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 sol-

der;  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.

Replacing the Fuse

Use fuses of the same specified rating 15 amps. Using different
substitutes  or  fuses with  higher ratings, or connecting  the unit
directly without a fuse, could cause fire or damage to the stereo
unit.

1.4.

Maintenance

Your  product  is  designed  and  manufactured  to  ensure  a  mini-
mum of maintenance. Use a dry, a soft cloth for routine exterior

cleaning. Never use benzine, thinner or other solvents.

1.5.

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 fac-
tory.

[CD DECK BLOCK]

This model has no servo alignment points because microcom-

puter controls the servo circuit.
