II. Points Of Caution

This instrument is constructed with very precise electronic parts.  Usage or storage under extreme temperature conditions, or strong shock must be avoided.  Under very low temperature conditions, the response speed may be slow or the instrument may fail to operate.  Also, under very high temperature conditions, the battery life will be shortened.  Do not store or place near heating systems, in direct sunlight, inside a hot car or on a window ledge.

The instrument is constructed to protect against dust and humidity but is not waterproof.  Do not use near splashing water or under high humidity conditions.

Do not attempt to take the instrument apart because the system and functions will be damaged.  Avoid throwing used batteries into fire.  If batteries go bad take them out at once and replace them to avoid damage to the instrument.

To clean the instrument, use a soft, dry cloth or slightly damp cloth with neutral detergent to wipe it off.  Never use thinner, benzene type solvents or alcohol for cleaning.

When using as a calculator be sure to check that the key depressed and the number indicated in the display are in agreement.

As a magnet is built into the speaker keep watches, credit cards, etc. clear of the unit.


III. Power Supply

The instrument has a two-way power system and may be operated using battery or AC power.

Battery Use:

Use 4 AA size dry batteries.

Battery life may vary depending on battery type and use conditions.
Music use (PLAY/REC mode) - 12 hours continuous.
Calculator use (CAL mode) - 4,000 hours continuous.
* Above battery life is based on type UM-3.

When the batteries are worn out the sounds and notes may become unstable or noise may be produced.  In this case the batteries should be replaced by new ones.

To replace batteries, slide open the battery compartment lid on the bottom of the instrument and insert new batteries making sure that the +/- poles are aligned.  Always replace all 4 batteries to insure longer life.

After replacing batteries, set the mode selector to "CAL" and press the [P] button on the bottom of the instrument with a pointed object.

CAUTION - To prevent corrosion or damage, remove the batteries when not using the instrument for long periods of time.


AC power can be used by connecting an optional AC adaptor.
* Use only the adaptor with the same voltage rating (100, 117, 220 or 240V) as your power supply to prevent component damage.

The battery power will be automatically disconnected when using the AC adaptor and will reduce battery consumption for better economy.


NOTE - When switching on the power with an AC adaptor in use, press the [P] button before playing the instrument with the mode selector at "CAL".

If you use the adaptor for long periods of time it may heat up but this is a normal condition.  The adaptor should be disconnected from the wall outlet when not in use.

The contents of the memory (accumulated total of memory calculation), stored memory or preset data of ADSR function will be cleared by replacing batteries.

Auto-Power-Off (A.P.O):

For power economy the unit provides auto-power-off (A.P.O) function.  If the unit is left with the mode selector turned on, the A.P.O. function automatically turns off the power in approximately 6 minutes.

Though the display disappears, the contents of the memory (accumulated total of the memory calculations or the preset data of the ADSR and/or the stored melody) are protected.  Power is resumed by pressing [RESET/AC] key or by turning off and on.

IX. ADSR Function
With this function you can create your own original sounds.

How the sound variations are formed:
Generally, a tone (character of a sound) is determined by pitch, loudness (strength) and timber (tone color).  Also in addition to the three elements mentioned above, there is another important factor for determination of a tone; so called "envelope" (the characteristic of the attack and decay of a sound).  In short, the change in loudness (amplitude) with the passage of time (duration).  For instance, a sound that slowly builds in loudness such as a violin.  Another example would be a sound that of a guitar where the loudness peaks momentarily when you pick the string and then reduces quickly.  These and many other sound wave variations are possible.  The illustration shows the envelope of a piano.  The graph shows the time (duration) horizontally and the amplitude vertically.  This is called an "envelope curve".  The ADSR function affects 5 elements (Attack, Decay, Sustain level, Sustain time, Release time) in determining the envelope curve and creates many sound wave variations.

ADSR is an acronym for the 5 elements
A: Attack time
D: Decay time
SL: Sustain level
ST: Sustain time
R: Release time
{diagram; ADSR}

How To Set And Use:
1. Let's form an 8 digit number to create a sound.
In the following paragraphs the numbers 0 to 9 will be used to determine the sound to be created.  8 numbers must be set in sequence.

a. Sound Waves - The following fundamental sound wave variations are available.
0 = Piano
1 = Fantasy
2 = Violin
3 = Flute
4 = Guitar 1
5 = Guitar 2
6 = English horn
7 = Electro-Sound 1
8 = Electro-Sound 2
9 = Electro-Sound 3

* For the items b through f on the right, the greater the number value (0-9) the greater the effect on the values illustrated on the graph.
b. Attack Time
c. Decay Time
d. Sustain Level
e. Sustain Time
f. Release Time

{diagram; ADSR}
b - A small value of b creates a fast rise time making a sharp sound.
c, d and e - A large value of c, d and e creates the sound of long duration such as that of a flute or organ.
Smaller numbers create sounds of shorter duration such as that of a guitar or koto.
f - A large value of f causes an echo effect even after you release the key.

* For the next two items a greater value causes a greater effect.  A "0" means no effect.
g - Vibrato - The pitch will vary at a high rate.
h - Tremolo - The volume will vary  at a high rate.

EXAMPLE: "61079130"
This series of numbers would create the sound wave variations of English horn.  The sound wave variations are shown on the graph.
{diagram; 61079130}

2. How To Store 8 Digits
The 8-digit number determined in Paragraph 1 (page 22) can be stored in the memory as follows:

1) Set the mode selector to CAL.
2) Set the sound selector to ADSR.
3) Press the [MC] key.
4) Press 8 numbers in sequence as shown in Paragraph 1.
CAUTION: If the first number is "0" that number will be ignored.
EXAMPLE: "02357806" = "2357806"; "00872850" = "872850"
5) Press the [M+] key.
6) Set the mode selector to PLAY or REC.
Now you can enjoy one key play, auto play or manual play with the ADSR sound.

Some examples of ADSR compositions:
Violin: 23099130
Piano: 00453200
Synthe-sounds: 70099924
Flute: 33099130
English horn: 61079130


X. Melody Demonstration

If you set the mode selector to PLAY or REC and then press the [MUSIC] key the "German Folk Song" will be played automatically.  The sounds and rhythms vary during the playing to cause a very pleasing demonstration.

A Standard tempo is set at (4).  You can change the tempo freely while playing by simply pressing the [[TEMPO]] keys.

The melody will be repeated 4 times and then will stop.  If you want to stop it during play simply press the [MUSIC] or [RESET] key.


XI. Connecting With Other Equipment
