Earth Ground
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" indica-
tion is 0.75V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-
amples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2V AC range are suit-
able. (See Fig. A)
1. Check the area of your repair for unsoldered or poorly-sol-
dered connections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
"pinched" or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularly transis-
tors, that were installed during a previous repair. Point them
out to the customer and recommend their replacement.
4. Look for parts which, though functioning, show obvious signs
of deterioration. Point them out to the customer and recom-
mend their replacement.
5. Check the line cord for cracks and abrasion. Recommend the
replacement of any such line cord to the customer.
6. Check the B+ voltage to see it is at the values specified.
7. Check the antenna terminals, metal trim, "metallized" knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:

Precautions
On safety
Should any solid object or liquid fall into the cabinet,
unplug the speaker system and have it checked by
qualified personnel before operating it any further.
On power sources
·AC power cord must be changed only at the qualified
service shop.
·Before operating the speakers, check that the operating
voltage is identical with your local power supply. The
operating voltage is indicated on the nameplate on the
rear of the speakers.
·The unit is not disconnected from the AC power
source as long as it is connected to the wall outlet, even
if the unit itself has been turned off.
·If you are not going to use the speakers for a long time,
be sure to disconnect the speakers from the wall outlet.
To disconnect the AC power cord, grasp the plug itself;
never pull the cord.
On placement
· Do not install the appliance in a confined space, such
as a bookcase or built-in cabinet.
· Do not place the speakers near heat sources, or in a
place subject to direct sunlight, excessive dust or
mechanical shock.
· Good ventilationis essential to prevent internal heat
buildup. Place the speakers in a location with adequate
air circulation, and in a way that does not block the
rear ventilation holes.
On operation
·When turning on or off the subwoofer or other
equipment, lower the volume of the subwoofer to
minimum.
·To avoid damaging the subwoofer:
Be careful in setting the volume control of the
subwoofer to avoid an excessive input power.
Do not open the enclosure or remold speaker units
and networks.
The grillnet is not removable. Do not remove it.
On the speaker system
Although this speaker system is magnetically shielded,
there may be cases where the picture on some TV sets
becomes magnetically distorted. In such a case, turn off
the power of the TV set once, and after 15 to 30 minutes
turn it on again.
If there seems to be no improvement, locate the
speaker system further away from the TV set. Also, be
sure not to place objects in which magnets are attached
or used near the speaker system, such as audio racks, TV
stands, and toys. These may cause magnetic distortion to
the picture due to their interaction with the system.
On cleaning
Clean the cabinet, panel and controls witha soft cloth
slightly moistened with a milddetergent solution. Do
not use any type of abrasive pad, scouring powder or
solvent such as alcohol or benzine.
If you have any question or problem concerning your
speaker system, please consult your nearest Sony dealer.
