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 fl ow) 
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.
Notes on chip component replacement
•  Never reuse a disconnected chip component.
•  Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
•  Keep the temperature of soldering iron around 270 °C during 
repairing.
•  Do not touch the soldering iron on the same conductor of the 
circuit board (within 3 times).
•  Be careful not to apply force on the conductor when soldering 
or unsoldering.
Laser component in this product is capable of emitting radiation exceed-
ing the limit for Class 1.
This appliance is classifi ed as a 
CLASS 1 LASER product.
This marking is located on the 
rear or bottom exterior.
CAUTION
Use of controls or adjustments or performance of procedures other than 
those specifi ed herein may result in hazardous radiation exposure.
About This Operating
Instructions
• The instructions in this Operating Instructions
describe the controls on the remote. You can
also use the controls on the unit if they have the
same or similar names as those on the remote.
• The Control Menu items may vary depending
on the area.
• “DVD” may be used as a general term for a
DVD VIDEO, DVD+RW/DVD+R, and DVD-
RW/DVD-R.
• Measurements are expressed in feet (ft) for
North American models.
• The default setting is underlined.
About the S-AIR function
The system is compatible with the S-AIR
function, which allows transmission of sound
between S-AIR products wirelessly.
The following S-AIR products can be used with
the system:
• Surround amplifier: You can enjoy surround
speaker sound wirelessly.
• S-AIR receiver: You can enjoy system sound
in another room.
These S-AIR products can be purchased as an
option (the S-AIR product lineup differs
depending on the area).
Notes or instructions for the surround amplifier
or S-AIR receiver in this operating instructions
refer only to when the surround amplifier or
S-AIR receiver is used.
For details on the S-AIR function, see “Using an
S-AIR Product” (page 83).
