Casio Chord System
The
Casio
Chord
system
has
been
developed
so
you
can
play
the
four
main
types
of
chords
more
easily.
Playing
of
the
chords
is
simplified
as
shown
below:
¢
Pressing
one
of
the
accompaniment
keyboard
keys
produces
a
major
chord
corresponding
to
that
note.
¢
Simultaneously
pressing
any
key
to
the
right
(two
keys
at
the
same
time)
results
in
a
minor
chord.
¢
Similarly,
pressing
one
more
key
to
the
right
(three
keys
in
all)
produces
a
seventh
chord,
and
pressing
the
fourth
key
to
the
right
(four
keys
in
all)
creates
a
minor
seventh
chord.

GUIDELINES LAID DOWN BY FCC RULES
FOR USE OF THE UNIT IN THE U.S.A.
(not applicable to other areas).
This equipment generates and uses radio frequency
energy and if not installed and used properly, that is,
in strict accordance with the manufacturer's instruc-
tions,
may
cause
interference
to
radio
and
television
reception. It has been type tested and found to
comply with the limits for a Class B computing device
in accordance with the specifications in Subpart J of
Part 15 of FCC Rules, which are designed to provide
reasonable protection against such interference
in a residential installation. However, there is no
guarantee that interference will not occur in a
particular
installation.
If
this
equipment
does
cause
interference to radio or television reception, which
can be determined by turning the equipment off and
on, the user is encouraged to try to correct the inter-
ference by one or more of the following measures:
reorient the receiving antenna
relocate the computer with respect to the
receiver
move the computer away from the receiver
plug the computer into a different outlet so
ooo epee eee
aeseoower eo @
that computer and receiver are on different
branch circuits.
If necessary, the user should consult the dealer or an ,
experienced
radio/television
technician
for
additional
suggestions. The user may find the following booklet
prepared by the Federal Communications Commis-
sion
helpful:
