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)

GENERAL

instruction manual.
Precautions
On safety
The nameplate indicating operating voltage, power
consumption, etc. is located on the bottom exterior.
• Before operating the system, be sure that the operating voltage
of the system is identical with that of your local power supply.
Where purchased
Operating voltage
U.S.A./Canada
120 V AC, 60 Hz
European countries
220-230 V AC, 50Hz
Other countries
• 110 – 120 V AC, 50/60Hz
• 220 – 230 V AC, 50 Hz
• The unit is not disconnected from the AC power source (mains)
as long as it is connected to the wall outlet, even if the unit
itself has been turned off.
• Unplug the system from the wall outlet if it is not to be used for
an extended period of time. To disconnect the cord, pull the
cord by grasping the plug. Never pull the cord itself.
• Should any liquid or solid object fall into the system, unplug
the system’s power cord and have the system checked by
qualified personnel before operating it any further.
• The AC power cord should be changed only at a qualified
service shop.
• For efficient heat dissipation, ensure there is sufficient space to
the rear of the woofer. Also, avoid placing objects on the unit.
On operation
• Do not drive the speaker system with a continuous wattage
exceeding the maximum input power of the system.
• Contact between bare speaker wires at the speaker terminals
may result in a short-circuit.
• Before connecting, turn off the Speaker system, the PC and the
audio component to avoid damaging the speaker system.
• The volume level should not be turned up to the point of
distortion.
Hooking up the system
1
(See fig. A for steps 1 through 3.)
Connect the left speaker cord 8 pin plug to the rear
panel jack with their respective arrows aligned.
2
Connect the subwoofer to the wall outlet.
3
Connect the CD walkman, PC, etc., to the INPUT
jack on the left speaker.
4
Position the speakers. 
(See fig. B.)
Note on connecting
Do not connect an output device to INPUT 1 and INPUT 2
of the unit at the same time (as shown in fig. C) to avoid
damage to the output device.
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
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.
Notes
• To enjoy high-quality sound, do not turn the bass
volume too high.
• When two units are connected to the system and the
programme sources are played at the same time, their
playback sounds will be mixed up. In this case, turn off
one of the units not in use.
