'19SV111 IMPORTANT SERVICE SAFETY PRECAUTION • Service w_ork should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and servicing guidelines which follow: 2. It is essential that servicemen have available at all times an accurate high voltage meter. The calibration of this meter should be checked periodically. 3. High voltage should always be kept at the rated value -no higher.
19SV111 IMPORTANT SERVICE SAFETY PRECAUTION (Continued) safety characteristics are ide nti fi ed in this manual; electrical components having such features are identified by ".&"and shaded areas in the Replacement Parts Lists and Schematic Diagrams. For continued protection, replacement parts must be identical to those used in the original circuit.
