Data Backup - Yamaha DD-50 Owner's Manual

Thank you for purchasing the Yamaha DD-50. The DD-50 has been developed to
act and play like a drum set but with greater ease. Before you use the instru-
ment, we recommend you to read through this manual.
Taking Care of Your DD-50
Your DD-50 will give you years of playing pleasure if you follow the simple rules given below:
Location
Do not expose the instrument 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 the instru-
ment is not in use.
An AC adaptor, if used (the DD-50 runs from
either batteries or an optional AC adaptor),
should be unplugged from the AC outlet if
the instrument is not to be used for an ex-
tended period of time.
Unplug the AC adaptor during electric
storms.
Avoid plugging the AC 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, operation errors, and possibly dam-
age.
Turn Power OFF When Making
Connections
To avoid damage to the instrument and other
devices to which it is connected, turn the
power switches of all related devices OFF
prior to connecting or disconnecting cables.
Handling and Transport
Never apply excessive force to the controls,
connectors or other parts of the instrument.
Congratulations!
YAMAHA is not responsible for damage caused by improper handling or operation.
Always unplug cables by gripping the plug
firmly, not by pulling on the cable.
Disconnect all cables before moving the
instrument.
Physical shocks caused by dropping, bump-
ing, or placing heavy objects on the instru-
ment 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
instrument (vinyl can stick to and discolor the
surface).
Electrical Interference
This instrument contains digital circuitry and
may cause interference if placed too close to
radio or television receivers. If this occurs,
move the instrument further away from the
affected equipment.

Data Backup

Custom data and some settings (see page 21)
will be retained in memory even if the power
switch is turned OFF as long as an AC power
adaptor is connected or batteries are installed.
Service and Modification
The DD-50 contains no user serviceable parts.
Opening it or tampering with it in anyway can
lead to irreparable damage and possibly
electric shock. Refer all servicing to qualified
YAMAHA personnel.
