• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

• Keep the temperature of the soldering iron around 270 ˚C dur-

ing 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 ra-
diation exposure.

The following caution label is located inside the apparatus.

This appliance is classified as
a CLASS 1 LASER product.
The CLASS 1 LASER
PRODUCT MARKING is
located on the rear exterior.

After correcting the original service problem, perform the follow-
ing 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.

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” indica-
tion is 0.75 V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-
amples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2 V AC range are suit-
able.  (See Fig. A)

Some CD-Rs/CD-RWs or DVD-Rs/DVD-RWs
cannot be played on this system depending upon the
format or the recording quality or physical condition
of the disc, or the characteristics of the recording
device.
Furthermore, the disc will not play if it has not been
correctly finalized. For more information, see the
operating instructions for the recording device.

MP3 (MPEG 1 Audio Layer-3) is a standard
technology and format for compressing a sound
sequence. The track is compressed to about
1/10 of its original size. Sounds outside the
range of human hearing are compressed while
the sounds we can hear are not compressed.

You  can play MP3 audio tracks recorded on CD-
ROMs, CD-Rs (recordable CDs), or CD-RWs
(rewritable CDs).
The disc must be in the ISO 9660* level 1, level 2 or
Joliet format.

The most common international standard for the
logical format of tracks and albums on a CD-ROM.
There are several specification levels. In Level 1,
track names must be in the 8.3 format (no more than
eight characters in the name, no more than three
characters in the extension “.MP3”) and in capital
letters. Album names can be no longer than eight
characters. There can be no more than eight nested
album levels. Level 2 specifications allow album
names and track names up to 31 characters long.

• With formats other than ISO 9660 level 1, 2 and

Joliet, album names or track names may not be
displayed correctly.

• When naming, be sure to add the extension “.MP3”

to the track name.

• If you use the extension “.MP3” to a track other

than MP3, the player cannot recognize the track
properly and will generate random noise that could
damage your speakers.

• A disc recorded with complicated tree structure

takes a longer time to start playback.

• When the disc is inserted, the player reads all the

tracks on that disc. If there are many albums or non-
MP3 files on the disc, it may take a long time for
player to begin or for the next MP3 audio tracks to
start play.

• We recommend that you do not save other types of

tracks or unnecessary albums than MP3 audio
tracks in the disc to be used for MP3 listening.

• An album that does not include an MP3 audio track

is skipped.

• Maximum album number in a disc: 99

(The maximum number of MP3 audio tracks that
can be contained on a album is 250.)

• Tracks and albums are played in the order they are

recorded on the disc.

• Only the letters in the alphabet and numbers can be

used for album or track names. Anything else is
displayed as a space.

• ID3 tags cannot be displayed in stop mode.
• The player cannot play audio tracks in MP3PRO

format.
