Important
Precautions
u Please be careful of extreme
temperatures, moisture and
direct sunlight.
Please avoid using or storing your
DG-20 in places subject to direct
sunlight, excessively damp places
or near air conditioning and
heating appliances where
temperatures and moisture tend to
be extreme. Also, do not leave this
unit in an automobile with the
windows closed during hot
summer months.
E Please do not drop this
instrument or subject it to
strong shocks.
Subjecting this precision
instrument to strong shocks may
cause malfunctions or damage the
neck, so please use extreme care
in handling.
E Make sure no foreign matter
gets inside of this unit.
Please take care that no foreign
objects, especially metal objects
such as hair pins, sewing needles
or coins get into the unit. Any
metal objects or liquids entering
the unit may cause malfunctioning
as well as an electric shock
hazard.
= Customizing may cause
malfunction and accidents.
The DG-20 uses many high-
precision electronic components.
Converting it in any manner or
needlessly touching internal parts
may cause malfunction and
accidents and should therefore be
avoided under all circumstances.
® Do not use thinner or similar
chemicals when cleaning this
unit.
To clean the DG-20, wipe the
exterior surface with a soft cloth
dampened with a neutral
detergent solution which has been
wrung out completely. Never use
paint thinner, benzene or other
solvents.

Making Music
On the DG-20
1. When a string is played, the
string's vibration is sensed by a
built-in sensor and the selected
tone is output through the built-in
speaker.
2. The digital guitar features
switches which are actually built-in
to the fingerboard, behind each
fret. If your finger(s) is not properly
centered over the strings you
depress, neighboring strings may
sound (even though you haven't
depressed neighboring strings), as
the switches may be activated.
No sound is output if strings
are played too softly.

Note:
There are two different basic types
of preset sounds built-in to the
DG-20—sounds which decay, such
as the acoustic guitar tone, and
sounds which are sustained, such
as the jazz organ tone. Sustained
sounds may be cut off by using
the mute key, or by releasing the
fretboard (which turns OFF the
built-in sensor switch).

inserting and
Replacing Batteries
Remove the battery compartment
cover and insert batteries, taking
care that polarity is correct. When
replacing batteries, be sure to
replace all six to ensure longer
battery life.
Turn power OFF before
replacing batteries.
= Battery life of high-performance
SUM-1 dry cells is approximately
18 hours. Weakened batteries will
Cause the power indicator to lose
Its brightness and result in lower
volume, poor tonal quality and
eventually misoperation of
unctions. If such symptoms occur,
replace all six batteries with new
Ones as soon as possible.

Connection of an AC adaptor
(AD-5, optional) allows the unit to
be powered by standard
household current.
Use only an adaptor with the same
voitage rating as your local power
supply.
Connection of a car adaptor (CA-5,
optional) allows the unit to be pow-
ered through a vehicle’s cigarette
lighter socket.
® Always ensure that the power of
the unit is OFF when connecting
or disconnecting adaptors.
B Remove batteries from the
battery compartment when the
unit is not used for extended
periods. Battery leakage can
damage electrical components.
E Only use specified CASIO AC or
Car adaptors to prevent damage to
the unit.
HN Adaptors normaliy become
warm when connected to the
power source. This is not cause
for worry, but adaptors should be
disconnected whenever the unit is
not used for extended periods.
Auto Power OH
Function
An automatic power cut-off
function activates approximately 6
minutes after the last operation of
the unit. Power supply can be
restored by switching the power of
the unit OFF and then ON again.

About MIDI
1. Performing Using MIDI
Remote and Ensemble
Performance
By connecting the DG-20 to
another MIDI instrument, 6-note
polyphonic note messages can be
sent to the other instrument.
Through this the DG-20 can be
used to “control” or play the
other instrument, for example a
keyboard instrument.
Sequential
Performance with
Rhythm Machines
and Sequencers
The DG-20 can be used to
start/stop the connected drum
machines or sequencers, for
precision rhythm track or
sequence control.
Control Up To 6
Different Sound
Sources
(MIDI Mode 4)
By connecting the DG-20 to a CZ-1,
CZ-5000 or other keyboard with a
multi-receive mode, or by connect-
ing the DG-20 to up to 6 different
keyboards, a maximum of 6 differ-
ent voices can be controlled by the
DG-20—with a different voice
assigned to each string.
I. Transmitted MIDI
Data
The DG-20 Can
Transmit The Following
MIDI Data
1) Pitch, ON/OFF
2) Start/stop
3) Timing clock
4) Program change (voice number,
rhythm number)
5) Portamento (When changed
from MODE | to MODE II,
PORTAMENTO ON is sent auto-
maticaly to Channels 1 through 6.
When you switch from MODE | to
MODE Il, PORTAMENTO OFF is
sent on the Basic Channel only).
