Description; Precautions - Yamaha KX88 Authorized Product Manual

DESCRIPTION

The Yamaha KX88 is an 88 key, weighted action MIDI
keyboard and control center for all MIDI equipped instru-
ments and devices. It is the first completely programmable
and assignable MIDI keyboard. Each of the controllers
(pitch and modulation wheels, after touch, breath control-
ler, 2 foot controllers, 2 foot switches, 4 front panel sliders
and 7 front panel buttons) may be programmed to send any
type of MIDI information.
Also, the keyboard may be used in one of three modes
Single: All key on/off signals are sent on one MIDI channel.
Dual: All key on/off signals are sent simultaneously on
two MIDI channels.
Split: The keyboard may be split at any selected point,
and upper and lower sections sent on different MIDI
channels.

PRECAUTIONS

LOCATION
Avoid placing the KX88 in direct sunlight or close to a
source of heat. Also, avoid locations in which the instru-
ment is likely to be subjected to vibration, excessive dust,
cold or moisture.
HANDLING
Avoid applying excessive force to the slide knobs, dropping
or rough handling. While the internal circuitry is of reliable,
integrated circuit design, the KX88 is nonetheless a fine
instrument that should be treated with care.
POWER CORD
Always grip the plug directly when removing it from
an AC receptacle. Removing the plug from the AC receptacle
by pulling the cord can result in damage to the cord, and
possibly a short circuit. It is also a good idea to disconnect
the KX88 from the AC receptacle if you don't plan to use
the instrument for an extended period of time.
The keyboard may be transposed up or down in half-
steps, to a maximum of ±2 octaves. In split mode, the
upper and lower sections may be transposed independently.
All settings (keyboard mode, MIDI channel, transpose and
controller assignment) may be stored in one of 16 memory
banks, and recalled by any specified controller.
CLEANlNG
Use only a mild detergent on a cloth, and dry with a soft
cloth. Never use solvents (such as benzine or thinner)
since they can melt or discolor the instrument.
ELECTRICAL STORMS (LIGHTNING)
Computer circuitry, including that in the KX88, is sensitive
to voltage spikes. For this reason, the DX7 should be
turned off and unplugged from the AC receptacle in the
event of an electrical storm. This precaution will avoid the
chance that a high voltage spike caused by lightning will
damage the instrument.
ELECTRO-MAGNETIC FIELDS
Computer circuitry is also sensitive to electromagnetic
radiation. Television sets, as well as radio receivers, trans-
mitters and transceivers, and wireless microphone or
intercom systems are all potential sources of such radiation,
and should be.
