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  OF  REPLACING  THE  IC3111, IC3511, IC3513  
AND  IC3514  ON  THE  D-VIDEO  BOARD
IC3111, IC3511, IC3513 and IC3514 on the D-VIDEO board 
cannot exchange with single. When these parts are damaged, ex-
change the complete mounted board.

NOTE  OF  REPLACING  THE  IC3601  ON  THE  D-VIDEO  
BOARD
Replacement of IC3601 on the D-VIDEO board used in this unit 
requires a special tool.

NOTE  OF  REPLACING  THE  IC101,  IC304,  IC501  AND  
IC2503  ON  THE  NETWORK  BOARD
IC101, IC304, IC501 and IC2503 on the NETWORK board cannot 
exchange with single. When these parts are damaged, exchange the 
complete mounted board.

NOTE  OF  REPLACING  THE  IC106,  IC107,  IC206  AND  
IC207  ON  THE  NETWORK BOARD
Replacement of IC106, IC107, IC206 and IC207 on the NET-
WORK board used in this unit requires a special tool.

MODEL  IDENTIFICATION
Distinguish the model by AC OUTLET connector on back panel.
