WARNINGS Take care to heed the following warnings: KEEP CHILDREN AWAY Always advise users to keep children away. There is danger of injury to children from tools, disassembled products, etc. 2 Unplug 4 UNPLUG H SHOCK HAZARD USE SPECIFIED PARTS CAUTION FOR WIRING Always disconnect the power plug before starting work whenever power is not required. Failure to disconnect the power plug before starting work can result in electrical shock. Depending on the model, use an insulation transformer or wear gloves when servicing with the power on, and disconnect the power plug to avoid electrical shock when replacing parts. In some cases, alternating current is also impressed in the chassis, so electrical shock is possible if the chassis is contacted with the power on. Always use the replacement parts specified for the particular model when making repairs. The parts used in products have the necessary safety characteristics such as inflammability, voltage resistance, etc.; therefore, use only replacement parts that have these same characteristics. Use only the specified parts when the mark is included in a circuit diagram or parts list. Parts mounting and routing of the wiring should be the same as that used originally. For safety purposes, insulating materials such as tubing or tape is sometimes used and printed circuit boards are sometimes mounted floating. Also make sure that wiring is routed and clamped to avoid parts that generate heat and which use high voltage. Always follow the original scheme. After a repair has been completed, reassemble all disassembled parts, and route and reconnect the wiring, in accordance with the original scheme. Do not allow internal wiring to be pinched by cabinets, panels, etc. Any error in CAUTION FOR reassembly or wiring can result in electrical leakage, flame, etc., and may be ASSEMBLY/WIRING hazardous. After completing the work, disconnect the power plug from the outlet, remove the antenna, turn on the power switch. Then, use a 500V insulation resistance meter to check the insulation resistance of the antenna terminal, other metallic parts and between the prongs of the power plug to make sure that the insula- CHECK INSULA- tion resistance is 1M Ω or more. The set will require inspection and repair if the TION RESISTANCE insulation resistance is below this value. Never remodel the product in any way. Remodelling can result in improper operation, malfunction, or electrical leakage and flame, PROHIBIT REMOD- which may be hazardous ELLING 3
