• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be

damaged by heat.

• 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.

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.

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.

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)

Your player has a region code printed on the 
back of the unit and will onl y play DVD 
VIDEOs (playback only) labeled with 
identical region codes. This system is used to 
protect copyrights.

DVD VIDEOs labeled 

 will also play on 

this player.

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 labeled even though 
playing the DVD VIDEO is prohibited by 
area restrictions.

The player cannot play the following discs:
• CD-ROMs/CD-Rs/CD-RWs other than 

those recorded in the format listed on the 
previous page.

• Data part of CD-Extras
• DVD-ROMs
• DVD Audios

Also, the player cannot play the following 
discs:
• A DVD VIDEO with a different region 

code.

• A  disc  recorded in a color system other than 

NTSC, such as PAL or SECAM (this player 
conforms to the NTSC color system).

• A  disc that has a non-standard shape (e.g., 

card, heart).

• A  disc  with  paper or stickers on it.
• A  disc that has the adhesive of cellophane 

tape or a sticker still left on it.

• DVD-Rs recorded in VR mode (Video 

Recording format)

• Copy-Once programs recorded on CPRM* 

compatible DVD-Rs. 

* CPRM; Content Protection for Recordable Media 

is a coding technology that protects copyright for 
Copy-Once programs.

• Notes about DVD+RWs/DVD+Rs, DVD-RWs/

DVD-Rs or CD-Rs/CD-RWs
Some DVD+RWs/DVD+Rs, DVD-RWs/DVD-
Rs or CD-Rs/CD-RWs cannot be played on this 
player 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 
some playback functions may not work with some 
DVD+RWs/DVD+Rs, even if they have been 
correctly finalized. In this case, view the disc by 
normal playback. Also some DATA CDs created 
in Packet Write format cannot be played.

technologies
This product is designed to playback 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. 

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.

Some playback operations of DVDs and 
VIDEO CDs may be intentionally set by 
software producers. Since this player 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.

This product incorporates copyright
