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 håndtering. Udskiftning må kun ske med batteri af samme fabrikat og type. levér det brugte batteri tilbage
til leverandren.
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 tyyppiiin.
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.
リチウム電池の取り扱い
＜注意＞
リチウム電池を誤って交換すると爆発する危険があります。交換する場合は、サービスマニュアルで指定された部品を使用して
ください。
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: 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 and must be replaced with parts having specification equal to those
originally installed.

IMPORTANT NOTICE FOR THE UNITED KINGDOM
Connecting the Plug and Cord
WARNING:THIS APPARATUS MUST BE EARTHED
IMPORTANT. The wires in this mains lead are coloured in accordance
with the following code:
GREEN-AND-YELLOW : EARTH
BLUE : NEUTRAL
BROWN : LIVE
As the colours of the wires in the mains lead of this apparatus may not
correspond with the coloured markings identifying the terminals in your
plug proceed as follows:
The wire which is coloured GREEN-and-YELLOW must be connected to
the terminal in the plug which is marked by the letter E or by the safety
earth symbol or colored GREEN or GREEN-and-YELLOW.
The wire which is coloured BLUE must be connected to the terminal
which is marked with the letter N or coloured BLACK.
The wire which is coloured BROWN must be connected to the terminal
which is marked with the letter L or coloured RED.
Take care not to trap your fingers.
USER LEVEL SETTINGS
User Level settings allow you to restrict the parameters that can be operated by each user, or to change the settings of user-defined keys and
preference settings for each user.Settings for each user can be stored as a “user authentication key” on a USB storage device, allowing users
to be switched easily, simply by connecting this storage device to a USB connector.This is convenient in the following situations.
• Unintended or mistaken operation can be prevented.
• The range of functionality operable by an outside engineer (guest engineer) can be limited.
• In situations in which multiple operators alternate with each other, output settings etc.can be locked to prevent unintended operations.
• Preferences of each operator can easily be switched.
User settings may be stored by users.To service the device, get the USB storage device storing the "user authentic key" from the user.
BACKUP BATTERY
This device has a built-in backup battery. When you unplug the power cord from the AC outlet, the current scene data and
library data is retained.However, if the backup battery fully discharges, this data will be lost.When the backup battery is running
low, the LCD display indicates “Low Battery!” when you start up the system. (The Battery field indicates “LOW” or “NO” in the
SET UP screen.) In this case, immediately save the data to a USB storage device.
Be sure to
p
erform it
（作業中は指を挟まない様に注意してください。）
（ユーザーレベル設定）
ユーザーレベルを設定することにより、操作できるパラメーターをユーザーごとに制限したり、ユーザー定義キーやプリファレンス設定を
ユーザーごとに切り替えたりすることができます。ユーザーごとの設定は「ユーザー認証キー」としてUSB記憶装置にまとめて記憶してお
いて、これを USB端子に挿入することで簡単にユーザーを切り替えることができます。たとえば、以下のような場合に便利です。
･ 不用意な誤操作を防止できます。
･ 外部のエンジニア（ゲストエンジニア）が操作できる範囲を制限できます。
･ 複数のオペレーターが交代で操作する場合などに、出力設定をロックするなどして、誤操作を防止できます。
･ オペレーターごとに好みの設定に簡単に切り替えられます。
ユーザーがユーザーレベルを設定している場合がありますので、サービス実施時には、ユーザーから「ユーザー認証キー」を記憶してある
USB 記憶装置を借りてください。
（バックアップバッテリー）
この機器はバックアップバッテリーが内蔵されていますので、電源プラグがコンセントから外されても、電源を切ったとき
のカレントシーンデータやライブラリーデータは保持されます。ただし、バックアップバッテリーが消耗すると、カレント
シーンデータやライブラリーデータは消えてしまいます。バックアップバッテリーが消耗してくると、起動時にLow
Battery!と表示されます（SETUP画面の Battery欄でもバッテリーが消耗してくると LOWまたは NOと表示されます)。
その場合は、すぐにデータを USB記憶装置に保存してください。
