Fields
Avoid locations exposed to direct sunlight or other sources of heat. Also avoid
locations subject to vibration, excessive dust, cold or moisture.
Do not attempt to clean the exterior with chemical solvents, as this may damage
the finish. Clean with a soft, dry cloth.
Do not open the cabinet or attempt to make your own repairs or modifications to
any part of the instrument. Such actions may not only result in electrical shock or
damage, but will also void the product warranty. Refer all servicing to a qualified
Yamaha service center.
When moving the instrument be sure to unplug the AC mains cord as well as all
other connecting cables.
Avoid applying excessive force to switches and slide controls, dropping or rough
handling. The DX27 is ruggedly constructed using reliable solid-state circuitry,
nonetheless it is a fine instrument that should be treated with care.
Digital circuitry such as that used in the DX27 is sensitive to voltage spikes and
surges. Because of this, the DX27 should be turned off and unplugged from the
AC power outlet in the event of an electrical storm.
Digital circuitry is also sensitive to electromagnetic fields such as those produced
by television sets, radio receivers, transmitters, transceivers, etc. The DX27 should
be kept at least several feet from such sources in order to prevent possible random
malfunctions.
