• 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.

• All CD-Rs other than music and VCD format 

CD-Rs

• Data part of CD-Extras
• DVD-ROMs
• DVD Audio discs

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.

Your system has a region code printed on the 
back of the unit and will only play DVDs labeled 
with identical region code.
DVDs labeled 

 will also be played on this 

system.
If you try to play any other DVD, the message 
“Playback prohibited by area limitations.” will 
appear on the TV screen.

Depending on the DVD, no region code 
indication may be labeled even though playing 
the DVD is prohibited by area restrictions.
The region code is located below the 
COMPONENT VIDEO OUT jacks on the rear 
panel.

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.

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.
