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.Components having special characteristics are marked and must be replaced with parts having specification equal to thoseoriginally installed.LITHIUM BATTERY HANDLINGThis 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 hndtering. Udskiftning m kun ske med batteri af samme fabrikat og type. levr det brugte batteri tilbage til leverandren.VARNING Explosionsfara vid felaktigt batteribyte.Anvnd samma batterityp eller en ekvivalent typ som rekommenderas av apparattillverkaren.Kassera anvnt batteri enligt fabrikantens instruktion.VAROITUS Paristo voi rjht, jos se on virheellisesti asennettu.Vaihda paristo ainoastaan laitevalmistajan suosittelemaan tyyppiiin.Hvit kytetty 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: This product contains chemicals known to the State of California to cause cancer, 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. 印部品、安全維持重要部品。交換場合、安全必指定部品使用。電池取扱注意 電池誤交換爆発危険。交換場合、指定部品使用。RadioFans.CN 收音机爱 好者资料库3QL5/QL1IMPORTANT NOTICE FOR THE UNITED KINGDOMConnecting the Plug and Cord WARNING: THIS APPARATUS MUST BE EARTHED IMPOR-TANT.

This device has a built-in backup battery that maintains internal clock data even when the device s power is switched off.However, the backup battery will eventually become depleted, and when that happens the internal clock data will be reset.Replace the backup battery before it becomes fully depleted.When the backup battery is running low, the LCD display indicates “Low Battery” when you start up the system. In this case, immediately save the data to a USB memory. The average life of the backup battery is approximately five years, depending on operating conditions.Be sure toperform it BACKUP BATTERY（）Functionality can be restricted for users other than the administrator at three levels of security: administrator, guest, and user. Passwords can be specifi ed for the administrator and for users to help prevent important settings from being changed accidentally.Information specifi c to each user (user level, system settings, and user-defi ned key/knob settings) can be stored on the unit or on a USB fl ash drive as a “user authentication key.” By loading your own user authentication key, you can instantly reconfi gure the unit for your own ideal operating environment.Since the password and user level may have been set up by the user, borrow a USB memory device where the “password” and “user authentication key” are stored from the user during service implementation.管理者、一般 3 段階分、管理者以外操作機能制限。管理者一般設定、不用意重要設定変防。、 認証呼各種情報（、環境設定、USER DEFINED 設定内容）本体 USB 保存。自分認証読込、使勝手含操作環境再現。設定場合、 実施時、 認証記憶 USB 記憶装置借。 USER LEVEL SETTINGS（設定）This product contains a battery that contains perchlorate material.Perchlorate Material special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate.* This applies only to products distributed by YAMAHA CORPORATION OF AMERICA.
