In this Service Notes, the older type is called the BF-3, and the newer type is called the BF-3A. Both have Flange

After identifying the type of the product being serviced, refer to the corresponding Service Notes for information on required parts and test methods. B

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

10、 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 w
