 WARNING
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 : 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.
Components having special characteristics are marked  and must be replaced with parts having specification equal to thoseoriginally 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 connectio\
n 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 Batt\
ery.

IMPORTANT NOTICE FOR THE UNITED KINGDOM
Connecting the Plug and Cord
WARNING:THIS APPARATUS MUST BE EARTHEDIMPORTANT. The wires in this mains lead are coloured in accordancewith the following code: GREEN-AND-YELLOW : EARTHBLUE: NEUTRALBROWN: LIVEAs the colours of the wires in the mains lead of this apparatus may notcorrespond with the coloured markings identifying the terminals in your \
plug proceed as follows:The wire which is coloured GREEN-and-YELLOW must be connected tothe terminal in the plug which is marked by the letter E or by the safet\
yearth symbol or or colored GREEN or GREEN-and-YELLOW.The wire which is coloured BLUE must be connected to the terminalwhich is marked with the letter N or coloured BLACK.The wire which is coloured BROWN must be connected to the terminalwhich is marked with the letter L or coloured RED.     

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 starting up the system. (the Battery field also indicates “LOW” or “NO” in the MISC SETUP screen.) In this case, immediately save the data to a USB memory.Be sure toperform it
 BACKUP BATTERY（バックアップバッテリー）
User  Level  settings  allow  you  to  restrict  the  parameters  that  be  operated  by  each  user,  or  tochange  the  settings  of  the  custom  fader  layer, user-defined  keys,  and  preference  settings  foreach  user.  Settings  for  each  user  can  be  stored  as  a  “user  authentication  key”  on  USB memory,allowing  users  to  be  switched  easily,  simply  by  connecting  the  memory  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 engin\
eer) 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 authe\
ntic key" from the user. 
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、カスタムフェーダーレイヤーや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U S B メモリーにまとめて記憶しておいて、これを U S B 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。
 USER LEVEL SETTINGS（ユーザーレベル設定）
This  product  contains  a  battery  that  contains  perchlorate 
material.
