SAFETY CHECK-OUT
After correcting the original service problem, perform the following 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

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 leadfree 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.
• 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 OPERATION
All of the units included in the HT-CT180 (SA-CT180/SAWCT180/Remote control) are required to confirming operation of
SA-CT180. Check in advance that you have all of the units.

ABOUT PARTS REPAIR OF EACH BOARDS
When each boards installed in this unit are defective, individual
electrical parts that the mount is done cannot be replaced. When
each boards are defective, replace the mounted board or the whole
parts including an applicable board.
Printed wiring board and schematic diagram that have been described on this service manual are for reference.
(Printed wiring board and schematic diagram of WIERLESS board
have not described)
NOTE OF REPLACING THE BT NFC BOARD OR THE
NFC MODULE
When replacing the BT NFC board or the NFC module, be sure to
replace both at the same time.
The BT NFC board or the NFC module cannot replace with single.
METHOD OF RESET
If the system still does not operate
properly, reset the system as follows:
1
2
While holding down the @/1 (on/
standby) button on the system,
hold down the INPUT and VOL –
buttons simultaneously for 5
seconds.
All 5 indicators on the Bar Speaker
flash 3 times, and the settings
return to their initial status.
Disconnect the AC power cord
(mains lead).
WHAT TO DO IF PROTECT
If all of the LEDs are lit, it is state in the protect. This state shows
an abnormality of the AMP circuit.
In this case, there is a possibility that the MAIN board is defective.
Please replace the MAIN board.
NOTE OF REPLACING THE WIRELESS BOARD
When replaced the WIRELESS board, link of SA-CT180 and SAWCT180 will be disconnected.
Before you return repaired unit to customers, please link the SACT180 and SA-WCT180 by the following procedure.
If, in a state in which only one of SA-CT180 or SA-WCT180 is
brought into service field, and replaced the WIRELESS board of
SA-CT180 or SA-WCT180, when returning the repaired unit, be
sure to inform the customers that it is necessary to link the following procedure.
Enabling the Secure Link
function
You can specify the wireless connection
to link the Bar Speaker to the subwoofer
using the Secure Link function. This
function can help prevent interference if
you use multiple wireless products or
your neighbors use wireless products.

2
Press LINK on the rear of the
subwoofer.
You will hear beeps from the
subwoofer.
Hold down PAIRING on the Bar
Speaker for 5 seconds, then VOL –
for 5 seconds.
The OPTICAL and ANALOG
indicators flash alternately.
When the Bar Speaker is linked to
the subwoofer, the indicators stop
flashing.
If it failed, the indicators light up for
5 seconds. Try again the above
operation.

reset is complete, all LEDs light off and becomes the standby
status.

Initial value for demo mode:
Function
: OPTICAL
Volume
: 25
Muting
: OFF
Sound field
: CLEAR AUDIO+
Night mode
: OFF
Voice
: OFF
Subwoofer volume : 10
Dual mono
: MAIN
Note 1: When demo mode is “ON”, the operation of the [@/1] button on
the unit, and the operation of the [@/1] and [INPUT] buttons on
the remote commander is invalid.
Note 2: When the non-operation and no sound for five minutes is followed, setting will return to the initial value for demo mode.
Releasing method:
Perform the “FACTORY RESET”.
Note: The demo mode does not release by unplug the AC cord.
