SAFETY INSTRUCTIONS

WARNING: BEFORE SERVICING THIS CHASSIS, READ THE ＂SAFETY PRECAUTION＂

AND ＂PRODUCT SAFETY NOTICE＂INSTRUCTIONS BELOW.

SAFETY PRECAUTION

WARNING: SERVICE SHOULD NOT BE ATTEMPTED BY ANYONE UNFAMILIAR WITH THE NECESSARY

PRECAUTIONS ON THIS RECEIVER. THE FOLLOWING ARE THE NECESSARY PRECAUTIONS TO BE

OBSERVED BEFORE SERVICING THIS CHASSIS.

・An isolation transformer should be connected in the power line between the receiver and the AC line before any service

is performed on the receiver.

・When replacing a chassis in the cabinet, always be certain that all the protective devices are put back in place, such as;

nonmetallic control knobs, insulating covers, shields, isolation resistor-capacitor network etc.

・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 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

include 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 pars, 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 reassembly or wiring

can result in electrical leakage, flame, etc.,and may be hazardous.

・Never remodel the product in any way. Remodeling can result in improper operation, malfunction, or electrical leakage and

flame, which may be hazardous.
