Notes on chip component replacement
• 
Never reuse a disconnected chip component.
• 
Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
SAFETY  CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, 
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE  TEST
The AC leakage from any exposed metal part to earth ground and 
from all exposed metal parts to any exposed metal part having a 
return to chassis, must not exceed 0.5 mA (500 microamperes.). 
Leakage current can be measured by any one of three methods.
1.  A commercial leakage tester, such as the Simpson 229 or RCA 
WT-540A. Follow the manufacturers’ instructions to use these 
instruments.
2.  A battery-operated AC milliammeter. The Data Precision 245 
digital multimeter is suitable for this job.
3.  Measuring the voltage drop across a resistor by means of a 
VOM or battery-operated AC voltmeter. The “limit” indication 
is 0.75 V, so analog meters must have an accurate low-voltage 
scale. The Simpson 250 and Sanwa SH-63Trd are examples 
of a passive VOM that is suitable. Nearly all battery operated 
digital multimeters that have a 2 V AC range are suitable.  (See 
Fig. A)

SERVICING  NOTES
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.
Checking the transmission status
You can check the status of sound transmission between the S-AIR main
unit and surround amplifier by checking the POWER/ON LINE indicator
on the surround amplifier.
POWER/ON
LINE indicator
Status
Turns green
Sound transmission is established.
Flashes green
Sound transmission is not established. For details, see
“Troubleshooting”.
Turns red
The surround amplifier does not output sound. For details,
see “Troubleshooting”.
Turns off
The surround amplifier turns off or its protection is active.
For details, see “Troubleshooting”.
Sound
There is no sound.
Check the status of the POWER/ON LINE indicator on the surround
amplifier.
– turns green
• The speaker cord is not connected securely.
• Check the speaker connections and settings.
• The volume of the S-AIR main unit is set to minimum.
• The S-AIR main unit is in mute status.
• Depending on the source or the settings of the S-AIR main unit, the effect of the
speakers may be less noticeable.
• Headphones are connected.
– flashes green
• The S-AIR main unit is not turned on.
• The S-AIR main unit is paired to another S-AIR product.
• The surround amplifier is paired to another S-AIR main unit.
• Confirm the IDs of the S-AIR main unit and surround amplifier.
• Pairing operation is not completed.
• Sound transmission is poor. Move the
surround amplifier so that the POWER/ON LINE indicator turns green.
• Move the system away from any other wireless products.
• Stop using another wireless product.
• The wireless transceiver and/or the wireless transmitter are/is not inserted
correctly.
– turns red
• Change the SURROUND SELECTOR switch (SURROUND or SURROUND
BACK) of the surround amplifier to match the S-AIR main unit.
