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. 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.

IMPORTANT :

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 distributors Service Division.

WARNING : IMPORTANT :

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.) 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. and must be replaced with parts having specification equal to those

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.
