•

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

•

Be careful not to apply force on the conductor when soldering

or unsoldering.

Design and specifications are subject to change without notice.

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

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.

The disc table lock function for the antitheft of an demonstration
disc in the store is equipped.

1. Press the  

I

/1

  button to turn the power on.

2. While pressing the

x

button, press the

Z

button until

“UNLOCKED”  displayed on the fluorescent indicator tube
(around 5 seconds).

When “LOCKED” is displayed, the antitheft lock is not released by
turning power on/off with the

I/

1

button.

Slide and remove the battery compartment lid ̱, and 
insert the two supplied R6 (size AA) batteries, × side 
first, matching the polarities shown below. 

Notes on using the remote
• With  normal use, the batteries should last for about six months.
• Do  not mix an old battery with a new one or mix different 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.
Press ÒÄÆ (power) ȩ.

Select the clock set mode.

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 ̨ on the unit.
“AUTO SCAN” and “PUSH ENTR” appear.

Press PUSH ENTER on the unit (or ENTER on the 
remote) ̠.
Scanning begins. The scanning progress is indicated 
by advancing asterisks. Depending on the DAB 
services available in your area, scanning may take a 
few minutes.

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

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

SERV” 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.

Notes on playing MP3 discs
• Do not save other types of files or unnecessary folders on a disc that 

has MP3 files.

• Folders that have no MP3 files are skipped.
• MP3 files are played back in the order that they are recorded onto 

the disc.

• The system can only play MP3 files that have a file extension of 

“.MP3.”

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

but that are not MP3 files, the unit may produce noise or may 

malfunction.

• The maximum number of:

– folders is 255 (including the root folder).
– MP3 files is 511.
– MP3 files and folders that can be contained on a single disc is 512.
– folder levels (the tree structure of files) is 8.

• Compatibility with all MP3 encoding/writing software, recording 

device, and recording media cannot be guaranteed. Incompatible 

MP3 discs may produce noise or interrupted audio or may not play 

at all.

Notes on playing multisession discs
• 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.
