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.
IMPORTANT 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.
WARNING
Components having special characteristics are marked and must be replaced with parts having specification equal to those
originally installed.
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 disassemble the batteries.
Never heat batteries or throw them into fire.
ADVARSEL!
Lithiumbatteri-Eksplosionsfare ved fejlagtig håndtering. Udskiftning må kun ske med batteri af samme fabrikat og type. Levér det
brugte batteri tilbage til leverandøren.
VARNING
Explosionsfara vid felaktigt batteribyte.
Använd samma batterityp eller en ekvivalent typ som rekommenderas av apparattillverkaren.
Kassera använt batteri enligt fabrikantens instruktion.
VAROITUS
Paristo voi räjähtää, jos se on virheellisesti asennettu.
Vaihda paristo ainoastaan laitevalmistajan suosittelemaan tyyppiin.
Hävitä käytetty 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.

INSTALLING I/O CARDS
SREV1
16
This section explains how to install mini YGDAI cards in the SREV1.
1. Turn off the SREV1.
2. Undo the two fixing screws and remove the slot cover, as shown below.
Keep the cover and fixing screws in a safe place for future use.
3. Insert the card between the guide rails and slide it all the way into the slot, as shown below. You may have to
push firmly to plug the card into the SREV1 connector.
4. Secure the card using the attached thumbscrews. Do not leave the thumb-screws loose, as the card will not be
grounded correctly.

DB-SREV1 INSTALLATION
* Before installing the DB-SREV1 (CNV) circuit board,
turn off the SREV1 and disconnect the power cord.
1. Top Cover Removal
Remove the fourteen (14) screws marked [850]. The top
cover can then removed. (Fig. 1)
2. CNV Circuit Board Removal
Remove the two (2) screws marked [350] and the two (2)
screws marked [360]. The CNV circuit board can then be
removed. (Fig. 2, 3)
3. Cables Connection
Connect the two supplied cables to the CPU circuit board
(CN118, CN119) so that the printed side appears as shown
as in Figure 4, and then close the securing clips on each
side of the connectors.
* The two supplied cables are identical.

6. Re-attach the SREV1 Top Cover
Replace the fourteen (14) fixing screws marked [850].
The top cover can then be Replaced. (Fig. 1)
7. Checking that the DB-SREV1 (CNV) Circuit
Board is Working Correctly
If the DB-SREV1 (CNV) circuit board is working correctly,
when the SREV1 is turned on the two rows of INPUT and
OUTPUT front panel indicators light up alternately in a
streaming pattern from left to right. If the indicators do not
light up like this, the DB-SREV1 (CNV) circuit board is not
working correctly, in which case you should check that it's
installed in accordance with these instructions.
8. Execute Test Program
Execute test program No. 5 in Section 5-2 and check if
operation is normal. (Refer to page 42.)

4. CNV Circuit Board Installation
Reinstall the previously removed CNV circuit board,
remembering to replace the two (2) internal fixing screws
marked [360] and two (2) external fixing screws marked
[350]. (Fig. 2, 3)
Reconnect the two cable connectors and the power supply
connector. (Table 1)
5.
DB-SREV1 (CNV) Circuit Board Installation
5-1 Cut and remove the cable fastener holding the power supply
cable intended for the DB-SREV1(CNV) circuit board.
5-2 Install the DB-SREV1 (CNV) circuit board above the
existing CNV circuit board, secure it by using two (2)
internal fixing screws marked [B] and two (2) external
fixing screws marked [A]. (Fig. 2, 3)
5-3 Connect the two cable connectors and the power supply
connector, as shown in Figure 5. (Table 1)
