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. 19) in the Service Notes and save the data. After completing the procedure, restore the backed-up data to the product.

Part ReplacementWhen 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 ListA 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 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.
