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.)

EAD 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 viscous (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.

SAFETY-RELATED COMPONENT WARNINGII

COMPONENTS IDENTIFIED BV MARKA OR DO'I'I'ED LINEWITH
MARK A ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS
LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE
COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS
APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS
PUBLISHED BY SONY.

CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.

Flexible Circuit Board Repairing

0 Keep the temperature of the soldering iron around 270 aC dur-
ing repairing.

- Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).

0 Be careful not to apply force on the conductor when soldering
or unsoldering.

Notes on chip component replacement

0 Never reuse a disconnected chip component.

0 Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

Notes on the power source
Disconnect all power sources when the CD player is not used for a long time.

On Ac power adaptor

- Use only the AC power adaptor supplied.
If your CD player is not supplied with the one, use the AC-E45HG AC
power adaptor. Do not use any other AC power adaptor. It may cause a
malfunction.

Polarity at the plug
9-6
M

- Do not touch the AC power adaptor with wet hands.

' Connect the AC power adaptor to an easily accessible AC outlet. Should
you notice an abnormality in the AC power adaptor, disconnect it from
the AC outlet immediately.
