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.
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.

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.
Format of 
discs
Disc logo
• 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.
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.
DVDs labeled 
 will also play 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 given 
even though playing the DVD is prohibited by 
area restrictions.
Examples of discs that the 
system cannot play
The system cannot play the following discs:
• CD-ROMs (except for extension “.MP3,” 
“.JPG,” or “.JPEG”)
• CD-Rs/CD-RWs other than those recorded in 
the following formats:
− audio CD format
− video CD format
− MP3/JPEG format that conforms to 
ISO9660* Level 1/Level 2, or its extended 
format, Joliet
• Data part of CD-Extras

 
DVD Audio discs
DVD-RAMs
Progressive JPEG file
A logical format of files and folders on CD-ROMs, 
defined by ISO (International Organization for 
standardization)
Do not load the following discs: 
 
A DVD with a different region code.
 
A disc that is neither standard nor circular 
(e.g., card, heart, or star shape).

A disc that has adhesive or cellophane tape still 
left on it.
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 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 discs created in the Packet Write 
format cannot be played.
M usic  d iscs  en co ded  w it h 
c opyrigh t   p rot ec t ion 
t e ch nol og ies
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.
Note on DualDiscs
This product is designed to playback discs that 
conform to the Compact Disc (CD) standard. A 
DualDisc is a two sided disc product which 
mates DVD recorded material on one side with 
digital audio material on the other side. Please 
be aware that the audio side of a DualDisc may 
not play on this product because these discs do 
not conform to the CD standard.
“DualDisc” is a trademark of the Recording 
Industry Association of America (RIAA).
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 
ALL
software producers designed, some playback 
features may not be available. Also, refer to the 
instructions supplied with the DVDs or VIDEO 
CDs.

HCD-LF10
The laser diode in the optical traverse unit block may suffer
electrostatic break-down because of the potential difference
generated by the charged electrostatic load, etc. on clothing and the
human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical traverse
unit. Therefore, when checking the laser diode emission, observe
from more than 30 cm away from the objective lens.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
Unleaded solder melts at a temperature about 40 
°
C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 
°
C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

Memory Check”. (See page 30)
4. Press the [CLEAR] key on the remote commander, and initialize
memory.
NOTE  OF  REPLACING  THE  DMB07  BOARD-2
New part of EEPROM (IC204, IC903) on the DMB07 board cannot
be used. Therefore, if the mounted DMB07 board is replaced,
exchange new EEPROM with that used before the replacement.
