Your ST7 will give you years of reliable service if you follow the
simple rules given below:
■
Location
Do not expose it to the following conditions to
avoid deformation, discoloration, or more
serious damage.
• Direct sunlight (e.g. near a window).
• High temperatures (e.g. near a heat
source, outside, or in a car during the
daytime).
• Excessive humidity.
• Excessive dust.
• Strong vibration.
■
Power Supply
• Turn the power switch OFF when not in use.
• If you use an AC power adaptor, unplug
the adaptor from the AC outlet if not to be
used for an extended period of time.
• Unplug the AC power adaptor during
electric storms.
• Avoid plugging the AC power adaptor into
the same AC outlet as appliances with
high power consumption, such as electric
heaters or ovens. Also avoid using multi-
plug adaptors since these can result in
reduced sound quality and possibly dam-
age.
■
Turn Power OFF When Making Connections
• To avoid damage to the Personal Studio
and other devices to which it is connected
(a sound system, for example), turn the
power switches of all related devices OFF
prior to connecting or disconnecting audio
cables.

■
Handling and Transport
• Never apply excessive force to the
controls, connectors or other parts.
• Always unplug cables by gripping the
plug firmly, not by pulling on the
cable.
• Disconnect all cables before moving
the unit.
• Physical shocks caused by dropping,
bumping, or placing heavy objects on
the unit can result 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 unit (vinyl can stick to and
discolor the surface).
■
Electrical Interference
• This unit contains digital circuitry and
may cause interference if placed too
close to radio or television receivers.
If this occurs, move it further away
from the affected equipment.
YAMAHA is not responsible for damage
caused by improper handling or opera-
tion.
