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 distributor's 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 BATTERY 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

TEST PROGRAM
A. Connect each terminal as follows · INPUT Monaural input · OUT L/MONO Monaural output (RL47Kohm) · OUT R Monaural output (RL47Kohm) · HEAD PHONES Stereo output (323ohm each) · EXP. PEDAL Connect VR of B50K. Pin 1 of JK: MIN of VR, Pin 2 of JK: MAX of VR, Pin3 of JK: CENTER of VR · DIGITAL OUT Connect the DA converter. · MIDI IN, MIDI OUT Connect IN and OUT by using DIN 5P cable. · HIGH/LOW SW Used to select the input level. OFF: 0dB, ON: +10dB · AC IN Connect the AC adapter. · STAND-BY SW Power switch B. TEST PROGRAM 0: LED Check 1: SW Check 2: VR Check 3: Battery Check 4: MIDI Check 5: SRAM Check 6: DSP Check C. STARTING THE TEST PROGRAM While pressing the MANUAL, STORE and HALL switches, turn on the POWER switch. The TEST program will then be started. D. SELECTING THE TEST NUMBER Using the UP and DOWN switches, select the test number and press the STORE switch to confirm selection. E. TEST PROCEDURE 0: LED Check · Using the UP and DOWN switches, select "0" and then press the STORE switch. · LED segments light up one after another starting with "UP". When "SP.SIM" 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.

SW Check · Using the UP and DOWN switches, select "1" and then press the STORE switch. · Starting with the UP switch, press the switches whose LED lights up one after another. After "SP .SIM", "BANK", "3", "2" and "1", all LED segments should light up and then go out. · Numbers (0 to 20) are indicated at the right end of the 7 segment LED. · If "E" representing an error appears at the left end, press the UTILITY switch for resetting. VR Check · Using the UP and DOWN switches, select "2" and then press the STORE switch. · Execute checking with "AMP SELECT" and "GAIN" to "PRESENCE" in that order, next from "COMP" to "REVERB" and finally until "EXP. PEDAL" · Turn the control fully in the direction toward the left 7 segment LED which is turned on. If the test result is OK, the right 7 segment LED lights up. Then turn the control to that direction. If the test result is OK, proceed to the next VR. After completing this check, return the control to the center position. · If an error exists outside of the control being checked, "E" meaning an error appears at the left end. In such case, press the UTILITY switch for resetting. · At the end of all VR checks, all LED segments light up and go out. Battery Check · Using the UP and DOWN switches, select "3" and then press the STORE switch. · If the check result is OK, all LED segments light up and go out. · "E" appears in case of an error. MIDI Check · Using the UP and DOWN switches, select "4" and then press the STORE switch. · If the check result is OK, all LED segments light up and go out. Then checking advances to the next step. · In case of an error, "E" is indicated by LED. · The numeric figure at the right end of LEF represents, 0: transmission and 1: reception. SRAM Check · Using the UP and DOWN switches, select "5" and then press the STORE switch. · If the check result is OK, all LED segments light up and go out. · "0" and "1" at the right end represent IC2 and IC3 respectively.

HOW TO CONFRIM ROM VERSION Turn on the power while pressing "DOWN" and "MANUAL SW" switches, and the model name appears as dG.S for about 2 seconds and then the version number as *.** also for about 2 seconds. (Each * represents a numeric figure.) Read that number for confirmation. The normal mode will then be resumed.

ERROR MESSAGES
If an error occurs during operation, one of the following error message numbers will appear on the display.
E1: MIDI Receive Buffer Full
CAUSE: Too much MIDI data is being received by the DG amplifier at one time. SOLUTION: Try reducing the amount of data being sent or, break the data into smaller blocks.
E2: Communication Error.
CAUSE: An abnormality is detected during MIDI communications. SOLUTION: Check all connections, etc. and try again.
E3: 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.
E4: Bulk Receive Data Abnormality.
CAUSE: An abnormality is detected in the received MIDI bulk data. SOLUTION: Check all connections and data, and try again.
E5: Backup Battery Error.
CAUSE: Backup battery power is depleted. SOLUTION: Continued use of the device will result in the loss of data. Return the device to the music dealer where you purchased it or, have the battery replaced.
