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)

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 viscous (sticky, less prone to fl ow) 
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.

NOTES  ON  CHIP  COMPONENT  REPLACEMENT
•  Never reuse a disconnected chip component.
•  Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

COMPONENTS  IDENTIFIED  BY  MARK  0  OR  DOTTED  LINE  
WITH  MARK  0  ON  THE  SCHEMATIC  DIAGRAMS  AND  IN

NOTES  ON  THE  AC  POWER  ADAPTOR
•  When operating the unit with the internal batteries, remove the 

AC power adaptor from the wall outlet and the DC IN 9 V jack. 
Make sure that the plug of the external power source is discon-
nected before operating the unit.

•  Use the supplied Sony AC power adaptor only. The polarity 

of the plugs of other manufacturers may be different. Failure 
to use the supplied AC power adaptor may cause the unit to 
malfunction.

flashes in the display.
The next preset number from the most recent preset
is displayed (but if the last preset number was 20, 1 
will be displayed).

Turn TUNING/SELECT to select the preset
number, then press ENTER.

“PRESET COMPLETE!” appears in the display and
service or station is stored with the selected preset
number.

To preset another service or station, repeat these steps.

[

If you try to store another station with the same preset
number, the previously stored station will be replaced.

[

If DAB reception is poor, the service may not be stored.
