• Before connecting the instrument to other electronic components, turn off the
power for all components. Before turning the power on or off for all
components, set all volume levels to minimum. Also, be sure to set the
volumes of all components at their minimum levels and gradually raise the
volume controls while playing the instrument to set the desired listening level.
•When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners,
solvents, cleaning fluids, or chemical-impregnated wiping cloths.
• Do not insert a finger or hand in any gaps on the instrument.
• Never insert or drop paper, metallic, or other objects into the gaps on the
panel. If this happens, turn off the power immediately and unplug the power
cord from the AC outlet. Then have the instrument inspected by qualified
Yamaha service personnel.
• Do not place vinyl, plastic or rubber objects on the instrument, since this
might discolor the panel or keyboard.
• Do not rest your weight on, or place heavy objects on the instrument, and do
not use excessive force on the buttons, switches or connectors.
• Do not operate the instrument for a long period of time at a high or
uncomfortable volume level, since this can cause permanent hearing loss. If
you experience any hearing loss or ringing in the ears, consult a physician.
Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or destroyed.
Always turn the power off when the instrument is not in use.
Even when the power switch is in the “STANDBY” position, electricity is still flowing to the instrument at the minimum level. When you are not using the instrument for a
long time, make sure you unplug the AC power adaptor from the wall AC outlet.
Removing rubber stoppers for rack mount installation The i88X has four removable rubber stoppers. If the i88X does not fit in your rack mount cabinet
because the stoppers hit against another device, remove the stoppers as described below.
Before removing the stoppers, make sure you have a sharp, thin tool — such as a safety pin or straight-
ened paper clip.
Do not use any tool that easily snaps or bends, such as a toothpick or thin wire.
1. Turn the i88X upside down.
2. Insert the tool between the rubber stopper
and the plastic rivet (as shown).
3. Pull the rivet up and out of the panel.
4. Pull out the rubber stoppers.
To re-attach the removed stoppers, reverse the
procedure above, inserting the rivets perpendic-
ularly.
