PART NO.
After correcting the original service problem, perform the following safety checks 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
The A C leakage from an y 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 microampers). 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 V OM
or battery-operated A C v oltmeter. 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 2V AC range are suitable. (See Fig. A)

all segments turn on at the same time, then each segment turns on
one after another.
Procedure:
While depressing the FUNCTION MODE button and the SOUND
FIELD MODE button simultaneously, press the 1/u button to
turn on the main power. All se gments turn on at the same time, then
each segment turns on one after another.
When the CURSOR MODE button, B , V , v , or b is pressed,
the indication advances in the following order: All segments on,
Bridge 1, Bridge 2, All segments off.
FACTORY SET MODE
* All preset contents are reset to the default setting.
Procedure:
While depressing the FUNCTION MODE button and the SOUND
FIELD GENRE button simultaneously, press the 1/u button to
turn on the main power. The message F ACTORY SET appears and
the present contents are reset to the default values.
ALL CLEAR MODE
* All preset contents are cleared when this mode is activated. Use
this mode before returning the product to clients upon completion
of repair.
Procedure:
While depressing the SOUND FIELD GENRE button and the
SOUND FIELD ON/OFF buttons simultaneously, press the 1/u
button to turn on the main power. The message “ALL CLEAR!”
appears and the preset data is cleared.
SOUND FIELD CLEAR MODE
* The preset sound field is cleared when this mode is activated.
Use this mode before returning the product to clients upon completion of repair.
Procedure:
While depressing the SOUND FIELD ON/OFF button, press the
1/u button to turn on the main power. The message “SURR
CLEAR!” appears and initialization is performed.
DSP TEST MODE
Procedure:
While depressing the FUNCTION MODE button and the EQUALIZER buttons simultaneously, press the 1/u button to turn on the
main power. The message “DSP NO ERROR” or “DSP ERROR”.
When “DSP NO ERROR” is displayed, a 1 kHz signal is output to
all channels.
When the B , V , v , or b button is pressed while “DSP NO
ERROR” is displayed, the message “DSP TEST MODE” appears.
In this mode, the input signal that is selected by the FUNCTION
knob is distributed to each speaker.

Note:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and 1/

W or less unless otherwise
specified.
• % : indicates tolerance.
• 2 : nonflammable resistor.
• 1 : fusible resistor.
• C : panel designation.
• U : B+ Line.
• V : B– Line.
• H : adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
No mark : FM
• Voltages are taken with a V OM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production tolerances.
• Waveforms are taken with a oscilloscope.
• Circled numbers refer to waveforms.
• Signal path.
