SAFETY CHECK-OUTAfter 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 TESTThe 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 Fig. A)

TABLE OF CONTENTS

SECTION 1SERVICING NOTES

UNLEADED SOLDERBoards 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 MARKUnleaded 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-ERATIONAll of the units included in the HT-CT180 (SA-CT180/SA-WCT180/Remote control) are required to confi rming operation of SA-CT180. Check in advance that you have all of the units.

ABOUT PARTS REPAIR OF EACH BOARDSWhen 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 de-scribed 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 MODULEWhen 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.

WHAT TO DO IF PROTECTIf 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 BOARDWhen replaced the WIRELESS board, link of SA-CT180 and SA-WCT180 will be disconnected.Before you return repaired unit to customers, please link the SA-CT180 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 fi eld, 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 follow-ing procedure.

Enabling the Secure Link functionYou 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.

1 Press LINK on the rear of the

subwoofer.

You will hear beeps from the

subwoofer.

2 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.

METHOD OF RESETIf the system still does not operate

properly, reset the system as follows:

1 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.

2 Disconnect the AC power cord

(mains lead).

VERSION DISPLAYThe check of the software version can be performed.

Procedure:1. Press the [@/1] button to turn the power on.2. Press three buttons of the [INPUT], [VOL+] and [VOL−] si-

multaneously for 2 seconds.3. When enter the version display mode, the software version is

shown by the frequency of blinking of each LED.

Software versionX.XX

Minor version (Lower) (BLUETOOTH function LED)

Minor version (Upper) (ANALOG function LED)Major version (OPTICAL function LED)

Example: When the software version is “1.02” OPTICAL function LED is blink once. ANALOG function LED is not blink. BLUETOOTH function LED is blink twice.

4. When the version display is fi nished, return to the normal mode.

FACTORY RESETIt can clear all settings and the Bluetooth pairing history to initial conditions. Execute this mode when returning this unit to the cus-tomer.

Procedure:1. Press the [@/1] button to turn the power on.2. Press three buttons of the [INPUT], [VOL−] and [@/1] simulta-

neously for 5 seconds.3. Blink three times all LEDs, then lights up all LEDs. When the

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

DEMO MODEThe demo mode can be performed.(This mode is used by shop front)

Procedure:1. Press the [@/1] button to turn the power on.2. Press two buttons of the [INPUT] and [VOL−] simultaneously

for 5 seconds.3. When enter the demo mode, ANALOG function LED is blink

twice quickly, then changed to the setting of initial value for demo mode.

blink twice quickly

Initial value for demo mode:Function : OPTICALVolume : 25Muting : OFFSound fi eld : CLEAR AUDIO+Night mode : OFFVoice : OFFSubwoofer volume : 10Dual 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 fi ve minutes is fol-lowed, 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.
