(see figure) is facing up. Connecting the AC adapter to a power outlet makes the indicator light up.

Cord Hook
To prevent the inadvertent disruption of power to your unit (should the plug be pulled out accidentally), and to avoid applying
undue stress to the AC adaptor jack, anchor the power cord using the cord hook, as shown in the illustration.

Caution Regarding the Power Supply
Depending on the circumstances of a particular setup, you may experience a discomforting sensation, or perceive that the
surface feels gritty to the touch when you touch this device, microphones connected to it, or the metal portions of other objects.
This is due to an infinitesimal electrical charge, which is absolutely harmless. However, if you are concerned about this, connect
the ground terminal (see figure) with an external ground. When the unit is grounded, a slight hum may occur, depending on the
particulars of your installation. If you are unsure of the connection method, contact the nearest Roland Service Center, or an
authorized Roland distributor, as listed on the "Information" sheet.
