SERVICING NOTES

DSX-A30
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead­free 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.
NOTE FOR THE 15-PIN CONNECTOR (CN001)
Do not use alcohol to clean the 15-pin connector (CN001) connect­ing the front panel with the main body. Do not touch the connector directly with your bare hand. Poor con­tact may be caused.
ABOUT CHECKING THE OPERATION
When checking the operation of this unit, connect a USB device to this unit. Refer to the support site written in the operating instruction for the details about the compatibility of a USB device.
