paper as required.
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.

Selecting Test Items
Verify the version.
Indication of the version of the VE-2 follows the following rules.
Tests 2 through 5 1 through 4 must be conducted in sequence.
•
The light and dark pattern of the 7 LEDs indicates the version
number.
After tests 2 through 5 1 through 4 have been completed, tests 6 through

•
Lights: o, dark: - (Note that this is the opposite of the usual
indication.)
Pressing AUTO HARMONIST enters the test-item selection mode.
•
The leftmost LED indicates the units’ place.
When in this mode, turn the TYPE knob to change the flashing pattern of
the LEDs above the TYPE knob, and then press VARIATION.
•
