    Cautionary Notes

    Before beginning the procedure, please readthrough this document. The matters described maydiffer according to the model.

    No User DataThis product cannot save user data. Backing up user data during servicing is

    not required.

    Parts ListA component whose part code is ******** cannot be supplied as a service part

    because one of the following reasons applies.

    Because it is supplied as an assembled part (under a different part code).

    Because a number of circuit boards are grouped together and supplied as

    a single circuit board (under a different part code).

    Because supply is prohibited due to copyright restrictions.

    Because reissuance is restricted.

    Because the part is made to order (at current market price).

    Circuit DiagramIn the circuit diagram, NIU is an abbreviation for Not in Use, and

    UnPop is an abbreviation for Unpopulated. They both mean non-mounted

    components. The circuit board and circuit board diagram show silk-screened

    indications, but no components are mounted.

    Verifying the VersionNumber

    1. Connect an AC adaptor.

    2. Turn down all controls all the way counterclockwise.

    3. Holding down the foot pedal and inserting a plug into the INPUT jack

    makes the CHECK LED light up.

    * Continue holding down the pedal until the LED goes dark.

    After approximately 2 seconds, the CHECK LED goes dark.

    * The CPU and DSP checks are performed before the LED goes dark as just

    described. If a problem is found in the CPU, DSP, or the like, the LED may not

    go out.

    After approximately 1 second the CHECK LED flashes, and the number

    of flashes indicates the version.

    1 flash: Ver. 1.00

    2 f lashes: Ver. 1 .01

    3 f lashes: Ver. 1 .02

    4. After the version display, execution shifts to the Test Mode.

    Performing a Factory Reset

    This product has no factory-reset feature.

    Updating the System

    5. Depress the toe of the EV-5 pedal all the way.

    Verify that the CHECK LED is lighted up red.fig.DD-7-wave-1.eps_75

    6. Unplug the EV-5 from the jack.

    6. DSP Through Check (INPUT B Check)

    Make the connections shown below to the INPUT and OUTPUT jacks on the

    DD-7, using the settings indicated.INPUT A: Input a rectangular wave at 400 Hz, 800 mVp-p.

    INPUT B: Input a rectangular wave at 400 Hz, 800 mVp-p.

    OUTPUT A: Connect the oscilloscope.

    OUTPUT B: Connect the oscilloscope.

    Set the oscilloscope to 500 mV/DIV, 1 ms/DIV, and coupling: DC.

    1. Adjust the MODE control to the 200 ms position.

    Verify that the CHECK LED goes dark.fig.DD-7-wave-1.eps_75

    2. Disconnect the plug from the INPUT B jack.

    Verify that the CHECK LED lights up green.fig.DD-7-wave-4.eps_75

    If the waveforms grow larger, operation is correct. If the waveforms

    show no change, operation is faulty.

    3. Insert the plug into the INPUT B jack.

    INPUT B: Input a rectangular wave at 400 Hz, 800 mVp-p.

    OUTPUT A: Connect the oscilloscope.

    OUTPUT B: Connect the oscilloscope.

    Set the oscilloscope to 500 mV/DIV, 1 ms/DIV, and coupling: DC.

    1. Adjust the MODE control to the 50 ms position.

    Verify that the CHECK LED lights up orange.fig.DD-7-wave-1.eps_75

    2. Disconnect the plug from the INPUT A jack.

    Verify that the CHECK LED lights up red.fig.DD-7-wave-5.eps_75
