for personal injury or property damage resulting therefrom. .
.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 (A\) on the Parts
List in the Service Manual. The use of a substitute repalcement: 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.
. The leads in the products are routed and dressed with ties, clanips; 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.
. Leakage currnet check (Electrical shock hazard testing)
After re-assembling the product, always perform an isolation check on the exposed metal
parts of the product (antenna terminals, knobs, metal cabinet, screw heads, headphone jack,
contorl 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.
e 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.).
e 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 1,500Q 10 W
resistor paralleled by a 0.15 «F AC-type capacitor between an exposed metal part and a
known good earth ground.
Measure the AC voltage across the resistor
with the AC voltmeter.
Move the resistor connection to each exposed
metal part, particularly any exposed metal part
having a return path to the chassis, and
meausre the AC voltage across the resistor.

Connections remote.control system. This system connects other JVC audio components with the receiver
to make listening andrecording more convenient. Touse this system, attach the cables provided
with your JVC components to the COMPU LINK-3 SYNCHRO jacks on the rear panel of each
component. Then connect the cables to the receiver.
NOTES:
¢ COMPU LINK-3 is an upgraded version of COMPU LINK-1. If your equipment
provides COMPU LINK-I jacks, you can still connect your equipment, but slight
imperfections may result. Automatic Power ON/OFF, for example, may not always
function properly.

When the power supply is connected correctly, the POWER STANDBY indicator lights on the
front of the receiver. A small amount of power (5 watts) is consumed under these conditions,
evenif the receiver is turned off. To shut off the power completely, unplug the power cord from
the outlet. .
Z\ CAUTION!
Do not handle the power cord with wet hands.
Do not pull on the power cord to unplug the receiver. Always grasp the plug
directly so as not fo damage the cord.
Do not plug the power cord into a socket until all components are connected
correctly.
IMPORTANT! If the power cord is disconnected or a power failure occurs, the

Presetting Tuned Frequencies
You can preset up to 40 radio stations by assigning channel numbers (1 through 40) to them.
Once a station is preset, you can listen to it by entering the preset number using the TUNER
buttons on the receiver, or the PRESET buttons of the remote. There are two ways to preset:
manual or automatic.
To choose numbers from 1 through 10, press the appropriate TUNER buttons. To choose
numbers from 11 through 40, press the +10 key and one other button. For example:
To choose 17 Press +10, then 7.
To choose 20 Press +10, then 10.
To choose 25 Press +10 twice, then 5.
To choose 40 —_—-Press +10 three times, then 10.
Your channel number will appear as shown atthe left.
NOTE: You can also tune using the remote control. First press the AM or FM button
on the remote, then enter the channel number using the PRESET buttons (+ and -)
on the remote., Press + to raise the selected number, and press - to lower the
selected number.
To use manual presetting to assign channel numbers to your favorite stations, follow these
steps:
Step1 Tune toa station. If necessary, follow the procedure on page 14.
Step 2 Press the MEMORY button.
The “MEMORY” light appears in the display window.
Step 3 Using the TUNER buttons, enter anumber (1 through 40). This number is the channel
number you are. assigning to the station.
IMPORTANT! You musi enter the channel number while the “MEMORY” light is on.
You have about 5 seconds to do this. If the light disappears before you enter the

COMPU LINK Remote Control'System -:
The COMPU LINK remote control system lets you operate the récéiver and JVC components
«from the remote supplied with this receiver. Control signals for JVC audio components are
preset in the receiver’s remote control.
Connecting the COMPU LINK SYNCHRO-3 jacks on the back of the receiver will allow you
to use the four functions below.
~ Youcan-control all components via the REMOTE SENSOR on the receiver using the receiver’s
remote e control: For details; see page 19. ‘
IMPORTANT! Point the remote control directly at the REMOTE SENSOR on the
* receiver.
When you press play on a component or the remote, the component begins playing immedi-
ately. On the other hand, if you select anew source onthe receiver or the remote, the component
begins playing immediately, but the e Brevionsly selected source continues playing without
sound for a few seconds.
Synchronized recording means the tape deck starts recording as soon as a CD or record begins
playing.
To use synchronized recording, follow these steps:
Step 1 Puta tape in the deck, and a disc in the CD player or on the turntable.
Step 2 Press the REC and PAUSE button on the tape deck at the same time. This puts the
tape deck in the REC/PAUSE state.
IMPORTANT! If you do not press the REC button and PAUSE button together, the
synchronized recording feature will not operate.
Step 3 Press the PLAY button on the CD player or turntable.
As soon as the disc starts playing, the tape deck starts recording. When the disc ends, the tape
deck switches back to the REC/PAUSE mode, and stops 4 seconds later.
NOTES:
¢ During synchronized recording, the CD or PHONO button is activated. Other
SOURCE buttons are disabled to prevent recording failure.
* Ifyour CD player is operated in the PROGRAM mode, a 4-second mute is recorded
between tracks to enable the music scan feature of your tape deck to work.
¢ If the power of any component is shut off during synchronized recording, the system
will not operate properly. In this case, you must start again with step 1.
The CD player and cassette deck are turned on and off along with the receiver.
NOTE: This function has been added to COMPU LINK-3 (Enhanced COMPU LINK),
an upgraded version of COMPU LINK-1. Refer to your JVC component manual for
details.
