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,  
IC3514  AND  IC3601  ON  THE  D-VIDEO  BOARD
IC3111, IC3511, IC3513, IC3514 and IC3601 on the D-VIDEO 
board cannot exchange with single. When these parts on the D-
VIDEO board are damaged, exchange the entire mounted board.

NOTE  OF  REPLACING  THE  IC5002  AND  IC5202  ON  
THE  DSP  BOARD
IC5002 and IC5202 on the DSP board cannot exchange with sin-
gle. When these parts on the DSP board are damaged, exchange the 
entire mounted board.

NOTE  OF  REPLACING  THE  IC8001,  IC8005  AND  
IC8013  ON  THE  NETWORK  BOARD
IC8001, IC8005 and IC8013 on the NETWORK board cannot ex-
change with single. When these parts on the NETWORK board are 
damaged, exchange the entire mounted board.

UPDATE  OF  SOFTWARE  OF  IC2513  ON  THE  CON-
TROL  BOARD,  IC3610  ON  THE  D-VIDEO BOARD  AND  
IC5208  ON  THE  DSP  BOARD
Perform operation of the following when the update of software 
of the IC2513 on the CONTROL board, IC3610 on the D-VIDEO 
board and IC5208 on the DSP board are necessary.

•  IC2513 on the CONTROL board, IC3610 on the D-VIDEO 

board and IC5208 on the DSP board

Procedure:
1.  Connect J1499 on the MAIN board and PC by using the RS-

232C cable.

2.  Turn on the main power.
3.  The update is executed by using PC.
4.  When the update ends, turn off the main power.
5.  Remove the RS-232C cable from the J1499 on the MAIN 

board and PC.

Before using the receiver for the first time, 
initialize the receiver by performing the 
following procedure. This procedure can also 
be used to return settings you have made to 
their factory defaults.

POWER

TONE MODE

HDMI IN

If there is a malfunction, the display shows a 
code of two numbers and a message. You can 
check the status of the system by the message. 
See the following table to solve the problem. If 
any problem persists, consult your nearest 
Sony dealer.

Irregular current is output to the speakers, or 
the upper panel of the receiver is covered 
with something. The receiver will 
automatically turn off after a few seconds. 
Check the connection of speakers and turn 
on the power again.

For other messages, refer to “Operating 
instrustions”.

After “MEMORY CLEARING...” 
appears on the display for a while, 
“MEMORY CLEARED.” appears.
All the settings you have changed or 
adjusted are reset to the initial settings.

It takes about 30 seconds for the memory to be 
cleared completely. Do not turn the receiver off until 
“MEMORY CLEARED.” appears on the display.
