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.

ADVANCE  PREPARATION  WHEN  CONFIRMING  OP-
ERATION
Main unit (HBD-L600 or HBD-L800 or HBD-L800M), front 
speakers (SS-TSL600 or SS-TSL800) and wireless transceiver 
(EZW-RT20 or EZW-RT50) are required to confi rming operation 
of the subwoofer (SA-WSL600). Check in advance that you have 
all of the units.

NOTE  WHEN  VOLTAGE  IS  MEASURED
Confi rm fan motor is connected without fail when you confi rm the 
board while energized.
Moreover, fi x the heat sink to the board temporarily.
There is a possibility that protecting is generated when these work 
is not done.

NOTE  OF  REPLACING  THE  IC580  AND  IC590  ON  
THE  AMP  CTRL  BOARD  AND  THE  COMPLETE  AMP  
CTRL  BOARD 
When IC580 and IC590 on the AMP CTRL board and the com-
plete AMP CTRL board are replaced, it is necessary to spread the 
compound (THERMAL COMPOUND G747) (Part No. J-2501-
221-A) between the AMP CTRL board and the heat sink.
Spread the compound referring to the fi gure below.

You can check the status of wireless 
transmission between the main unit and 
subwoofer.

Turns green.

The system is turned on, 
wireless transmission is 
activated and sound signals are 
being received.

Turns orange.

The system is turned on, 
wireless transmission is 
activated with the Secure Link 
function, and sound signals are 
being received.

Flashes green 
quickly.

The wireless transceiver is not 
inserted correctly into the 
wireless transceiver slot.

Flashes green 
or orange 
slowly.

Wireless transmission is 
deactivated.

Turns red.

The subwoofer is in standby 
mode while the system is in 
standby mode or wireless 
transmission is deactivated.

Turns off.

The subwoofer is turned off.

Flashes red.

The subwoofer’s protection is 
active.

CAPACITOR  ELECTRICAL  DISCHARGE  PROCESSING
When checking the board, the electrical discharge is necessary for 
the electric shock prevention.
Connect the resistor to both ends of respective capacitors.
