SAFETY CHECK-OUT
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 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 2V AC range are suitable. (See
Fig. A)
To Exposed Metal
Parts on Set
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Unleaded solder
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350°C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow) than
ordinary solder so use caution not to let solder bridges occur such
as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH
MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS

SECTION 2
TEST MODE
FACTORY PRESET MODE
* All preset contents are reset to the default setting.
* Procedure:
While depressing the FM MODE and the PRESET TUNING
buttons simultaneously, press the ?/1 button again. The message
“FACTORY” appears and the present contents are reset to the
default values.
AM CHANNEL STEP 9 KHZ/10 KHZ
SELECTION MODE
* Either the 9 kHz step or 10 kHz step can be selected for the AM
channel step.
* Procedure:
Set the FUNCTION to AM. Turn off the main power.
While depressing the TUNING+ button or the
PRESET TUNING + button, press the ?/1 button to turn on
the main power. Either the message “9 k STEP” or “10 k STEP”
appears. Select the desired step.
SPEAKER SIZE SELECTION MODE
*Either Normal Speaker or Micro Satellite Speaker can be selected.
*Procedure:
While depressing the MAIN MENU button, press the ?/1 button
to turn the main power.
Either the message “NORM. SP.” or “MICRO SP.” is displayed.
Select the desired speaker size.
FLUORESCENT INDICATOR TUBE TEST MODE
* All fluorescent segments are tested. When this test is activated,
all segments turn on at the same time, then each segment turns on
one after another.
* Procedure:
While depressing the FM MODE and the MD/TAPE buttons
simultaneously, press the ?/1 button to turn on the main power.

as VIDEO2 , DVD , MD/TAPE , CD and TUNER FM/AM can
be used.)
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 2CH button, press the ?/1 button to turn
on the main power.
The message “SF. CLR.” appears and initialization is performed.

* Procedure:
While depressing the MUSIC and the TUNINGbuttons
simultaneously, press the power ?/1 button to turn on the main
power.
“REST 25” appears.
Every pressing of any button other than ?/1 counts down the
buttons. The buttons which are already counted once are not
counted again. When all buttons are pressed “REST 00” appears.
