1 ABOUT LEAD FREE
SOLDER (PbF)
Distinction of PbF PCB:
PCBs (manufactured) using lead free solder will have a PbF
stamp on the PCB.
Caution :
•
•
Pb free solder has a higher melting point than standard
• •
solder; Typically the melting point is 50 - 70°F (30 40°C) higher. Please use a soldering iron with
temperature control and adjust it to 700 ± 20°F (370 ±
10°C). In case of using high temperature soldering iron,
please be careful not to heat too long.
•
•
Pb free solder will tend to splash when heated too high
• •
(about 1100°F/600°C)
•
•
This lead free solder will be used for the products after
• •
serial No. 1,000,001.

4 REPLACING THE FUSE
Use fuses of the same specified rating (15amps). Using
different substitutes or fuses with higher ratings, or connecting
the product directly without a fuse, could cause fire or damage
to the stereo unit.
5 MAINTENANCE
Your product is designed and manufactured to ensure a
minimum of maintenance. Use a dry, a soft cloth for routine
exterior cleaning. Never use benzine, thinner or other solvents.
6 NOTES
[RADIO BLOCK]
Do not align the AM/FM package block. When the package
block is necessary, it will be supplied already aligned at the
factory.
[CD DECK BLOCK]
This model has no servo alignment points because
microcomputer controls the servo circuit.

LIST
Notes :
1. Be sure to make your orders of replacement parts
according to this list.
2. Important safety notice: Components, identified by
have special characteristics important for safety. When
replacing any of these components, use only
manufacturer´s specified parts.
3. Location keys in the remarks column indicates the general
location of the parts shown in the exploded drawing, as in a
road map.
4. The marking (RTL) indicates that Retention Time is limited
for this item. After the discontinuation of assembly in
production, the item will continue to be available for a
specific period of time. The retention period of availability is
dependent on the type of assembly, and in accordance with
the laws governing part and product retention. After the end
of this period, the assembly will no longer be available.
•
•
Order intake period is basically six months after the first
• •
shipment.
