IMPOR TANT NOTICE
This manual has been provided for the use of authorized Yamaha Retailers and their service personnel. It has been assumed
that basic service procedures inherent to the industry, and more specifically Yamaha Products, are already known and understood by the users, and have therefore not been restated.
WARNING :
Failure to follow appropriate service and safety procedures when servicing this product may result in personal injury, destruction of expensive components and failure of the product to perform as specified. For
these reasons, we advise all Yamaha product owners that all service required should be performed by an
authorized Yamaha Retailer or the appointed service representative.
IMPORTANT :
This presentation or sale of this manual to any individual or firm does not constitute authorization certification, recognition of any applicable technical capabilities, or establish a principal-agent relationship of
any form.
The data provided is belived to be accurate and applicable to the unit(s) indicated on the cover. The research engineering, and
service departments of Yamaha are continually striving to improve Yamaha products. Modifications are, therefore, inevitable
and changes in specification are subject to change without notice or obligation to retrofit. Should any discrepancy appear to
exist, please contact the distributor’s Service Division.
WARNING :
Static discharges can destroy expensive components. Discharge any static electricity your body may have
accumulated by grounding yourself to the ground bus in the unit (heavy gauge black wires connect to
this bus.)
IMPORTANT :
Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power
to the unit.
LITHIUM BATTER Y HANDLING
This product uses a lithium battery for memory back-up.
WARNING :
Lithium batteries are dangerous because they can be exploded by improper handling. Observe the following precautions when handling or replacing lithium batteries.
Leave lithium battery replacement to qualified service personnel.
Always replace with batteries of the same type.
When installing on the PC board by soldering, solder using the connection terminals provided on the battery cells.
Never solder directly to the cells. Perform the soldering as quickly as possible.
Never reverse the battery polarities when installing.
Do not short the batteries.
Do not attempt to recharge these batteries.
Do not disasemble the batteries.
Never heat batteries or throw them into fire.
ADVARSEL!
Lithiumbatteri-Eksplosionsfare ved fejlagtig handtering. Udskiftning ma kun ske med batteri af samme fabrikat og type. lever det brugte
batteri tilbage til leverandren.
VARNING
Explosionsfara vid felaktigt batteribyte.
Anvand samma batterityp eller en ekvivalent typ som rekommenderas av apparattillverkaren.
Kassera anvant batteri enligt fabrikantens instruktion.
VAROITUS
Paristo voi rajahtaa, jos se on virheellisesti asennettu.
Vaihda paristo ainoastaan laitevalmistajan suosittelemaan tyyppiiin.
Havita kaytetty paristo valmistajan ohjeiden mukaisesti.
The following information complies with Dutch official Gazette 1995. 45; ESSENTIALS OF ORDER ON THE COLLECTION OF BATTERIES.
• Please refer to the diassembly procedure for the removal of Back-up Battery.
• Leest u voor het verwijderen van de backup batterij deze beschrijving.
WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (Where
applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly
other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHAT
SO EVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose
eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling
food.
WARNING
Components having special characteristics are marked
originally installed.

C. STARTING THE TEST PROGRAM AND CHECKING
While pressing the UTILITY, STORE and SYNC
switches, turn on the POWER switch. The TEST
program will then be started. At this time, check to make
sure that the model name “Ud.S” is displayed for about
2 seconds. The digit at the left end of the 7-segment
LED indicates the test No.
D. SELECTING THE TEST NUMBER
• Using the UP and DOWN switches, select the test
number and press the STORE switch to start testing.
E. OPERATION OF THE TEST PROGRAM AND CHECKING
0: LED check
(1) Using the UP and DOWN switches, select “0”.
(This step can be skipped if “0” is already selected.)
(2) Press the STORE switch.
• LED segments light up one after another starting
with “UP”. When “FUNCTION” is reached, “BANK”,
“3”, “2” and “1” light up followed by 7 segments in
the following order from the left end. After that, all
LED segments light up and go out.(Fig.1)

(3) Starting with the UP switch, press each switch whose
LED lights up one after another. After “FUNCTION”,
“BANK”, “3”, “2” and “1”, all LED segments should light
up and then go out.
• A number (0 to 20) is indicated at the right end of
the 7 segment LED.
• If “E” representing an error appears at the left end
of the LED, press the UTILITY switch for resetting.

• All LED segments light up and go out, and then the
checking proceeds to Battery check.
• If VR or EXP PEDAL is not set at its center position,
checking will result in an error and E. 0 will appear
at the left end of LED.
In such case, set it to the center position and press
UTILITY SW for resetting.
• To advance the VR No. (0-13) to be checked, press
UTILITY SW.

• If the check result is OK, all lights light up, go off and
the program proceed to the next step.
• If the check result is unsatisfactory, “E” appears at
the left end of the LED.
MIDI Check
• If the check result is OK, all LED segments light up
and go out. The checking function will proceed to the
next step.
• In case of an error, “E” appears at the left end of
the LED. “0” at the right end indicates transmission
and “1” indicates reception.

DSP Electric Characteristic
• An input signal will be output when the STORE
switch is pressed. “1” appears at the right end of
the LED. (Table.1)
• The sine waveform can be checked in all of the analog
circuit, A/D, DSP-6 and D/A where the signal has
passed.
• Initial setting : OUTPUT VR ••• MAX
: HIGH/LOW SW ••• OFF (LOW)
: The input impedance of the measuring
in strum ent should be 1MΩ or more.

CHEKING OF THE ROM VERSION
While pressing the DOWN and UTILITY switches, turn
on the POWER switch. The model name “Ud.S” is
displayed for about 2 seconds. As the version number
“1.00” (each * representing a number) appears after that,
check it. Then the mode will return to the normal mode.
ERROR MESSAGES
If an error occurs during operation, one of the following error message numbers will appear in the display.
Stop operation of the device and follow the proper solution described below.
E 1: MIDI Receive Buffer Full
CAUSE:
Too much MIDI data is being received at one time.
SOLUTION: Try reducing the amount of data being sent or, break the data into smaller blocks.
E 2: Communication Error.
CAUSE:
An abnormality is detected during MIDI communications.
SOLUTION: Check all connections, etc. and try again.
E 3: Bulk Receive Check Sum Error.
CAUSE:
The check sum does not match the received MIDI bulk data.
SOLUTION: Check all connections and data, and try again.
E 4: Bulk Receive Data Abnormality.
CAUSE:
An abnormality is detected in the received MIDI bulk data.
SOLUTION: Check all connections and data, and try again.
E 5: Backup Battery Error.
CAUSE:
Backup battery power is depleted.
SOLUTION: Continued use of the device will result in the loss of data.
