SECTION 1
PRECAUTION
1.1 SAFETY PRECAUTIONS
Prior to shipment from the factory, JVC products are strictly in-
spected to conform with the recognized product safety and elec-
trical 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 spu-
rious radiation emission.
(3) Fuse replacement caution notice.
Caution for continued protection against fire hazard.
Replace only with same type and rated fuse(s) as speci-
fied.
(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.
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.
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 volt-
age circuits, and related circuits are specified for compli-
ance with recognized codes pertaining to X-ray emission.
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 cir-
cuits.Unauthorized modification can increase the high volt-
age 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 be-
tween the power cord and power trans former primary lead
wires are performed using crimp type connectors, if replac-
ing the connectors is unavoidable, in order to prevent safe-
ty 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 re-
use a connector (discard it).
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.
Fig.1-1-4
c) Align the lengths of the wires to be connected. In-
sert the wires fully into the connector.
Fig.1-1-5
d) As shown in Fig.1-1-6, use the crimping tool to
crimp the metal sleeve at the center position. Be
sure to crimp fully to the complete closure of the
tool.

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 compli-
ance with safety standards.
(1) Insulation resistance test
Confirm the specified insulation resistance or greater be-
tween power cord plug prongs and externally exposed
parts of the set (RF terminals, antenna terminals, video and
audio input and output terminals, microphone jacks, ear-
phone 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 spec-
ified clearance distance (d), (d') between soldered termi-
nals, and between terminals and surrounding metallic
parts. See Fig.1-1-11 below.
Fig.1-1-8
(4) Leakage current test
Confirm specified or lower leakage current between earth
ground/power cord plug prongs and externally exposed ac-
cessible parts (RF terminals, antenna terminals, video and
audio input and output terminals, microphone jacks, ear-
phone jacks, etc.).
Measuring Method : (Power ON)Insert load Z between
earth ground/power cord plug prongs and externally ex-
posed accessible parts. Use an AC voltmeter to measure
across both terminals of load Z. See Fig.1-1-9 and follow-
ing Fig.1-1-12.
Fig.1-1-9
(5) Grounding (Class 1 model only)
Confirm specified or lower grounding impedance between
earth pin in AC inlet and externally exposed accessible
parts (Video in, Video out, Audio in, Audio out or Fixing
screw etc.).Measuring Method:
Connect milli ohm meter between earth pin in AC inlet and
exposed accessible parts. See Fig.1-1-10 and grounding
specifications.

1.4 INSTALLATIONS
1.4.1 INSTALLATION METHOD
This projector comes with the D-ILA system (reflecting type ac-
tive matrix liquid crystal system) that does not require conver-
gence 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, and observe that the projector is not tilted hor-
izontally. [Depending on the image size (60 to 200 inches
diagonal: wide side), the projection distance is approx. 1.8
to 12 m by warranty.]
(2) Adjust the placement site and screen tilt so that the projec-
tion angle is perpendicular to the screen. Adjust the place-
ment site and screen position (height) so that the projection
lens center is at the lower edge of the screen.
(3) Project an image on the screen. (Connect video equipment
and power source, switch power on and select the input.)
(4) Fine adjust the projected image position and angle. If ad-
justing the placement site and screen cannot correct the
projected position (too low) or angle (lower part of image
widened), adjust front feet.
(5) By using "ZOOM" in LENS CONTROL, adjust for suitable
image size.
(6) By using "FOCUS" in LENS CONTROL, adjust to correct
image blur.
1.4.2 INSTALLATION SITE AND STATUS
The projector contains some fans for cooling. If the air inlets or
the vent holes of cooling fans are blocked, cooling efficiency may
deteriorate and temperature inside this unit will rise, and then it
can lead to 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.
Therefore, please make sure pay attention not to block the air in-
lets or the vent holes of cooling fans and allow sufficient space
around this unit.
REQUIRED SPACING:
Top = 15 cm / left and right sides = 30 cm / rear = 20 cm (When
this unit is enclosed in a space with dimensions as indicated
above, ventilate accordingly so that the internal and external
temperatures are the same.)
• Avoid locations that are wobbly or tilted. 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 tilt is greater than ±30°, 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 of the projector
over a long period of time.
• If mounted on a stand with casters, observe the casters are se-
curely broken 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. For dust protection, use adequate cau-
tion when providing external ventilation, filters.
Near water or in humid sites
Dust or grit
Oily or tobacco smokes
Near heaters or heat generating equipment
Direct sunlight
Very high or very low temperature
• To attach the unit to the ceiling mount bracket, set the torque
between the range of 1.5N m to 2.0N m.
