    Safety Notice

    SAFETY PRECAUTIONS

    1: An isolation transformer should be connected in thepower line between the receiver and the AC linewhen a service is performed on the primary of theconverter transformer of the set.

    2: Comply with all caution and safety-related notes pro-vided on the cabinet back, inside the cabinet, on thechassis or the picture tube.

    3: When replacing a chassis in the cabinet, always becertain that all the protective devices are installedproperly, such as, control knobs, adjustment coversor shields, barriers, isolation resistor-capacitor net-works etc.. Before returning any television to thecustomer, the service technician must be sure thatit is completely safe to operate without danger ofelectrical shock.

    X-RADIATION PRECAUTION

    The primary source of X-RADIATION in television receiver is the picture tube. The picture tube is specially con-structed to limit X-RADIATION emissions. For continued X-RADIATION protection, the replacement tube must bethe same type as the original including suffix letter. Excessive high voltage may produce potentially hazardous X- RADIATION. To avoid such hazards, the high voltage must be maintained within specified limit. Refer to this ser-vice manual, high voltage adjustment for specific high voltage limit. If high voltage exceeds specified limits, takenecessary corrective action. Carefully follow the instructions for + B1 volt power supply adjustment, and high volt-age check to maintain the high voltage within the specified limits.

    PRODUCT SAFETY NOTICE

    Product safety should be considered when a component replacement is made in any area of a receiver.Components indicated by mark in the parts list and the schematic diagram designate components in whichsafety can be of special significance. It is particularly recommended that only parts designated on the parts listin this manual be used for component replacement designated by mark . No deviations from resistancewattage or voltage ratings may be made for replacement items designated by mark .
