Cautionary Notes
Before beginning the procedure, please read
through this document. The matters described may
differ according to the model.
No User Data
This product cannot save user data. Backing up user data during servicing is
not required.
Parts List
A 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 Diagram
In 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.

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.
4.
1 flash:

10. Residual Noise Check
fig.DD-7-wave-8.eps_75
Make the connections shown below to the INPUT and OUTPUT jacks on the
DD-7.
1.
INPUT A:
Connect a 47-kΩ dummy plug.
INPUT B:
Connect a 47-kΩ dummy plug.
OUTPUT A:
Connect a noise meter (JIS-A) and monitor speaker.
OUTPUT B:
Connect a noise meter (JIS-A) and monitor speaker.
Adjust the MODE knob to the ANALOG position.
Verify that the CHECK LED goes dark.
Verify that residual noise is -93.0 dB or less.
Verify that no audible noise or shock noise is present.
2.
Adjust the MODE control to the REVERSE position.
Verify that the CHECK LED lights up orange.
Verify that residual noise is -99.0 dB or less.
Verify that no audible noise or shock noise is present.
3.
Detach the plugs from the INPUT A and INPUT B jacks and switch off
the power.
11. Battery Operation Check
1.
Insert batteries into the battery compartment, connect the AC adaptor (to
INPUT A), and switch on the power.
Make sure the CHECK LED lights up.
2.
Rapidly disconnect the AC adaptor and verify battery operation.
* Failing to disconnect rapidly triggers a reset. If reset occurs repeatedly, a
problem such as faulty contact in the AC adaptor jack may be present. If the
CHECK LED is dark, check the battery voltage.
