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)

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  THE  S-AIR  COMMUNICATION  CONFIRMING
EZW-RT10A of the attachment is necessary for the confi rmation of 
S-AIR communication.
Confi rm S-AIR after inserting EZW-RT10A in the set (AIR-
SA17Ti).

DIRECTION  OF  EZW-RT10A  INSTALLATION
When EZW-RT10A is install with theTX-IF board detached of the 
set, the label of EZW-RT10A is the under and install.
