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.

1.1.2 Safety Check after Servicing
Examine the area surrounding the repaired location for damage
or deterioration. Observe that screws, parts and wires have been
returned to original positions, Afterwards, perform the following
tests and confirm the specified values in order to verify compliance with safety standards.
(1) Insulation resistance test
Confirm the specified insulation resistance or greater between power cord plug prongs and externally exposed
parts of the set (RF terminals, antenna terminals, video and
audio input and output terminals, microphone jacks, earphone jacks, etc.).See table 1 below.
(2) Dielectric strength test
Confirm specified dielectric strength or greater between
power cord plug prongs and exposed accessible parts of
the set (RF terminals, antenna terminals, video and audio
input and output terminals, microphone jacks, earphone
jacks, etc.). See Fig.1-1-11 below.
(3) Clearance distance
When replacing primary circuit components, confirm specified clearance distance (d), (d') between soldered terminals, and between terminals and surrounding metallic
parts. See Fig.1-1-11 below.

1.2INSTALLATIONS
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 40 to 200(wide side) inches diagonal (16:9), requiring a projection distance of 1.58m to 8.03m (wide 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.
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. 6.2kg) 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
