When the technician is aided by operators, he must warn them about dangerous areas. Whenever possible, the power supply to the equipment must be shut off before beginning work on the equipment. Take particular care to ground every capacitor likely to hold a dangerous potential. When working inside the equipment, after the power has been turned off, always ground every part before touching it. Be careful not to contact high-voltage connections when installing or operating this equipment. Whenever the nature of the operation permits, keep one hand away from the equipment to reduce the hazard of current flowing through vital organs of the body. WARNING Do not be misled by the term "low voltage." Potentials as low as 50 volts may cause death under adverse conditions. COMMON and probe ground straps are electrically connected. Therefore, an elevated reference applied to any is present on each - as indicated by the yellow warning bands under the probe retractable hook tips. For Artificial Respiration, refer to FM 21-11. EXTREMELY DANGEROUS POTENTIALS greater than 500 volts exist in the following units: 1. CRT Power Supply 2. Horizontal Deflection System 3.

The component number and electrical value of each component in this instrument are shown on the diagrams along with important voltages. The portions of the circuit mounted on circuit boards are enclosed with blue lines. Component Color Coding The resistors used in this instrument are either composition resistors or precision resistors. The resistance values are color-coded on the components with EIA color-code (some precision resistors may have the value printed on the body). The color-code is read starting with the stripe nearest the end of the resistor. Composition resistors have four stripes which consist of two significant figures, a multiplier, and a tolerance value (see Fig. 5-1). Precision resistors have five stripes consisting of three significant figures, a multiplier, and a tolerance value. The capacitance values of common disc capacitors and small tubular electrolytics are marked in microfarads on the side of the component body. The molded electrolytic capacitors are color-coded in picofarads (see Fig. 5-1). The cathode end of each glass-encased diode is indicated by a stripe, a series of stripes, or a dot. Figure 3-2 shows the location of the circuit boards within the instrument along with the assembly (A) numbers. The assembly numbers are also used on the diagrams to aid in locating the boards. Pictures of the circuit boards are shown in the Diagrams section, on the back of the page opposite the circuit diagram, to aid cross-referencing between the diagrams and the circuit board pictures. Each electrical component on the boards is identified by its circuit number as well as the interconnecting wires and/or connectors. Figure 5-1.
