Product Safety Notice - Some electrical and to the mechanical or electrical design of this TV mechanical parts have special safety-related receiver. Design alterations and additions, characteristics which are often not evident from including, but not limited to circuit modifications visual inspection, nor can the protection they give and the addition of items such as auxiliary audio...
Page 7 Precautions during Servicing A. Parts identified by the # symbol are critical for safety. Replace only with part number specified. B. In addition to safety, other parts and assemblies are specified for conformance with regulations applying to spurious radiation. These must also be replaced only with specified replacements.
Page 8 Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and wires have been returned to original positions. Afterwards, perform the following tests and confirm the specified values in order to verify compliance with safety standards. 1.
