                                                                                             Caution

 1.   Caution


                                               CAUTION
                                           RISK OF ELECTRIC SHOCK
                                                 DO NOT OPEN




                  The lightning flash with arrowhead symbol, within an equilateral triangle, is
                  intended to alert the user to the presence of uninsulated "dangerous voltage"
                  within the product's enclosure that may be of sufficient magnitude to constitute a
                  risk of electric shock to persons.


                  The exclamation point within an equilateral triangle is intended to alert the user to
                  the presence of important operating and maintenance (servicing) instructions in
                  the literature accompanying the appliance.


       Precautions During Servicing
           1. In addition to safety, other parts and assemblies are specified for conformance
              with such regulations as those applying to spurious radiation. These must also be
              replaced only with specified replacements.
              Examples: RF converters, tuner units, antenna selection switches, RF cables,
              noise-blocking capacitors, noise-blocking filters, etc.

           2. Use specified internal Wiring. Note especially:
              1) Wires covered with PVC tubing
              2) Double insulated wires
              3) High voltage leads

           3. Use specified insulating materials for hazardous live parts. Note especially:
              1) Insulating Tape
              2) PVC tubing
              3) Spacers (insulating barriers)
              4) Insulating sheets for transistors
              5) Plastic screws for fixing micro switches

           4. When replacing AC primary side components(transformers, power cords, noise
              blockin capacitors, etc.), wrap ends of wires securely about the terminals before
              soldering.

                                                                                            Caution

           5. Make sure that wires do not contact heat generating parts (heat sinks, oxide metal film
              resistors, fusible resistors, etc.)
           6. Check if replaced wires do not contact sharply edged or pointed parts.
           7. Make sure that foreign objects (screws, solder droplets, etc.) do not remain inside the
              set.

           MAKE YOUR CONTRIBUTION TO PROTECT THE ENVIRONMENT
           Used batteries with the ISO symbol




           for recycling as well as small accumulators(rechargeable batteries), mini-batteries
           (cells) and starter batteries should not be thrown into the garbage can.
           Please leave them at an appropriate depot.

           WARNING:
           Before servicing this TV receiver, read the SAFETY INSTRUCTION and PRODUCT
           AFETY NOTICE.

           SAFETY INSTRUCTION
           The service should not be attempted by anyone unfamiliar with the necessary
           instructions on this apparatus. The following are the necessary instructions to be
           observed before servicing.
           1. An isolation transformer should be connected in the power line between the receiver
              and the AC line when a service is performed on the primary of the converter
              transformer of the set.
           2. Comply with all caution and safety related provided on the back of the cabinet, inside
              the cabinet, on the chassis or LCD panel.
           3. When replacing a MAIN PCB in the cabinet,always be certain that all protective are
              installed properly such as control knobs,adjustment covers or shields, barriers, isola-
              tion resistor networks etc.
           4. When servicing is required, observe the original lead dressing. Extra precaution should
              be given to assure correct lead dressing in the high voltage area.
           5. Keep wires away from high voltage or high tempera ture components.
           6. Before returning the set to the customer,always perform an AC leakage current check
              on the exposed metallic parts of the cabinet,such as antennas, terminals,screwheads,
              metal overlay, control shafts, etc., to be sure the set is safe to operate without danger
              of electrical shock. Plug the AC line cord directly to the AC outlet (do not use a line
              isolation transformer during this check). Use an AC voltmeter having 5K ohms volt sen-
              sitivity or more in the following manner.
              Connect a 1.5K ohm 10 watt resistor paralleled by a 0.15
