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.
