•

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.

The laser diode in the optical pick-up 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.

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 pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

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)

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.

To use the remote
Slide and remove the battery compartment lid 

wk

, and 

insert the two supplied R6 (size AA) batteries, E side 
first, matching the polarities shown below. 

• With normal use, the batteries should last for about six months.

• Do not mix an old battery with a new one or mix dierent types of 

batteries.

• If you do not use the remote for a long period of time, remove the 

batteries to avoid damage from battery leakage and corrosion.

Turn on the system.

To run the DAB Automatic Scan
When you turn on the system for the first time after 
you purchase the system, DAB Automatic Scan starts 
automatically and creates a list of available services.
If you want to run the DAB Automatic Scan again, 
perform the procedure below.

Press DAB AUTO SCAN

“DAB Auto Scan? Push ENTER” appears.

Press PUSH ENTER on the unit (or ENTER on the 
remote) qd.

scanning may take a few minutes.

When scanning is complete, a list of available services 
is created.

• If your country or region does not support DAB broadcast, “No 

Service” appears.

• Do not press any button on the unit or the remote during DAB 

Automatic Scan. Scanning is interrupted and service list may not be 
created properly. In this case, run the DAB Automatic Scan again.

• If you move to another area, repeat this procedure to store the 

stations for your new area.

• This procedure clears all previously stored presets.

• Before unplugging the DAB antenna, make sure the system is turned 

off to preserve your own DAB settings.

• This tuner does not support data services.

operation as SHUF Play.

• When you turn on the system, the disc is not pulled into the disc slot 

until “No Disc” appears in the display. Do not attempt to push in the 
disc until “No Disc” appears.

• If you load a disc that is not playable by this system, it will be ejected 

automatically.

• Do not load an 8 cm disc with an adaptor. Doing so may cause the 

system to malfunction.

• When you remove a disc, handle the disc by its edge and pull it 

straight out of the disc slot. Do not touch the surface.

Only the first 9 characters are displayed when performing the group 
search, track search, or file search.

• All tracks or les on a disc are played repeatedly up to five times. 

• “REP 1” indicates that a single track or file is repeated until you stop 

it.

• Do not save other types of les or unnecessary groups on a disc that 

has MP3 fies.

• Groups that have no MP3 les are skipped.

• MP3 les are played back in the order that they are recorded onto 

the disc.

• The system can only play MP3 les that have a le extension of 

“.MP3.”

• If there are les on the disc that have the “.MP3” file extension, 

but that are not MP3 les, the unit may produce noise or may 
malfunction.

• The maximum number of:

– groups is 256 (including the root folder).
– MP3 les is 511.
– MP3 les and groups that can be contained on a single disc is 512.
– directory levels (the tree structure of les) is 8.

• Compatibility with all MP3 encoding/writing soware, recording 

device, and recording media cannot be guaranteed. Incompatible 
MP3 discs may produce noise or interrupted audio or may not play 
at all.

• If the disc begins with a CD-DA (or MP3) session, it is recognized as 

a CD-DA (or MP3) disc, and other sessions are not played back.

• A disc with a mixed CD format is recognized as a CD-DA (audio) 

disc.
