent possible, correct by selecting the projector position, screen front to rear tilt and projection angle (perpendicular) to the screen.

2.3.3 Other cautions

• Use care not to directly touch the lens. Clear soiling from the lens with optical lens paper or a photographer's blower.

• Check the lens cap is removed before projecting. If left installed the projector can overheat and the lens cap can be deformed.

• Sunlight or other illumination can render the image difficult to see. Use a curtain or other means to shield the screen from stray light.

2.4 CONNECTION AND OPERATION CAUTIONS

• The projector can function with fH 15 to 120 kHz, fV 24Hz, 25Hz, 30Hz, 50Hz to 120 Hz signal input, but even within this range, partial picture loss, fold-over at the top and bottom picture edges and other effects can occur according to signal type and conditions to prevent a normal projected image (see "Signals that can be input the projector" of the OPERATING INSTRUCTION).

• The projector is compatible with UXGA input (H : 1600 ~ V : 1200 dots).

• VGA computer signal may be detected and displayed as 480p mode of the video system. Select the video system input at the menu.

• If the video signal from a VTR or other source contains a large jitter component, distortion, blurring or instability can occur in the picture. In this case, use a TBC (time base corrector) or video equipment (e.g., VTR) that contains a TBC.

• The digital zoom and still picture (freeze) functions do not operate with UXGA signal input. When these functions are desired, use another signal input.

• The menu indication differs when the input is selected for video system or computer system. See below.
