Cautionary Notes

Before beginning the procedure, please read

through this document. The matters described may
differ according to the model.

Back Up User Data!

User data may be lost during the course of the procedure. Refer to Data
Backup and Restore Operations (p. 16) in the Service Notes and save the
data. After completing the procedure, restore the backed-up data to the
product.

Part Replacement
When replacing components near the power-supply circuit or a heat-
generating circuit (such as a circuit provided with a heat sink or including a
cement resistor), carry out the procedure according to the instructions with
respect to the part number, direction, and attachment position (mounting so as
to leave an air gap between the component and the circuit board, etc.).

Parts List
A component whose part code is ******** will not 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).
• Because it is carried in electronic data on the Roland web site.
• Because it is a package or an accessory irrelevant to the function
maintenance of the main body.
• Because it can be replaced with an article on the market. (battery or etc.)

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.

There are cases that the circuit diagrams are omitted. This omission will
happen to the highly integrated digital circuit boards (e.g. Main Board etc) that
are virtually impossible to repair nor analyze.

Roland Japan Warranty

Please send the problem report with followings when the defect occurred
within one year from production and within one month from the first
customer’s purchase.

• Model name:
• Serial number:
• Version:
• Purchase date by the first customer: yyyy/mm/dd
• Symptom:
• Frequency: always, sometimes or seldom
• Confirmed the symptom at your service dept: Yes/No

Please send the problem report to rjasc@roland.co.jp.

Disassembly Procedure
1. Hold down the protrusion on the back of the Bottom Case and lift slowly until the stand rises.

2. Use the tip of a pen, paperclip, or the like to push the protrusion on the right Side Panel and separate the Boutique Dock from the unit.

3. Remove all screws (x 8) securing the Module Case from underneath. (Plain View (p. 8), a and c in View 2)

4. Lift the Module Case and disconnect the connectors (x 2).

5. Detach the Module Case.

Now the Main Board, Panel Board and Sub Board can be detached.

6. Remove all screws (x 3) securing the Module Case from the rear side. (Plain View (p. 8), a in View 1)
Now the Panel Escutcheon can be detached.

Important Notes on Assembly

When shaping the battery wirings, give attention to the following points.

1. Lead out two wirings to the rear side of the unit (in the direction of the
allow as shown in the figure).
fig.assemble-1.eps

2. Fix them at two locations with acetate tape (#40122812).

* Make sure that the wirings do not touch the terminal of the battery.
