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.
NOTE FOR DISASSEMBLY
Lithium ion battery is installed in this unit.
When disassembling this unit, be sure to disassembly after remov-
ing the connector of lithium ion battery from board.

NOTE OF REPLACING THE ELECTRICAL PARTS ON
EACH BOARD FOR REPAIRING
Among mounted electrical parts on each board, only parts that are
described in the electrical parts list can be replaced for repairing.
The parts that are not described in the electrical parts list cannot be
replaced with single for repairing.
In that case, replace the complete mounted board.
Printed wiring board and schematic diagram that have been de-
scribed on this service manual are for reference.
NOTE OF REPLACING THE BT BOARD OR THE NFC
BOARD
When replacing the BT board or the NFC board, be sure to replace
the BT board and the NFC board simultaneously.
The BT board or the NFC board cannot replace with single.
Among the repair parts, the BT board and the NFC board are sup-
plied as one unit.

RESETTING THE SYSTEM
If the system doesn’t respond and
cannot be operated despite the power
being on, reset the system using the
RESET button.
1 Press RESET on the rear of
the unit with a pin or other
pointed object.
The system will turn off.
2 Press Æto turn the system
back on.
Notes
• If the system doesn’t turn back on, consult
your Sony dealer.
• Pairing information is not deleted when
you press RESET.
CHARGING THE BATTERY
The system can be used with the
built-in battery (rechargeable) instead
of connecting the AC power cord to
a wall outlet if the battery has been
sufficiently charged.
Connect the AC power cord
(supplied) to the AC IN jack on
the rear of the unit, and then to
the wall outlet.
ʭAC power cord (supplied)
ʮTo wall outlet
The CHARGE indicator will light up in
amber. Charging will be completed in
about 4 hours and the indicator will turn
off.
Notes
• It may take longer to charge the battery
depending on the conditions of use.
• Even if you do not intend to use the
system for a long time, charge the battery
to its full capacity once every six months
to maintain its performance.
• In an extremely cold or hot environment,
charging stops for safety.
If charging is taking a long time, this also
stops the system from charging.
In these conditions, the CHARGE indicator
continues to flash quickly in amber, but
this is not a malfunction.
To resolve these issues, disconnect the
AC power cord and connect it again in an
operating temperature between 5°C and
35°C (41°F and 95°F).
Hint
You can operate the system while it is
charging.
