Handling
Choose
the
installation
location for the
DX5
with
caution.
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
wilt
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
DX5
is
ruggedly constructed using
reliable solid-state
circuitry,
nonetheless
it
is
a fine
instrument
that
should be
treated
with
care.

Electromagnetic
Fields
Digital circuitry
such
as that
used
in
the
DX5
is
sensitive to voltage spikes
and
surges.
Because
of
this,
the
DX5
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
DX5
should
be kept
at least
several
feet
from such sources
in
order
to
prevent possible
random
malfunctions.
