1. Warning
To prevent the risk of fire, smoke, orelectrical shock and toensure safe operation, please be
sure tofollowthe safetyguidelines below.
1. Atplaces where special caution isrequired, the necessarysafety
precautions are clearlylabeled or printed, for example, on the
cabinet, or on the part concerned. Please follow these safety
precautions, and also those listed inthe Owner'sManual.
2. Parts which have a;mark inthe circuitdiagram or inthe parts
4

list are essential for safety. When replacing these parts, be sure to
use onlythe specified parts.
3. Use the specified types for internal wiring (double-insulated
wiring, etc.).
4. When replacing parts on the AC primaryside (power transformer,
electricswitch, electrical cord, noise-prevention condenser, etc.),
wind the lead wire and secure itbysoldering.
5. Donot let the wiring come into contact with heat-emitting devices
(fuse resistor, radiator plate, etc.).
6. When replacing the wiring, make sure that itisnot incontact with
the unfinished or rough edge of apart.
7. When replacing the power cord (except for the plug-intype), tug it
from various directions to confirm that itdoes not slipout of
place.
8. Spacing
Ifsoldering was done on the AC primarycircuit, confirm that the
interval between the soldered terminalsor between the terminal
and surrounding metallicparts isat least the minimum required
(between the primarycircuitand the chassis: atleast6.5mm;
between primarycircuitterminals: at least 4.0mm; between
primarycircuitterminalsand secondarycircuitterminals: at least
6.5mm.).
2. Safety Precaution
2.1. SafetyPrecaution
1. Before servicing, unplug the power cord to prevent an electric
shock.
2. When replacing parts, use onlythe manufacturer’srecommended
components for safety.
3. Check the condition of the power cord. Replace ifwear or damage
isevident.
4. After servicing, be sure to restore the lead dress, insulation
barriers, insulation papers, shields, etc.
5. Before returning the serviced equipment to the customer, be sure
5

to make the following insulation resistance test to prevent the
customer from being exposed to ashock hazard.
2.2. Insulation Resistance Test
1. Unplug the power cord and short the prongs of the plug with a
jumper wire.
2. Turn on the power switch.
3. Measure the resistance value with an ohmmeter between the
jumpered AC plug and each exposed metal cabinet part, such as
screw heads, connectors, control shafts, handlebrackets, etc.
Measurements shouldrange from 4MOhm to infinityfor
allexposedparts.(refer to Fig.1 )

the part isoperating properly, “OK”isshown, excluding the
Expression Pedal. (refer to Fig.17 )
-When akeyboard keyispressed, the corresponding pitch and
velocityaftertouch isdisplayed (onlyas long as the keyis
depressed).
-The respective statuses for other input action parts are displayed.
(Analog parts are shownas numerical values from 0to 255, and
switches are shownas ONor OFF.)
-Ifthe displayfailsto change when the part isoperated, or ifthe
change isabnormal, itmayindicate adefective part.
8.8. MIDI IN/OUTtest Fig.18

1. Generate afull amplitude sine wave inthe pitch of each key. (No
touch, fixed stereo center).
Ifno sound isgenerated or ifthe sound isdistorted, the sound
generator ROMcorresponding to the keyposition isdefective.
2. For confirming the output pathwayfrom the sound generator.
(Fixed scale, no touch)
The Lch and Rch sound outputs are confirmed separately.
3. Generate afull amplitude sine wave inthe pitch of each key+2
octaves. (Notouch, fixed stereo center)
Bygenerating asound frequencyoutside the normal keyboard
zone, you can confirm whether or not there isan abnormalityin
the sound output frequencyzone.
4. Generates afull amplitude sine wave inthe pitch of each key-2
octaves. (Notouch, fixed stereo center)
Bygenerating asound frequencyoutside the normal keyboard
zone, you can confirm whether or not there isan abnormalityin
the sound output frequencyzone.
5. Generate asine wave inthe pitch of each keywith touch.
You can confirm ifthe volume changes depending on the touch.
6. Generate afull amplitude sine wave inthe pitch of each keyat a-
16 dBvolume. (Notouch, fixed stereo center)
You can confirm the same sound output as in1, at alower volume.
9. Precautions before Servicing
9.1. Precautions for measuring of the output waveforms
1. The waveform was measured with a“National Digital Storage
19

Oscilloscope VP-5730A”. Therefore the waveforms of musical
tone signalsshownmaydiffer somewhat due to the difference in
the timing of triggering.
2. Since the 1/10 test probe isused, the indicated voltage value on
the bottom part of each waveform illustration is1/10 of the actual
value (e.g. 0.2V/cm shouldbe 2.0V/cm).
3. To measure the waveforms, first set thisunitto the service
diagnosticmode (refer to “ WAVE ROM test ”). The WAVE ROM
output will then be output as asine wave to facilitate
theservicingcheck.
9.2. Important safetynotice
-Components identified byamark have special characteristics
impotant for safety.
-When replacing anyof these components, use onlymanufacture’s
specified parts.
9.3. SymbolicMarks
The symbolic marks forresistors and capacitors whichusedinthis circuits are classifiedas
following Table-1 and Table-2 .
9.3.1. RESISTORS
-Resistors without symbolicmark are FIXEDCARBONFILM
RESISTORS(ERD-type).
-All resistors are 1/4WATT, ±5%TOLERANCEunless otherwise
designated inschematicdiagrams.
