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.

You can clear all memorized settings and 
revert the receiver back to the factory default 
settings by performing the following 
procedure. This procedure can also be used to 
initialize the receiver before you use it for the 
first time.

Press ?/1 to turn off the 
receiver.

While holding down the TONE 
and 2CH/A.DIRECT, press ?/1 
to turn on the receiver.

The “MEMORY CLEARING...” appears 
on the display window for a while, then 
changes to “MEMORY CLEARED!”
Changes or adjustments made to the 
settings are now reset to the defaults.

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

You can check the status of the receiver by the 
message. See the following to solve the 
problem. If any problem persists, consult your 
nearest Sony dealer.

The receiver is covered and ventilation holes 
are blocked. The receiver will automatically 
turn off after a few seconds. Remove the 
object covering the upper panel of the 
receiver and turn on the power again.

Irregular current is output to the speakers 
due to a short circuit on the speaker 
terminals. The receiver will automatically 
turn off after a few seconds. If the protective 
device on the receiver is activated due to a 
short-circuit problem, turn off the receiver. 
Check the connection of the speakers and 
turn on the power again.

Check that the ventilation hole on the top of 
the receiver is not blocked.

See “Network Update” to update the  
receiver to a newer software version.

s If you use the receiver in the main zone, 

connect the receiver to a TV via an HDMI 
cable.

s If you connect the receiver to a TV via a 

video cord, set “Playback Resolution” to 
“480i/576i”.

s If you connect the receiver to a TV via a 

component video cord, set “Playback 
Resolution” to a parameter appropriate to 
your TV.

Refer to SUPPLEMENT-1 for the MAIN board of printed wiring 
board, schematic diagram and electrical parts list of Taiwan mod-
el.
Refer to SUPPLEMENT-2 for the AMP_CONNECT-1, D-VIDEO, 
E-VOL, PROTECTOR_FC, PROTECTOR_FH, PROTECTOR_
SR, SUB_D-VIDEO and USB-DDC boards of printed wiring board, 
schematic diagram and electrical parts list of Taiwan model.

The USB-CONNECT board installed in AEP and UK models has been 
deleted in the midway of production, and the D-AUDIO and USB-DDC 
boards have been changed into connection with the wire.
Note: Taiwan model does not use USB-CONNECT board in the fi rst time 

of production, and the D-AUDIO and USB-DDC boards are con-
nection with the wire.
