2 I I Y II perating the receiver outside of its cabinet or with its back removed involves a shock hazard. hose who are thoroughly familiar with precautions necessary when working on high voltage equipment should only perform work on these models. xercise care when servicing this chassis with power applied. if carelessly contacted, can cause serious shock or result in damage to the chassis. aintain interconnecting ground lead connections between chassis, escutcheon, picture tube dag and tuner when operating chassis. hen it is necessary to make measurements or tests with power applied to the receiver chassis, an Isolation ransformer must be used as a safety precaution and to prevent possible damage to transistors. he Isolation ransformer should be connected between the line cord plug and the power outlet. It is important to maintain specified values of all components and anywhere else in the received that could cause a rise in operating supply voltages. o changes should be made to the original design of the receiver. omponents shown in the shaded areas on the schematic diagram and/or identified by in the replacement parts list should be replaced only with exact factory recommended replacement parts. he use of unauthorized substitute parts man creates may create shock, fire, or other hazards. efore returning the receiver to the user, perform the following safety checks:. Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the receiver.. eplace all protective devices such as non-metallic control knobs, insulating fish papers, cabinet backs, adjustment and compartment covers of shields, isolation resistor-capacitor networks, mechanical insulators etc.. o be sure that not shock hazard exists, a check for the presence of leakage current should be made at each exposed metal part having a return path to the chassis (antenna, cabinet metal, screw heads knobs and/or shafts, escutcheon, etc.) in the following manner. lug the line cord directly into a ~, receptacle. (o not use an Isolation ransformer during these checks.) ll checks must be repeated with the line cord plug connection reversed. (If necessary, a non-polarized adapter plug must be used only for the purpose of completing these checks.) I I. Use an Isolation ransformer when performing any service on this chassis.. ever disconnect any leads while receiver is in operation.. isconnect all power before attempting any repairs.. o not short any position of the circuit while the power is on.. or safety reasons, replace components any with identical replacement parts ( I).. efore alignment, warm up the for at least minutes.. hen removing a or related component, after unfastening or changing a wire, be sure to put the wire back in its original position.. Inferior silicon grease can damage I's and transistors. hen replacing I's and transistors, use only specified silicon grease. emove all old silicon when applying new silicon.
