Notes on chip component replacement
Never reuse a disconnected chip component.
Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
Keep  the temperature of the soldering iron around 270 ˚C
during repairing.
Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
Be careful not to apply force on the conductor when soldering
or unsoldering.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.
SAFETY  CHECK-OUT
After correcting the original service problem, perform the following
safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, screws,
and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE  TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication
is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
of a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V AC range are suitable.  (See
Fig. A)

Notes about CD-R/CD-RW/DVD-R/
DVD-RW/DVD+R/DVD+RW
In some cases, CD-R/CD-RW/DVD-R/DVD-RW/
DVD+R/DVD+RW cannot be played on this system 
due to the recording quality or physical condition of the 
disc, or the characteristics of the recording device and 
authoring software.
The disc will not play if it has not been correctly 
finalized. For more information, see the operating 
instructions for the recording device.
Note that discs created in the Packet Write format 
cannot be played.
Music discs encoded with 
copyright protection 
technologies
This product is designed to play back discs that 
conform to the Compact Disc (CD) standard.
Recently, various music discs encoded with copyright 
protection technologies are marketed by some record 
companies. Please be aware that among those discs, 
there are some that do not conform to the CD standard 
and may not be playable by this product.
Note on DualDisc
A DualDisc is a two sided disc product which mates 
DVD recorded material on one side with digital audio 
material on the other side. However, since the audio 
material side does not conform to the Compact Disc 
(CD) standard, playback on this product is not 
guaranteed.
Note about DVD-RW (Except for 
U.S./Canadian/European models)

Note on PBC (Playback 
Control) (VIDEO CDs)
This system conforms to Ver. 1.1 and Ver. 2.0 of 
VIDEO CD standards. You can enjoy two kinds 
of playback depending on the disc type.
Disc type
You can
VIDEO CDs 
without PBC 
functions 
(Ver. 1.1 discs)
Enjoy video playback (moving 
pictures) as well as music.
VIDEO CDs 
with PBC 
functions 
(Ver. 2.0 discs)
Play interactive software using 
menu screens displayed on the 
TV screen (PBC Playback), in 
addition to the video playback 
functions of Ver. 1.1 discs. 
Moreover, you can play high-
resolution still pictures, if they 
are included on the disc.
About Multi Session CD
• This system can play Multi Session CDs when 
an MP3 audio track is contained in the first 
session. Any subsequent MP3 audio tracks 
recorded in later sessions can also be played 
back.
• This system can play Multi Session CDs when 
a JPEG image file is contained in the first 
session. Any subsequent JPEG image files 
recorded in later sessions can also be played 
back. 
• If audio tracks and images in music CD format 
or video CD format are recorded in the first 
session, only the first session will be played 
back.
About the Super Audio CD
Super Audio CD is a new high-quality audio 
disc standard where music is recorded in the 
DSD (Direct Stream Digital) format 
(conventional CDs are recorded in the PCM 
format). The DSD format, using a sampling 
frequency 64 times higher than that of a 
conventional CD, and with 1-bit quantization, 
achieves both a wide frequency range and a wide 
dynamic range across the audible frequency 
range, and so provides music reproduction 
extremely faithful to the original sound.
Types of Super Audio CDs
There are two types of discs, depending on the 
Super Audio CD layer and CD layer 
combination.
Super Audio CD layer: A high-density 
signal layer for Super Audio CD
CD layer*
1
: A layer that is readable by a 
conventional CD player
*1 You can play the CD layer on a conventional CD 
player.
*2 Since both layers are on one side, it is not necessary 
to turn the disc over.
*3 To select a layer, see “Selecting a Playback layer for 
a Super Audio CD”.
Region code
Your system has a region code printed on the 
back of the unit and will only play DVDs labeled 
with the same region code.
DVD VIDEOs labeled 
 will also play on this 
system.
If you try to play any other DVD VIDEO, the 
message [Playback prohibited by area 
limitations.] will appear on the TV screen. 
Depending on the DVD VIDEO, no region code 
indication may be given even though playing the 
DVD VIDEO is prohibited by area restrictions.
Note on playback operations 
of DVDs and VIDEO CDs
Some playback operations of DVDs and VIDEO 
CDs may be intentionally set by software 
producers. Since this system plays DVDs and 
VIDEO CDs according to the disc contents the 
software producers designed, some playback 
features may not be available. Also, refer to the 
instructions supplied with the DVDs or VIDEO 
CDs.
