SAFETY NOTICE
CAUTION!
Danger of explosion if battery is incorrectly replaced. Replace
only with the same or equivalent type.
DENMARK:
ADVARSE!
Lithiumbatteri. Eksplosionsfare ved fejlagtig handtering.
Udskiftning ma kun ske med batteri af samme fabrikat og type.
Lever det brugte batteri tilbage tili leverandoren.
FINLAND:
VAROITUS
Paristo voiäjähtää, jos se on virheellisesti asennettu. Vaihda
paristo ainoastaan valmistajan suosittelemaan tyyppiin. Hävitä
käytetty paristo valmistajan ohjeiden mukaisesti.
SWEDEN:
VARNING
Felaktigt batteribyte kan medf fara för explosion. Använd därför endast samma typ eller likvärdig typ enligt apparattillverkarens rekommendation.

IMPORTANT OPERATION
Full Initialization
Use this procedure to return all keyboard settings to what they were when you purchased it. Note that this
procedure clears all data from memory.
• While holding down the ENTER button, turn on keyboard power.
R e s e t?
• Press YES to initialize the keyboard or NO to turn on power without changing any settings.
Parameter Initialization
Use this procedure to return all keyboard settings to what they were when you purchased it. Note that this
procedure does not affect user tones, user rhythms, registration memory contents, and display contrast
settings.
• While keyboard power is on, press the [+], [–], and ENTER buttons at the same time.
Adjusting Display Contrast
• Display contrast can be adjust to one of 100 levels for easy viewing.
• Adjusting display contrast helps to make figures easier to read from any viewing angle.
• Within five seconds after pressing the CONTRAST button, press [+] to increase the contrast value (making the display darker) or [–] to decrease it (making the display lighter).
• After you release CONTRAST, the message “Contrast” remains on the display for a few moments, during
which you can change the contrast setting further using [+] and [–] or by inputting a contrast value with the
number keys.
The contrast can be set to a value from 0 to 99. The initial default setting is 50.
GM (General MIDI):
General MIDI standardizes MIDI data to play music with same nuance between different MIDI instruments.
Among GM conformed MIDI instruments, or commercially available musical data, music can be played with
similar tones.
SMF (Standard MIDI File):
SMF is a standard file format for MIDI instruments and computer music software. SMF formatted data can
be played and transported easily among SMF complied instruments or musical data of different manufacturers.

Initial reset
When batteries are set or an AC adapter is connected, the reset IC provides a low pulse to the CPU.
When the power switch is pressed, the CPU receives a low pulse of POWER signal. The CPU first raises
APO signal to +5 V to generate DVDD voltage, then raises RESET signal to +5 V. During this period the
DSP and the key controller LSI initialize their internal circuits.

POWER SUPPLY CIRCUIT
The power supply circuit provides various voltages as shown below.
The voltage VDD (+5 V) is provided as long as batteries or AC adaptor is set.
Other voltages are controlled by APO (Auto Power Off) signal from CPU.

DIGITAL SIGNAL PROCESSOR (LSI4: HG51A115A01FD)
Upon receipt of note numbers and their velocities, the DSP (Digital Signal Processor) reads sound and
velocity data from the sound source ROM in accordance with the selected tone; the DSP can read rhythm
data simultaneously when a rythm pattern is selected. Then it provides 16-bit serial signals containing data
of the melody, chord, bass, and percussion to the DAC. The DSP also adds the selected effect to the sound
data using a 256k-bit RAM.
The following table shows the pin functions of the DSP.

■ Bender check
1. While pitch bender is left untouched, press “–” button.
2. Display indicates “Bender”.
3. If the bender’s center point is adjusted correctly, the instrument emits verification sound. If the center
point is improper, an error alarm sounds and display indicates “Bend ER” and the instrument exits
from the diagnostic program.
4. Rotate the bender all the way to the upper position.
When the program detects upper most position, it emits verification sound. If wrong direction (toward
lower position ) of bender rotation is detected, the instrument exits from the diagnostic program after
emitting an alarm sound and displaying “Bend ER”.
5. Reset the bender on the center position.
A verification tone sounds.
6. Rotate the bender all the way to the lower position.
When the program detects lower most position, it emits verification sound.
If wrong direction (toward upper position) is detected, the instrument exits from the diagnostic program after emitting an alarm sound and displaying “Bender ER”.
7. Reset the bender on the center position.
The instrument exits from diagnostic program after emitting a verification sound and displaying “Bend
OK”. (During and after the check, display indicates bender values until another button is pressed.)
■ AC adaptor detection check.
1. Press “+” button.
2. When the instrument detects that an AC adaptor is plugged in, it indicates “Jack OK” on the display.
If it judges that no AC adaptor is inserted (powered by batteries), it indicates “Jack ER” on the display.
■ Keyboard, Sustain pedal, and Modulation switch check
1. Press “1” button.
2. Display indicates “TouchSus”.
In accordance with key, sustain pedal, or module switch depressions, display indicates velocity value
(hexadecimal values 01 to 7F), “SUS”, or “Mod”.
■ ROM check
1. Press “2” button.
2. The diagnostic program counts check sums of 8Mbit and 16Mbit ROMs.
3. In accordance with ROMs functions, display indicates;
“ROM OKOK” -------------- Both ROMs function normally
“ROM OKER” -------------- 8Mbit ROM OK, 16Mbit ROM NG
“ROM EROK” -------------- 8Mbit ROM NG, 16Mbit ROM OK
“ROM ERER” -------------- Both ROMs are NG

■ RAM check
1. Press “3” button.
2. The program executes write/read test in all the RAM area.
3. When the RAM is proper, display indicates “RAM OK”.
If the RAM malfunctions, “RAM NG” is shown on the display.
4. When the RAM check is executed, other tests become unavailable.
5. Pressing any key performs “Bender reset” transaction described below.
■ Small sound output
1. Press “4” button.
2. The instrument emits a sound in small volume and indicates “MIN” on the display.
■ Medium sound output
1. Press “5” button.
2. The instrument emits a medium volume sound and indicates “MID” on the display.
■ Large sound output
1. Press “6” button.
2. The instrument emits a large volume sound and indicates “MAX” on the display.
■ Large sound left channel output
1. Press “7” button.
2. The instrument emits a large volume sound from the left speaker and indicates “L” on the display.
■ Large sound right channel output
1. Press “8” button.
2. The instrument emits a large volume sound from the right channel and indicates “R” on the display.
■ MIDI IN/OUT test
1. Connect MIDI IN and MIDI OUT terminals with a MIDI cable.
2. Press “9” button.
3. When the MIDI circuit is normal, display indicates “MIDI OK” whereas “MIDI ER” will be shown if the
MIDI circuit is abnormal.

■ Bender reset
Sets bender’s center point in initial value.
1. While pressing down “ENTER” and “ACCOMP CHORD MODE” buttons, turn the power on.
2. Display shows “BndReset” indicating that pitch bender’s center point is initialized.
3. Perform the “System reset” described below.
■ System reset
1. While pressing down “ENTER” button, turn power on.
2. Display indicates “Reset?”.
3. Pressing “+” button initializes the instrument.
Pressing “–” button invalidates system reset.
4. The instrument turns on automatically.
■ Touch off max
1. While pressing down “RHYTHM” and “ACCOMP CHORD MODE” buttons, turn the power on.
2. Display indicates “TouchMax”.
3. The instrument is set in touch off max mode.
