1.1 NOTES ON SOLDERING
1.2 NOTES ON REPLACING
1.3 SERVICE NOTICE
• 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.
Do NOT use a soldering iron whose tip temperature cannot be controlled.
The part listed below is difficult to replace as a discrete component part.
It the failure of suspected that are listed in the table, replace whole ASSY.

• Performance pad was calibrated when the product is produced. If a relevant part is replaced with a new one, be sure to
carry out the calibration.
• For the method of calibration, refer to "PAD CALIBRATION MODE" in "6.1 TEST MODE".
• If you forget to carry out the calibration, power for tapping the performance pad and degree of sound volume when
the sampler velocity mode is turned ON vary depending on the pad.
• Calibration execution data is memorized in the MAIN ASSY. Be sure to carry out the calibration when the MAIN ASSY is
replaced new one.
Calibration of performance pad
• Don`t touch the black parts of the PADB ASSY (side-A) and black mat parts of the Sensor (16 pieces each, which are
pressure sensitive ) with your bare hands.
Clear the dust between the PADB ASSY, Sheet, Sensor and Button by air blast when you assemble the sensor.
About PADB ASSY of sensors (Pressure sensitive)
• Clear the dust between inside of the Cap, Buttons and PCBs by air blast to remove the foreign particles when you assemble
SEQB ASSY or BARB ASSY.
Caution: Control Panel and Chassis unit in the state that has wire does not open 180 degrees.
About SEQB ASSY and BARB ASSY
• Replacement of the NAND (IC1200) in the MAIN ASSY is not possible during service, because writing of the MAC address
on the production line is required. Therefore, the NAND (IC1200) are not supplied as a service part. If the NAND is defective,
replace the whole MAIN ASSY.

The fuse F1 is in the neutral, and that the mains shall be disconnected to de-energine the phase conductors.
To avoid receiving the electrical shock, operator needs to discharge the voltage (electrical charge) of primary side.
As an example, show the way of using the "discharge JIG" below.
About DWR1548 (SW POWER SUPPLY)
Fuse notice (For Skilled Person - base on IEC62368-1)
Since primary side of SW POWER SUPPLY remains high voltage (bigger than 200 V) for a long time after power off, it's very
dangerous. (Reason : Because electrical capacitor of C4/C5 can stock much electrical charge, but discharge need a long time.)
And more, since operator can touch the dangerous primary side easily, there is some possibility that operator receives an
electrical shock from SW POWER SUPPLY.
NOTE: DJS-1000 keeps compliance "safety regulation" as a set. This is applied to only engineer and service person and so on.
Red area below is the dangerous area that operator can touch easily and receives an electrical shock.
Primary side electrical shock
Electrical shock area of A-side.
Electrical shock area of B-side.
After connecting JIG to C4 or C5 lead wire,
If C4/C5 is dangerous condition, JIG LEDs turn on.
(Luminance of LEDs is variable.)
If C4/C5 is safety condition, JIG LEDs turn off completely.
The circuit of "discharge JIG" is shown below.
• All Resisters are 10k ohm(3W).
• Both of LED is LTL17KRH5D
Checking
LEDs
No polarity
C4
C5
When there is no right "discharge JIG", take measures
the following method.
• Step1: After the power is turned off,wait 2 minutes.
• Step2: Connect the Register Jig and leave the unit
as it is, for 10 seconds.

[Prior Confirmation]
(1) Confirmation of the internal wiring materials
Confirm that the wiring materials of the relevant parts are inserted properly. Also, confirm that there is no disconnection in the wiring materials.
Inset the wiring materials properly if they are not. Or, replace the wiring materials if they are disconnected. (See overall wiring diagram)
(2) Confirmation of the power supply
Confirm that the voltage of the power supply that is used in the part to be diagnosed is not abnormal.
If it is abnormal, identify the power generation source based on the power supply map and make the necessary repairs.
(3) Confirmation of the reset signal
Confirm that the reset signal of the IC that is used in the part to be diagnosed is Hi (Released).
If it is abnormal, identify the reset signal generation source based on the circuit diagram and make the necessary repairs.
(4) Confirm that there is no problem in the display/ operation systems
Confirm that there is no problem in the displays/ operations in the test mode.
If a problem is found, make the necessary repairs on the target part. (See Display Trouble and Operation Trouble flow charts)
Activate it in the normal mode and supply the audio signal to the INPUT terminal
Adjust the INPUT LEVEL knob to the appropriate position
