SECTION  1

SERVICING  NOTES

The SERVICING NOTES contains important information for servicing. Be sure to read this section before repairing the unit.

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)

 : LEAD  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 

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.

NOTE  OF  REPLACING  THE  FUSE

The fuse is or could be in the neutral. When a fuse is being replaced, 
the main plug shall be disconnected from the AC outlet to prevent 
electric shock.

ADVANCE  PREPARATION  WHEN  CONFIRMING  OPER-
ATION

All of the units included in the HT-S350 (SA-S350/SA-WS350/Re-
mote control) or HT-SD35 (SA-SD35/SA-WSD35/Remote control) 
are required to con

fi

 rming operation of this unit. Check in advance 

that you have all of the units.

DISCHARGE  PROCESSING

Before checking the operation of the boards for the electric shock 
prevention, perform the discharge processing by connecting the re-
sistor at both ends of the speci

fi

 ed capacitor with referring to the 

fi

 gure below.

Note:

 Be sure to discharge using a resistor of 800 

 or higher.

(for C3)

ABOUT  THE  PROTECTION

If the status indicator on the subwoofer 

fl

 ashes in red, press the [

1

button of the subwoofer to turn the power o

ff

  and check whether the 

ventilation holes of the subwoofer is not blocked, leave it for a while 
and turn the power on again.

NOTE  OF  PERFORMING  THE  OPERATION  CHECK  IN  
THE  STATE  THAT  HEAT  SINK  IS  REMOVED

When performing the operation check in the state that this unit is 
disassembled, it is possible to perform the operation check in the 
state that heat sink is removed from the MAIN board.
However, in that case, volume setting to low and work in a short 
time of about several minutes.
If you need more than volume setting to medium, or more than a 
few minutes of work, be sure to work with attach the heat sink to 
the MAIN board.
