SAFETY CHECK-OUT
After correcting the original service problem, perform the follow-
ing 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

SECTION 1
SERVICING NOTES
The SERVICING NOTES contains important information for servicing. Be sure to read this section before repairing the unit.
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.
DESTINATION ABBREVIATIONS
The following abbreviations for model destinations are used in this
service manual.

ABOUT PARTS REPAIR OF EACH BOARDS
When each boards installed in this unit are defective, individual
electrical parts that the mount is done cannot be replaced. When
each boards are defective, replace the mounted board or the whole
parts including an applicable board.
Printed wiring board and schematic diagram that have been de-
scribed on this service manual are for reference.
NOTE OF REPLACING THE BT NFC BOARD OR THE
NFC MODULE
When replacing the BT NFC board or the NFC module, be sure to
replace both at the same time.
The BT NFC board or the NFC module cannot replace with single.
WHAT TO DO IF PRTCT IS DISPLAYED
If the “PRTCT” (represents the “PROTECT”) is displayed on the
screen display panel, AMP temperature protection circuit or USB
charging current protection circuit is working.
In this case, there is a possibility that the MAIN board or the USB
board is defective. Be sure to replace the MAIN board and the
USB board at the same time.
METHOD OF RESET
If the system still does not operate
properly, reset the system as follows:
1While holding down the @/1(on/
standby) button on the system,
hold down the INPUT and
VOL (volume) – buttons
simultaneously for 5 seconds.
[RESET] appears on the display, and
the settings of the menu and sound
elds, etc. return to their initial
status.
2Disconnect the AC power cord
(mains lead).
