About Ground Terminal
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,
video equipment 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.

Unsuitable places for connection
• Water pipes (may result in shock or electrocution)
• Gas pipes (may result in fire or explosion)
• Telephone-line ground or lightning rod (may be dangerous in the event of lightning)
* Once the connections have been completed (p. 11), turn on power to your various devices in the
order specified. By turning on devices in the wrong order, you risk causing malfunction and/or
damage to other devices.
* This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is
required before the unit will operate normally.
* Always make sure to have the volume level of audio output devices turned down before
switching on power. Even with the volume all the way down, you may still hear some sound
when the power is switched on, but this is normal, and does not indicate a malfunction.
Make sure the power cable is securely inserted, then slide the [POWER] switch located
on the rear panel to [ON]. The indicators on the front panel flash in sequence from left to
right, and the VC-30HD starts up.
