Notes on chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be
damaged by heat.
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 viscou-s (sticky, less prone to flow)
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.

ADCC FACTORYTEST MODE
ADCC Factory Test mode have two stages:
1. ADCC DSP Data Line Checking
2. ADCC AUTO CAL MIC board Checking
Factory Test System Setup
1. When power off :
Press the three buttons < + DISPLAY + ?/1 .
(If it doesn’t operate, please press DISPLAY again afetr 2
seconds.)
Afterward, press the DIMMER to start DCAC factory test
mode.
1. ADCC DSP Data Line Checking
After press the DIMMER , DCAC Factory test mode will start,
below display will show:
“DCAC[][][]x” x = 1, 2, 3
If there is error happen, below display will show:
“ERR[]SD0x” x = 1 → D1112 or R1198 or C1523 problem
x = 2 →D1113 problem
x = 3 →D1114 problem
2. ADCC AUTO CAL MIC board Checking
Connect front left speaker of the receiver and AUTO CAL
microphone. Turn MASTERVOLUME jog, there will be test tone
sound output from front left speaker, and the display will change
accordingly.
“AD[]-[]xxx” xxx = 0 to 255(dependson loudness of test tone)
