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.
Fig.1-1-6
e) Check the four points noted in Fig.1-1-7.

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.

1.6 INSTALLATIONS
1.6.1 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.
*Refer to the WEB instruction manual for the projection dis-
tance.
Example: For 16:9 and the screen size is 60 inch, the tele-
end will be 1.75m; for 280 inch, the wide end will be
17.14m.
(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) Slight adjustment will be made to the projection position
and projection angle of the image. When the projection po-
sition (height) shifts downward or when the projection an-
gle is not appropriate (lower end of the image widens) and
adjustment cannot be made to the installation location and
screen, adjust using the 4 movable feet at the bottom.
(5) By using "ZOOM" in LENS CONTROL, adjust for suitable
image size.
(6) By using "FOCUS" in LENS CONTROL, adjust to correct
image blur.
1.6.2 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.
1.6.3 DO NOT INSTALL AT THE FOLLOWING.
This unit is a precision device. Please refrain from installing or
using it at the following locations. Otherwise, it may cause fire or
malfunction.
• Dusty, wet and humid places
• Places subject to oily smoke or cigarette smoke
• On top of a carpet or bedding, or other soft surfaces
• Places exposed to direct sunlight
• Places with a high or low temperature
• Do not install this unit in a room that is oily or subject to ciga-
rette smoke. Even a small quantity of smoke or oiliness can
have a long-term impact on this unit.
* This unit produces a great amount of heat, and is designed to
take in cool air to cool its optical components. Using the unit at
the above locations may cause dirt to attach to the light path,
thereby resulting in dark images or dull colors.
* Dirt that sticks to the optical components cannot be removed.
1.6.4 MAINTAIN CLEARANCE FROM THE WALL, ETC.
As the unit discharges a large amount of heat, install it with ade-
quate clearance from the surroundings as shown below.
Leave the front area of the unit unblocked.
If there is any obstructing object in front of the exhaust vent, hot
air will flow back to the unit and cause it to heat up. Hot air flowing
out of the unit may cause shadows on the screen (heat haze phe-
nomenon).

448 to 462 and OD value 5 or above.
• Your eyes will not be protected if the wavelength range of the
goggles is not within the specified range.
• The higher the OD value, the greater the protection level the
laser safety goggles provide. The attenuation of incident light
increases thereby lowering the transmittance.
• Do not look into the light even when using the laser safety gog-
gles. (Light leakage equivalent to Class 4 may emit from the
projection lens and gap between the cover.)
• Do not expose the laser safety goggles to direct laser beam.
Otherwise, it may damage the goggles.
• Do not use laser other than the laser and wavelength specified.
(There may be lasers of the same name with different wave-
lengths)
• Do not remove the laser safety goggles during operations.
• Do not use the laser safety goggles as light shielding goggles
for welding.
• The complete absorption-type products are not protective
equipment that absorbs laser beam completely. (Check the
absorption characteristics of the safety goggles.)
• Do not use products with a standard visible light transmittance
of 20% or less in dark areas.
• Do not use the laser safety goggles once the goggles have
been exposed to high laser energy or if the goggles are dam-
aged.
• The laser safety goggles absorb a great amount of light of spe-
cific wavelengths. This affects the color balance of your eyes
temporarily after a long period of use.
• Usage environment, storage environment (direct sunlight, high
temperature, or high humidity), and scratches may change the
optical density of the goggles. Replace the goggles periodical-
ly.
2.3.2 What is the OD (Optical Density) value?
• The amount of transmitted light is expressed as transmittance %.
• The greater the absorption (transmittance % very close to ze-
ro) of specific wavelengths such as laser light, the safer it is for
your eyes.
• When the transmittance becomes lower, the number of zeros
increases in the decimal fraction making it complicated and
difficult to interpret the value.
• Optical Density (OD) value expresses transmittance in an easy
to understand manner.
• Optical Density is the logarithm of the degree of absorption.
The relationship with transmittance is shown in the following
table.
