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)

Hooking up the system
1
Attach the reflector to the speakers. 
(See fig. A.)
2
(See fig. B for steps 2 through 4.)
Connect the left speaker cord 8 pin plug to the rear
panel jack with their respective arrows aligned.
3
Connect the subwoofer to the wall outlet.
4
Connect the CD walkman, PC, etc., to the INPUT
jack on the left speaker.
5
Position the speakers. 
(See fig. C.)
Listening to the sound 
(see fig. D)
First, turn down the volume on the left speaker. The volume
should be set to minimum before you begin playing the
programme source.
1
Press POWER on the left speaker.
The POWER indicator lights up green.
For the European models
Press POWER on the subwoofer to turn it on, and then
press OPERATE on the left speaker.
The OPERATE indicator lights up green.
The main power source of the system is provided by the
subwoofer. When the power of the subwoofer is turned off,
the system does not operate, even if OPERATE is pressed.
2
Rotate INPUT to select 1/2.
You can enjoy the mixed sound from INPUT 1 and 2.
3
Play the programme source.
To adjust the volume
Rotate VOLUME.
To adjust the subwoofer
Rotate BASS to adjust the bass volume.
Set the volume level to best suit your preference according to the
programme source.
Using the headphones/earphones
Connect the headphones/earphones to the PHONES jack.
Notes
• To enjoy high-quality sound, do not turn the BASS
volume too high.
• When using the headphones, you cannot adjust the bass
volume.
Troubleshooting
Should you encounter a problem with your speaker system, check
the following list and take the indicated measures. If the problem
persists, consult your nearest Sony dealer.
There is no sound from the speaker system.
• Make sure all the connections have been correctly made.
• Make sure the volume on the left speaker and the connected
component have been turned up properly.
• Check if headphones are connected. If they are, disconnect them.
There is distortion in the subwoofer sound output.
• Turn down the volume level on the connected component. Or,
if the connected component has the bass boost function, set it to
off.
• Rotate BASS on this unit to reduce the bass volume.
There is hum or noise in the speaker output.
• Make sure all the connections have been correctly made.
• Make sure none of the audio components are positioned too
close to the TV set.
The sound has suddenly stopped.
Make sure all the connections have been correctly made.
