-Safety Precautions

1. This design of this product contains special hardware and many circuits and components specially for safety
purposes. For continued protection, no changes should be made to the original design unless authorized in
writing by the manufacturer. Replacement parts must be identical to those used in the original circuits. Services
should be performed by qualified personnel only.

2. Alterations of the design or circuitry of the product should not be made. Any design alterations of the product
should not be made. Any design alterations or additions will void the manufacturers warranty and will further
relieve the manufacture of responsibility for personal injury or property damage resulting therefrom.

3. Many electrical and mechanical parts in the products have special safety»related characteristics. These
characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily
be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which
have these special safety characteristics are identified in the Parts List of Service Manual. Electrical
components having such features are identified by shading on the schematics and by (/i\) on the Parts List in
the Service Manual. The use of a substitute replacement which does not have the same safety characteristics
as the recommended replacement parts shown in the Parts List of Service Manual may create shock, fire, or
other hazards.

4. The leads in the products are routed and dressed with ties, clamps, tubings, barriers and the like to be
separated from live parts, high temperature parts, moving parts and/or sharp edges for the prevention of
electric shock and fire hazard. When service is required, the original lead routing and dress should be
observed, and it should be confirmed that they have been returned to normal, after re-assembling.

5. Leakage currnet check (Electrical shock hazard testing)

After reassembling the product, always perform an isolation check on the exposed metal parts of the product

(antenna terminals, knobs, metal cabinet, screw heads, headphone jack, control shafts, etc.) to be sure the

product is safe to operate without danger of electrical shock.

Do not use a line isolation transformer during this check.

0 Plug the AC line cord directly into the AC outlet. Using a "Leakage Current Tester", measure the leakage
current from each exposed metal parts of the cabinet, particularly any exposed metal part having a return
path to the chassis, to a known good earth ground. Any leakage current must not exceed 0.5mA AC (r.m.s.).

0 Alternate check method
Plug the AC line cord directly into the AC outlet. Use an AC voltmeter having, 1,000 ohms per volt or more
sensitivity in the following manner. Connect a 1,500 Q10W resistor paralleled by a 0.15M F AC-type capacitor

between an exposed metal part and a known good earth ground. AC VOLTMETER
Measure the AC voltage across the resistor with the AC a (Having1000

-Warning A CAUTION

1.This equipment has been designed and manufactured to meet international safety standards.
2. It is the legal responsibility of the repairer to ensure that these safety standards are maintained.
3. Repairs must be made in accordance with the relevant safety standards.

4. It is essential that safety critical components are replaced by approved parts.

5. If mains voltage selector is provided, check setting for local voltage.

Burrs formed during molding may
be left over on some parts of the
chassis. Therefore, pay attention to
such burrs in the case of
preforming repair of this system.

In regard with component parts appearing on the silk-screen printed side (parts side) of the PWB diagrams, the
parts that are printed over with black such as the resistor (-), diode (h) and ICP (Q) or identified by the "A"
mark nearby are critical for safety.

When replacing them, be sure to use the parts of the same type and rating as specified by the manufacturer.

I COM PU LINK Remote Control System

gs l

The COM PU LINK remote control system allows you to operate 1 VC audio components through the remote sensor on

the receiver.

To use this remote control system, you need to connect JVC audio

components through the COMPU LINK (SYNCHRO) jacks (see

below) in addition to the connections using cables with RCA pin

plugs (see pages 5 and 6).

0 Make sure that the AC power cords of these components are
unplugged before connection. Plug the AC power cords only after
all connections are complete.

Notes:

- There are four versions of COMPU LINK remote control system.
This receiver is equipped with the fourth version - COMPU LINK-
4. This version is added systematic operations with the CD recorder
to the previous version - COMPU LINK-3.

- If your audio component has two COMPU LINK jacks, you can use
either one. If it has only one COMPU LINK jack, connect it so that it
is the last item in the series of components. (For example, the
turntable or CD player in the diagram above.)

- To operate the cassette deck or MD recorder using the COMPU
LINK remote control system, set the source name correctly. (See
page 16.)

- Refer also to the manuals supplied with your audio components.

This remote control system allows you to use four functions listed
below.

Remote Control through the Remote Sensor on the
Receiver

You can control the connected audio components through the remote
sensor on the receiver using this remote control. Aim the remote
control directly at the remote sensor on the receiver. For details, see
pages 51 and 52.

When you press the play (>) button on a connected component or
on its own remote control, the receiver automatically turns on and
changes the source to the component. On the other hand, if you
select a new source on the receiver or on the remote control, the
selected component begins playing immediately.

In both cases, the previously selected source continues playing
without sound for a few seconds.

Automatic Power On/ Off (Standby): only possible
with the COMPU LINK-3 and COMPU LINK-4
connection

The connected components turn on and off (standby) along with the
receiver.

When you turn on the receiver, one of the connected components
will turn on automatically, depending on which component has been
previously selected.

When you turn off the receiver, the connected components will turn
off (standby).

Synchronized Recording

Synchronized recording means the ca sette deck (or MD recorder)
starts recording as soon as a CD begins playing.

To use synchronized recording, follow these steps:

1. Put a tape in the cassette deck (or an MD in the
MD recorder), and a disc in the CD player.

2. Press the record (0) button and the pause (II)
button on the cassette deck (or MD recorder) at
the same time.

This puts the cassette deck (or MD recorder) into recording
pause.

If you do not press the record (0) button and pause (II) button at
the same time, the synchronized recording feature will not
operate.

3. Press the play (b) button on the CD player.
The source changes on the receiver, and a' soon as play starts,
the cassette deck (or MD recorder) starts recording. When the
play ends, the ette deck (or MD recorder) enters recording
pause, and stops about 4 seconds later.

Notes:

- During synchronized recording, the selected source cannot be
changed.

- If the power of any component is shut off during synchronized
recording, the COMPU LINK remote control system may not
operate properly. In this case, you must start again from the
beginning.
