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.

ADVANCE  PREPARATION  WHEN  CONFIRMING  OP-
ERATION
When the operation of the TA-SA200WR is confi rmed, it is nec-
essary to communicate the set of main unit with S-AIR and TA-
SA200WR and confi rm.
Confi rm the main unit with S-AIR, TA-SA200WR and EZW-RT10 
etc. are prepared beforehand when you repair.

DIRECTION  OF  EZW-RT10/RT10A  INSTALLATION
When EZW-RT10/RT10A is install with the AMP board detached 
of the set, the label of EZW-RT10/RT10A is the under and install.

You can check the status of sound 
transmission between the S-AIR main unit 
and surround amplifier by checking the 
S-AIR/STANDBY indicator on the 
surround amplifier.

Turns green.

The system is turned on, 
wireless transmission is 
activated and surround 
signals are transmitting.

Flashes green 
quickly.

The system is turned on 
and wireless transmission 
is activated, but surround 
signals are not 
transmitting.

Flashes green 
slowly.

The system is turned on 
and wireless transmission 
is deactivated.

Turns red.

The surround amplifier is 
in standby mode while the 
system is in standby mode 
or wireless transmission is 
deactivated.

Turns off.

The surround amplifier is 
turned off.

Flashes orange.

The wireless transceiver is 
not connected to the 
surround amplifier.

Flashes red.

The surround amplifier’s 
protection is active.

There is no sound.
Check the status of the S-AIR/STANDBY 
indicator on the surround amplifier.
– Turns off.

s Check that the AC power cord (mains lead) of 

the surround amplifier is connected securely.

s Turn the surround amplifier on by pressing 

"/1 on the surround amplifier.

– Flashes orange.

s Check that the wireless transceiver is inserted 

into the surround amplifier correctly.

– Flashes green quickly.

s Change the S-AIR ID settings of the S-AIR 

main unit and surround amplifier.

cWhen you use this system with surround 

speakers:

s Set the SURROUND SELECTOR switch of 

the surround amplifier to SURROUND.

cWhen you use this system with surround 

back speakers:

s Set [Surround Back] in [Speaker Settings] of 

the S-AIR main unit to [Yes]. For details, 
refer to the operating instructions of the 
S-AIR main unit.

– Flashes red.

s Press 

"/1 to turn off the surround amplifier, 

and check the following items.

1 Are the + and – speaker cords short-

circuited?

2 Is anything blocking the ventilation 

holes of the surround amplifier?

After checking the above items and fixing 
any problems, turn on the surround amplifier. 
If the cause of the problem cannot be found 

even after checking all the above items, 
consult your nearest Sony dealer.

– Flashes green slowly or turns red.

s Confirm the S-AIR IDs of the S-AIR main 

unit and surround amplifier.

s Confirm the pairing setting.
s Sound transmission is poor. Move the 

surround amplifier so that the S-AIR/
STANDBY indicator turns green.

s Move the system away from other wireless 

devices.

s Avoid using any other wireless devices.

– Turns green.

s Check the speaker connections and settings.
s Depending on the source or the settings of the
