DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON
WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or
expose eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before

About lead free solder /
All of the P.C.B.s installed in this unit and solder joints are
soldered using the lead free solder.
Among some types of lead free solder currently available,
it is recommended to use one of the following types for
the repair work.
• Sn + Ag + Cu (tin + silver + copper)
• Sn + Cu (tin + copper)
• Sn + Zn + Bi (tin + zinc + bismuth)
Caution:
As the melting point temperature of the lead free solder
is about 30°C to 40°C (50°F to 70°F) higher than that of
the lead solder, be sure to use a soldering iron suitable
to each solder.

holes for secure installation. (The front panel unit will
come off easily if its dowels are fitted into dowel holes
without applying quick-drying bond or the like.)
Be sure to initialize the back-up IC after updating
the firmware, otherwise the set up information (tuner
preset, surround mode) can not be memorized
properly.
Start up the self-diagnostic function and select “15.
FACTORY PRESET” menu. (See “SELF-DIAGNOSTIC
FUNCTION”)
Select “15-2. PRESET RSRV” sub-menu and turn off
the power once and turn on the power again. Then
the buck-up IC is initialized.
