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.
ADVANCE PREPARATION WHEN CONFIRMING OPER-
ATION
All of the units included in the HT-S500RF (SA-WS500RF/SS-
S500RF/SS500RF/Remote control) or HT-S700RF (SA-WS700RF/
SS-S700RF/SS700RF/Remote control) are required to con
fi
rming
operation of SA-WS500RF/WS700RF. 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.

NOTE OF PERFORMING THE OPERATION CHECK IN THE
STATE THAT HEAT SINK OR FAN MOTOR 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 board. However, don’t perform
the operation check in the long time, and perform the operation
check in the volume state as low as possible.
It is possible to perform the operation check in the state that fan mo-
tor is removed from board.
ABOUT THE PROTECTION
“PRTCT” appears in the front panel
display of the subwoofer, the sound
is muted, and buttons on the
remote control or subwoofer other
than
Æ
(power) do not work.
q
The protection feature is activated.
Press
Æ
(power) to turn the system
off and disconnect the AC power cord
(mains lead) and check the items
below.
– Make sure that the ventilations of
the subwoofer are not covered and
turn on the system after a while.
– When the system is using the USB
connection, remove the USB device
and turn on the system. If the
system operates properly, the
current of the connected USB device
is over the maximum output current
of the system 500 mA, or the USB
device may have an abnormality.
