• All of the units included in the SWF-BR100 (wire-
less transceiver: UWT-BR100, Audio cable), and
the TV corresponding to SWF-BR100 are required
to confirming operation of SWF-BR100.
Check in advance that you have all of the units.
Refer to the operating instructions of the SWF-
BR100 or operating instructions of the TV corre-
sponding to SWF-BR100 for the operation method.

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.
SAFETY CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication
is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
of a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V AC range are suitable. (See

SECTION 1
SERVICING NOTES
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 flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
ADVANCE PREPARATION WHEN CONFIRMING OP-
ERATION
All of the units included in the SWF-BR100 (wireless transceiver:
UWT-BR100, Audio cable), and the TV corresponding to SWF-
BR100 are required to confirming operation of SWF-BR100.
Check in advance that you have all of the units.
Refer to the operating instructions of the SWF-BR100 or operat-
ing instructions of the TV corresponding to SWF-BR100 for the
operation method.
NOTE OF PERFORMING THE OPERATION CHECK IN
THE STATE THAT HEAT SINK WAS REMOVED
When performing the operation check in the state that this unit was
disassembled, it is possible to perform the operation check in the
state that heat sink was removed. But don’t perform the operation
check in the long time, and perform the operation check in the
volume state as low as possible.
NOTE OF REPLACING THE IC104 ON THE MAIN
BOARD AND THE COMPLETE MAIN BOARD
When IC104 on the MAIN board and the complete MAIN board
are replaced, it is necessary to spread the compound (G747) be-
tween the MAIN board and the heat sink.
Spread the compound (G747) referring to the figure below.

CAPACITOR ELECTRICAL DISCHARGE PROCESSING
When checking the board, for the electric shock prevention, con-
nect the resistors to both ends of respective capacitor (C936) to
discharge the capacitor (C936).
