BF-3(T) |
|
|
|
|
The BF-3(T) exists in two types that have different circuit structures. In this Service Notes, the older type is called the BF-3, and the newer type is called the BF-3A. Both have Flanger BF-3 inscribed on the pedal and appear at a glance to be completely identical, but they can be distinguished as indicated in the following table.

SERVICE NOTES 2ND EDITION (#17058043E1) |
This version of Service Notes is for the BF-3A.
Before beginning the procedure, please read through this document. The matters described may differ according to the model.
User Data Cannot Be Backed Up
The setting for the sleep mode is saved on the Main Board even when the power has been switched off, but neither verification of its status (ON or OFF) nor backing up the setting is possible. When the Main Board has been replaced, the sleep mode is returned to its default (ON). For more information about the sleep mode, refer to About Sleep Mode (Owner’s Manual, p. 14). No user data other than the setting for the sleep mode is saved.
Part Replacement
When replacing components near the power-supply circuit or a heatgenerating 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.
