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.
13
■ 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.

Power Supply
The Personal Studio ST7 can be operated with battery or AC power.
Always turn the power OFF when making AC power connections or replacing batteries.
Using a Power Adaptor
Please use the supplied power adaptor. *(adaptor not included in some countries)
1. Plug the DC output cable from the adaptor into the
DC10-12V jack q on the top panel. (See the Illus. above)
2. Plug the AC adaptor into a convenient wall AC power
socket.
When using an AC adaptor, use the supplied AC
adaptorPA-1D to power the ST7. The use of an
incompatible adaptor may result in irreparable
damage, or cause fire. The use of an incompatible
adaptor may also void the warranty. Please use
caution.
Using Batteries
1.
Open the battery compartment, located on the back
panel of the ST7.
2. Insert six AAA size 1.5V batteries taking careful
note of the polarity markings as shown in the
illustration above.
Place the batteries on top of the ribbon for easy
removal at a later date.
3. Replace the battery compartment cover.
When the AC adaptor is connected, battery power
is automatically disconnected. However, poor
connection of the AC adaptor or power cable will
result in power being drawn from the batteries.
It is recommended that batteries be replaced early.
Run down batteries will result in the following:
1 Reverb does not function properly.
2 Earphone sound is unstable.
3 Noise becomes audible.
When one of these symptoms appears, take note of the
cautions below and replace the used batteries with a
complete set of new batteries.
● Make sure to follow polarity indications on the battery compartment
when replacing batteries. Improper insertion may result in fire.
● Always replace worn batteries with a complete set of new batteries. NEVER
mix old and new batteries! Do not mix different types of batteries (alkaline,
manganese), or batteries from different makers, or different battery types
by the same maker. Doing so may result in fire!
● To prevent possible damage to the unit due to battery leakage and
unnecessary power drain, remove the batteries from the unit if it is not to
be used for an extended period of time.

■ The AUX IN jack
The ST7’s AUX IN jack !2 can be used to connect an external
stereo signal source to the ST7. Connecting a CD player,
tape recorder, etc. to the AUX IN jack with an audio cable
allows you to play along with an external audio source.
The AUX IN jack’s !2 signal level is controlled by the AUX
IN VOLUME o control.
■ The LINE OUT Jack
The ST7’s LINE OUT jack !3 delivers the stereo signal of
the ST7 for connection to a stereo mixing console or tape
recorder for listening by external speakers or recording.
● Make sure that the power of the ST7 and any external
equipment is turned OFF before making any
connections. Also, set the volume of any external
audio sources to the minimum level before
connecting. A high volume setting could result in
damage to the equipment, hearing impairments or
electrical shock.
● The AUX OUT jack signal must never be returned to
the AUX IN jacks, either directly or through external
equipment. Doing so will result in the production of
feedback, and damage to the internal unit.
