Your DTX will give you years of reliable service 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, such as near a window.
High temperatures, for example, near a heat
source, outdoors, or in a car during the daytime.
Excessive humidity.
Excessive dust.
Strong vibrations.
Power Supply
Always use the supplied Yamaha AC Adaptor
(PA-1207, PA-3B or an equivalent) to power your
DTX. Other adaptors may cause damage to the
DTX. Also, make sure that the adaptor you have
is appropriate for the AC mains supply voltage in
the area where you intend to use the DTX.
Turn the power OFF and unplug the AC adaptor
when the instrument is not in use.
Unplug the AC adaptor during electrical storms.
Avoid plugging the AC adaptor used with the
DTX into the same AC mains 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 damage.
Turn off the power before making or breaking
connections.
To avoid damage to the instrument and other
devices to which it is connected (a sound system,
for example), always turn the power switches of
all related devices OFF before connecting or
disconnecting audio and MIDI cables.
Handling and Transport
Never apply excessive force to the controls,
connectors, or other parts of the instrument.
Always plug and unplug any cables by gripping
the connector, not the cord itself. Disconnect all
cables before moving the instrument.
Dropping the DTX or otherwise subjecting it to
strong physical shocks can damage it. Handle it
with care.
Cleaning
Clean the cabinet and panel with a soft dry cloth.
A slightly damp cloth may be used to remove
stubborn grime and dirt.
Do not use solvents such alcohol, benzine, or
thinner to clean the cabinet or panel.
Avoid placing vinyl objects on top of the
instrument. Vinyl can stick to and discolor the
surface.
Electrical Interference
The DTX contains digital circuitry and may cause
interference or noise if placed too close to TV
sets, radios, or similar equipment. If such a
problem does occur, move the DTX further away
from the affected equipment.
Memory Back-up
The DTX contains a special long-life battery that
retains the contents of its internal RAM memory
even when the power is turned OFF. The back-
up battery should last for several years. When the
back-up battery needs to be replaced, the
message “ERR-Low battery” will momentarily
appear on the display when you turn the power
ON. When this happens, have the back-up
battery replaced by qualified Yamaha service
personnel.
DO NOT ATTEMPT TO REPLACE THE BACK-
UP BATTERY YOURSELF.
Transfer important data from your DTX to a
MIDI data recorder such as the Yamaha MDF2
MIDI Data Filer for safe long-term storage.
Yamaha cannot be held responsible for data loss
caused by battery failure or improper operation
of the DTX.
Service and Modification
The DTX contains no user-serviceable parts.
Opening the case and/or tampering with the
internal circuitry can lead to irreparable damage
and will void the warranty. Refer all maintenance
to qualified Yamaha service personnel.
Third-party Software
Yamaha cannot take any responsibility for
software produced for this product by third-party
manufacturers. Please direct any comments about
such software to the manufacturer or their
agents.
Yamaha is NOT responsible for damage caused by
improper handling or operation.
