PRECAUTIONS

1.1 SAFETY 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.

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 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.

Insert 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

Connector

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
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.

(4) Leakage current test

Confirm specified or lower leakage current between earth
ground/power cord plug prongs and externally exposed
accessible parts (RF terminals, antenna terminals, video
and audio input and output terminals, microphone jacks,
earphone jacks, etc.).
Measuring Method : (Power ON)Insert load Z between
earth ground/power cord plug prongs and externally
exposed accessible parts. Use an AC voltmeter to
measure across both terminals of load Z. See Fig.1-1-9
and following Fig.1-1-12.

(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.
