Precautions to Observe When
Attaching the Rack Mount
Hardware
• Use the proper size Phillips head screwdriver for the screw
heads (No. 2 driver). Use of a screwdriver that does not fit the
screw heads may result in the heads becoming stripped.
• When removing the screws, turn the screwdriver in the
counterclockwise direction. To tighten the screws, turn the
screwdriver in the clockwise direction.
• Remove only the specified screws when attaching the rack
mount hardware.
• Once the installation is complete, check it again to make sure
that is has been done correctly.
• When turning the unit upside-down, get a bunch of newspapers
or magazines, and place them under the four corners or at both
ends to prevent damage to the buttons and controls. Also, you
should try to orient the unit so no buttons or controls get
damaged.
• When turning the unit upside-down, handle with care to avoid
dropping it, or allowing it to fall or tip over.
1.
Before attaching the rack mount hardware, turn the power
off to the V-440HD and all connected devices and
disconnect all power cords and connection cables.
2.
Turn the V-440HD over and remove the screws specified in
the following figure to remove the rack mount hardware.
3.
Return the screws removed in Step 2 to their original holes
and secure.
Loss of air flow due to dust accumulating at the exhaust vent may
inhibit the forced cooling function. Using a vacuum cleaner or other
means, regularly remove accumulations of dust from the exhaust
vent and intake vent.
Malfunctioning of the fan will prevent the forced cooling function
from working properly, posing the danger of overheating and other
problems. If you cannot confirm that the fan is operational, please
consult your Roland dealer or a Roland ED Service Station.
