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.

Refer to SUPPLEMENT-1 for printed wiring board, schematic di-
agram and electrical parts list of ICF-F12S: Saudi Arabia model. 
When repairing the set of ICF-F11S and ICF-12S: E model, refer 
to either of original service manual/SUPPLEMENT-1 according 
to the set.

COMPONENTS  IDENTIFIED  BY  MARK 0 OR  DOTTED  LINE  
WITH  MARK 0 ON  THE  SCHEMATIC  DIAGRAMS  AND  IN  
THE  PARTS  LIST  ARE  CRITICAL  TO  SAFE  OPERATION.
REPLACE  THESE  COMPONENTS  WITH  SONY  PARTS 

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 viscou-s (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.

HOW  TO  CHANGED  THE  CERAMIC  FILTERS
This model is used two ceramic fi lters of CF1 and CF3.
You must used same type of color marked ceramic fi lters in order 
to meet same specifi cations.
Therefore, the ceramic fi lter must be changed two pieces together 
since it’s supply two pieces in one package as a spare parts.

Standards. The actual battery life may vary
depending on the circumstance of the unit.

When to replace the batteries
When the sound  becomes weak or distorted, replace
all the batteries with new ones.

Notes on batteries
• Do not charge the dry batteries.
• Do not carry the dry batteries with coins or other

metallic objects. It can generate heat if the positive
and negative terminals of the batteries are
accidentally contacted by a metallic object.

• Do not use different types of batteries at the same

time.

• When you replace the batteries, replace all with new

ones.

• When you are not going to use the unit for a long

time, remove the batteries to avoid damage from
battery leakage and corrosion.

B)

FM: Extend the telescopic antenna and adjust the

angle for optimum reception.

MW: Rotate the unit horizontally for optimum

reception. A ferrite bar antenna is built into the
unit.

SW: Extend the telescopic antenna vertically.

Note
Adjust the direction of the
antenna by holding the bottom of
it. The antenna can be damaged
when you move the antenna with
excessive force.
