SECTION  1
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.
NOTE  OF  REPLACING  THE  IC403  ON  THE  MAIN  
BOARD
IC403 on the MAIN board cannot exchange with single. When this 
part is damaged, exchange the entire mounted board.

FACTORY  SETTING
Procedure:
1.  Press the [
?/1
] button to turn the power on.
2.  Press three buttons of the [
N
], [
X
], and [
?/1
] simultaneously.
3.  The message “INITIALIZE?” is displayed on the liquid crystal 
display, and press the [VOLUME –] button.
4.  The main power is turned off, and the data of the built-in data 
fl ash memory is initialized.
5.  Press the [
?/1
] button to turn the power on.

Procedure:
1.  Press the [
?/1
] button to turn the power on.
2.  Press three buttons of the [COUPLING], [PAIRING], and 
[
N
] simultaneously.
3.  Then all segments of liquid crystal display are turned on. The 
display changes in order of the all segments of are turned on 
→ test pattern 1 → test pattern 2 → all segments of are turned 
on... whenever the [
x
] button is pressed.
4.  Press the [PRESET –] button, the version of the micro control-
ler is displayed on the liquid crystal display.
5. Press the [

tantalums.
•  All resistors are in Ω and 1/4 W or less unless otherwise 
specifi ed.
•      f  : Internal component.
•  C : Panel designation.
THIS  NOTE  IS  COMMON  FOR  PRINTED  WIRING  BOARDS  AND  SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
•  A : B+ Line.
•  Voltages and waveform are dc with respect to ground un-
der no-signal (detuned) conditions.
  no mark : POWER ON
•  Voltages are taken with VOM (Input impedance 10 M
Ω).
  Voltage variations may be noted due to normal production 
tolerances.
•  Waveform is taken with a oscilloscope.
  Voltage variations may be noted due to normal production 
tolerances.
•  Circled number refer to waveform.
