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; this may damage the
finish. Clean with a soft, dry cloth.
Do not open the FB-01 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 wall plug and all other
connecting cables.
Avoid applying excessive force to switches and slide controls, dropping, or rough
handling. The FB-01 is ruggedly constructed and uses reliable solid-state circuitry,
but it should be treated with the same care you would give to any other fine musical
instrument.
Digital circuitry, such as that used in the FB-01, is sensitive to voltage spikes and
surges. Be sure to remove all connecting cables during an electrical storm.
Digital circuitry is also sensitive to electromagnetic fields such as those produced
by television sets, radio receivers, transmitters, etc. The FB-01 should be kept several
feet away from any such sources to prevent possible malfunctions.

The Exclamation point within an equila-
teral triangle is intended to alert the user
to the presence of important operating
and maintenance (servicing) instructions
in the literature accompanying the pro-
duct.
The lightning flash with arrowhead sym-
bol, within an equilateral triangle, is in-
tended to alert the user to the presence
of uninsulated "dangerous voltage"
within the product's enclosure that may
be of sufficient magnitude to constitute
a risk of electric shock to persons.
