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 leadfree 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 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.

ELECTRICAL ADJUSTMENTS
DP-IF3000
Notes:
1. These adjustments are performed in the order that they are described.
2. Adjustment and measurement are performed for each channel
unless otherwise specified.
3. Adjustment is made for the left channel first and then the right
channel.
4. The power voltage is supplied with 9V.
Oscillation Frequency Adjustment
setting:

counter
IF board
TP513 (L-ch)
TP514 (R-ch)
+
Adjustment method:
• Perform this adjustment without signal.
1. S202(INPUT SELECT) is set on the DIGITAL side, and there
is no input signal in IC001(DIGITAL IN)(to set the mute state).
Note:
Adjustment can’t be done any more because the luminosity of
LED stops when condition without an input signal lasts for more
than ten minutes.
Move S202(INPUT SELECT) to the ANALOG side, and move ATT
SW(S051) in your making LED light sent out again.
2. Connect a digital frequency counter to TP513 for L-ch and
TP514 for R-ch on the IF board.
3. Adjust L503 (L-ch) and L501 (R-ch) on the IF board so that
the reading on the digital frequency counter is each within 2.3
MHz (L-ch) and 2.8 MHz (R-ch).

2. Connect a digital volmeter to TP513 for L-ch and TP514 for
R-ch on the IF board.
3. Adjust RV501 (L-ch) and RV502 (R-ch) on the IF board so
that the reading on the digital volmeter is 490mV.
Specified Value:
L-chRV501487.5 to 492.5 mV
