Precautions

Precautions
!! PLEASE READ THIS BEFORE PROCEEDING !!
Location
Do not expose the QY300 to the following condi-
tions to avoid deformation, discoloration, or
more serious damage.
• Direct sunlight (e.g. near a window).
• High temperatures (e.g. near a heat source, out-
side, or in a car during the daytime).
• Excessive humidity.
• Excessive dust.
• Strong vibration.

Power Supply

• Turn the power switch OFF when the instrument
is not in use.
• The power supply cord should be unplugged
from the AC outlet if the instrument is not to be
used for an extended period of time.
• Unplug the instrument during electric storms.
• Avoid plugging the instrument into the same AC
outlet as appliances with high power consump-
tion, such as electric heaters or ovens. Also avoid
using multi-plug adaptors since these can result
in reduced sound quality and possibly damage.
Turn Power OFF When
Making Connections
• To avoid damage to the instrument and other de-
vices to which it is connected (a sound system,
for example), turn the power switches of all re-
lated devices OFF prior to connecting or discon-
necting audio and MIDI cables.
iv
MIDI Connections
• When connecting the QY300 to MIDI equip-
ment, be sure to use high-quality cables made
especially for MIDI data transmission.
• Avoid MIDI cables longer than about 15 meters.
Longer cables can pick up electrical noise that
can causes data errors.
Handling and Transport
• Never apply excessive force to the controls, con-
nectors or other parts of the instrument.
• Always unplug cables by gripping the plug
firmly, not by pulling on the cable.
• Disconnect all cables before moving the instru-
ment.
• Physical shocks caused by dropping, bumping, or
placing heavy objects on the instrument can re-
sult in scratches and more serious damage.
Cleaning
• Clean the cabinet and panel with a dry soft cloth.
• A slightly damp cloth may be used to remove
stubborn grime and dirt.
• Never use cleaners such as alcohol or thinner.
• Avoid placing vinyl objects on top of the instru-
ment (vinyl can stick to and discolor the surface).
Electrical Interference
• This instrument contains digital circuitry and
may cause interference if placed too close to ra-
dio or television receivers. If this occurs, move
the instrument further away from the affected
equipment.
