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

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.
