Important 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.
@ Precautions during Servicing
Locations requiring special caution are denoted by labels and 10. Products using cathode ray tubes (CRTs)
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 opera-
tion and service manuals.
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.
Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
. Use specified insulating materials for hazardous live parts. Note
especially:
1) Insulation Tape
2) PVC tubing
3) Spacers
4) Insulation sheets for transistors
. When replacing AC primary side components (transformers,
power cords, noise blocking capacitors, etc.) wrap ends of wires
securely about the terminals before soldering.
‘ire Bo 47
Fig. 1
. Observe that wires do not contact heat producing parts (heat-
sinks, oxide metal film resistors, fusible resistors, etc.)
. Check that replaced wires do not contact sharp edged or pointed
parts.
. When a power cord has been replaced, check that 10—15 kg of
force in any direction will not loosen it.
Power cord
Fig. 2
9. Also check areas surrounding repaired locations.
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.
Consequently, when servicing these products, replace the cath-
ode ray tubes and other parts with oniy 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.
. Crimp type wire connector
In such cases as when replacing the power transformer in sets
where the connections between the power cord and power
transformer 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.
1) Connector part number : E03830-001
2) Required tool : Connector crimping tool of the proper type
which wil! not damage insulated parts.
3) Replacement procedure
(1) Remove the old connector by cutting the wires at a point
close to the connector.
Important : Do not reuse a connector (discard it).

(2) 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.

FEATURES
@ Can be extended up to 100 m (325 ft)
The distance between the camera and remote control unit
can be extended up to 100 m (325 ft) using the optional
VC-P110 series camera cables. Even in this case the camera
power is supplied from the RM-P200; therefore, it is not
necessary to prepare a separate power supply for the
camera.
©@ Built-in genlock function
Genlock operation is possible with a composite video signal
(VBS) or black burst (B.B.) signal. In addition, SC phase
and H phase can be adjusted on the front panei.
@ Camera control by serial data communication
A serial data transmission method is employed for camera
control signals.
The camera and remote contro! unit are connected with
two data lines; CPUs built in the camera and the remote
control unit perform mutual communications when con-
trolling the camera so that accurate and reliable control
becomes possible.
@ Multiple outputs
The unit is equipped with two output connectors for the
composite video signal. Moreover, any of the following can
be selectively output according to purpose and use: R/G/B
component signals, Y/R-Y/B-Y component signals or separate
Y/C signals compatible with S-VHS VTRs.
PRECAUTIONS
Safety Precautions
@ Use only with the rated power supply.
@ Do not modify the unit or operate it with the cover panel
removed.
@ Do not allow inflammable objects, water or metallic objects
to get inside the unit as it will cause damage or malfunction.
