Important Notes on Installation
Before installing the board, switch off the power to the
equipment and unplug the power cord from the power outlet.
Remove only the specified screws.
Be careful not to let removed screws fall into the unit.
After you have removed the panel, cover, and screws, do not
leave them off. When you have finished installing the option
board, be sure to reattach the panel, cover, and screws.
Be careful not to cut your hand on the opening for installing the
board.
After installation, if the unit fails to power up when you switch
on the power, contact your Roland Service Station.
To avoid the risk of damage to internal components that can be
caused by static electricity, please carefully observe the
following whenever you handle the board.
Before you handle the circuit board, first touch the front panel
of the AR-3000R, and while maintaining contact with the front
panel, pick up the circuit board. This discharges any static
electricity that has accumulated in your body and clothing.
When handling the board, grasp it only by the panel or the
board’s edges. Avoid touching any of the electronic
components or connectors.
