NOTE  OF  REPLACING  THE  CN103  CN104,  IC103,  
IC107,  L251  AND  L254  ON  THE  MAIN  BOARD
CN103 CN104, IC103, IC107, L251 and L254 on the MAIN board 
cannot exchange with single. When these parts are damaged, ex-
change the entire mounted board.
NOTE  OF  REPAIRING  THE  TOUCH  KEY  BOARD
The mount parts on the TOUCH KEY board installed in this set 
cannot exchange with single. When the TOUCH KEY board is de-
fective, exchange the entire FRONT PANEL ASSY.
NOTE  OF  REPAIRING  THE  MOTHER  BOARD
The mount parts on the MOTHER board installed in this set cannot 
exchange with single excluding a part of parts. When the mount 
parts that have not been described in electrical parts list are dam-
aged, exchange the entire mounted board.
NOTE  OF  REPLACING  THE  MOTHER  BOARD
When replacing the MOTHER board, MAC address is changed. 
Print the following explanation, cut it, and hand over it to the cus-
tomer with the set, when returning the set that the repair is com-
pleted to the customer.
MAC address of the main unit has been changed by this repair.
When using the MAC address fi ltering function of connection destina-
tion access point equipment, set it again.
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.
