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
Fig. A)

SERVICING NOTES

ADVANCE PREPARATION WHEN CONFIRMING OP­ERATION

All of the units included in the HT-CT260H (SA-CT260H/SA­WCT260H) are required to confi rming operation of SA-CT260H.
Check in advance that you have all of the units.

ABOUT PART REPAIR OF EACH BOARD

When mounted parts on each board installed by this unit are defec­tive, replace the complete mounted board.
However the U701 on the MAIN board is exchangeable. Refer to
“ELECTRICAL PARTS LIST” (page 40) for U701.

CAPACITOR ELECTRICAL DISCHARGE PROCESSING

When checking the board, for the electric shock prevention, con­nect the resistors to both ends of respective capacitor (CE502) to
discharge the capacitor (CE502).

NOTE OF REPLACING THE WS T BOARD

When the WS T board is exchanged, you must perform linking
between SA-CT260H and SA-WCT260H.

Linking method:

This operation requires a remote commander.

You can link the Sound Bar (SA-CT260H)
and the subwoofer (SA-WCT260H) again
to enable wireless transmission between
them.

1

Press LINK on the rear of the
subwoofer with the point of a
pen, etc .

The subwoofer keeps beeping for
a certain time. Perform steps 2 to 5
before the subwoofer stops
beeping.

2 Press AMP MENU.
3

Select “WS” with (select),
then press .

4

Select “LINK,” then press .

5 “START” appears, then press .

“SEARCH” appears, and the Sound
Bar searches for equipment that
can be used with Link. Proceed to
the next step within 1 minute.
To quit the Link function during a
search for equipment, press

.
When subwoofer is linked with the
Sound Bar, the

indicator on
the subwoofer lights up in green
and the subwoofer beeps once.
“OK” appears on the front panel
display.
If “FAILED” appears or the
subwoofer does not stop beeping,
perform the process again from
ste p 1.
