- 3 - general adjustments specific informations service safety precautions ? the caution items shown here describe major safety issues and should always be observed. ? the meanings of the various indications are as follows. warning caution indicates a hypothetical situation in which service personnel and nearby third parties, or even end users due to a product defect after the service operation is completed, could possibly be in danger of injury or even death in the event of operational error. indicates a hypothetical situation in which service personnel and nearby third parties, or even end users after the service operation is completed, could possibly be in danger of injury, or where there could be physical damage in the event of operational error. * physical damage means major damage to a home, furnishings and other possessions. examples of marks shock hazard prohibit disassem- bling unpulug the " indicates caution (including danger and warning). the actual meaning of this caution is indicated inside the " or nearby illustrations or text. the example shown to the left indicates the danger of "electrical shock". the indicates a forbidden action. the actual meaning of this caution is indicated inside the or nearby illustrations or text. the example shown to the left indicates that disassembly is forbidden. the - indicates a forced action (an action that must be performed). the actual meaning of this forced action is indicated by - or nearby illustrations or text. the example shown to the left indicates that the power plug must be disconnected.
- 4 - warning keep children away unpulug shock hazard use specified parts caution for wiring caution for assembling / wiring check insulation resistance prohibit remodeling ? always advise users to keep children away. there is danger of injury to children from tools, disassembled products, etc. ? 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 pos- sible 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 character- istics. 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 recon- nect the wiring, in accordance with the original scheme. do not allow internal wiring to be pinched by cabinets, panels, etc. any error in reassembly or wiring can result in electrical leakage, flame, etc., and may be 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 insulation resistance is 1m 1 or more. the set will require inspection and repair if the insulation resistance is below this value. ? never remodel the product in any way. remodeling can result in improper operation, malfunction, or electrical leakage and flame, which may be hazardous
