1. SERVICE PRECAUTIONS
1.1 NOTES ON SOLDERING
1.2 CAUTION
• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.
• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.
Do NOT use a soldering iron whose tip temperature cannot be controlled.
Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).
The following lead-free solders are available as service parts:
• Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

1. Operate TX and RX in Normal Mode.
2. When you set TX to Factory Mode from the state of 1
above, RX also automatically enters Factory Mode.
• How to shift from Factory Mode to Normal Mode
1. After Factory Mode is entered, once turn the power off
(setting TX to Standby status and RX to AC OFF status).
2. When you turn TX and RX back on, they enter Auto
Pairing Mode then shift to Normal Mode after several
seconds.
2. Normal Mode
• Normal operation status
• The LED indications are as follows:
• This mode can be entered in the following conditions:
1. When TX and RX are turned on in Factory Mode (The ID
of RX is changed to that of TX.)
2. When TX and RX are turned on with the same ID.
• This mode can be entered in the following conditions:
1. When only TX is in Power ON status while RX is in
Power OFF status
2. When only RX is in Power ON status while TX is in
Standby status
3. When TX and RX differ in ID although both are in Power
ON status
3. Standby Mode
• Status where TX and RX are searching for each other
• The LED indications are as follows:
4. Re-Pairing (Manual Pairing) Mode
• Mode to normally operate TX and RX differing in ID.

Pairing with TX is as follows:
2. After the above-mentioned TX enters Re-Pairing Mode
(green LED blinking) with the Power Cord of RX
disconnected, connect the AC power to RX.
-> If pairing with TX fails: RX enters Standby Mode 15
seconds after it is turned on (red LED ON).
-> When pairing with TX is successful: RX immediately
enters Normal Mode (green LED ON).
• If Re-Pairing is started for TX in Factory Mode
1. The green LED blinks at intervals of 250 ms.
2. Re-Pairing Mode is maintained for 60 seconds at
maximum. The mode changes to Standby Mode after 60
seconds (red LED ON).

5.3 SPECIFICATIONS FOR THE PROTECTION CIRCUITS
Protection Activation Conditions for the Sound Bar Adapter
On the Protection Functions of the Sound Bar
On the Protection Functions of the Subwoofer
The DC output from the adapter will be shut off if the 24-V DC output load becomes 6.4 A (max. current limitation) or
higher (based on 90-V AC power).
1. Protection Activation Conditions for the TAS5342A
• Max. current limitation: 7.1 A or higher
• /OTW: If the temperature becomes 125 °C or higher, the Over Temperature Protection function will be activated.
• /SD: In a case of undervoltage or overload, the Shutdown Protection will be activated.
In a case of excess current or excess temperature at the AMP IC (IC702: STA326), the protection function will be
activated then deactivated in the AMP IC, according to the internally set programmable recovery time (100 ms), as shown
below:
1) After a shutdown, the PWM output will be OFF for 100 msec (the set recovery time).
2) The system will enter Normal mode to detect operating conditions.
3) If the condition that caused the shutdown still remains, the protection function will be reactivated, according to the set
recovery time.
No LED display nor power-off operation will be activated in the subwoofer while the protection function is activated.
Therefore, if no sound is output even if the LED is lit in green, the protection function may have been activated.
2. Over Temperature Protection (MICOM Pin 88)
• In Normal Operation mode: High
In a case where the temperature of the AMP IC (IC122 or IC123) becomes 125 °C or higher: Low
The signal from Pin 14 of IC120 (TAS5508) is set to low in order to mute the PWM output.
Muting of the PWM output is canceled when /OTW is returned to high.
3. On the AMP Shutdown Protection Function (AMP IC [IC122, IC123] Pin 5) (/SD)
• In Normal Operation mode: High
• In a case of undervoltage or overload: Low
When this signal is input to the MICOM, the audio signal will be muted and the system will enter STANDBY mode.
