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.

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