SAFETY INSTRUCTION
WARNING: BEFORE SERVICING THIS CHASSIS, READ THE "SAFETY
PRECAUTION" AND "PRODUCT SAFETY NOTICE" INSTRUCTIONS
BELOW.
Safety Precaution
WARNING: SERVICING 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.
1. 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.
2. Always disconnect the power plug before any disassembling of the product. It may
result in electrical shock.
3. 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.
4. Always keep tools, components of the product, etc away from the children, These
items may cause injury to children.
5. Depending on the model, use an isolation transformer or wear suitable 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.
file:///D|/111/32AV615DG-01/html/!!_index.html[7/27/2012 9:33:04 AM]
6. Always use the replacement parts specified for the particular model when making
repairs. The parts used in products require special 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
indicated in the circuit diagram or parts list.
