-53-The cautions in schematic diagrams! 1. PRODUCT SAFETY NOTICETHE COMPONENTS DESIGNATED BY A MARK ( ) IN THIS SCHEMATIC DIAGRAMDESIGNATE COMPONENTS WHOSE VALUES ARE OF SPECIAL SIGNIFICANCETO PRODUCT SAFETY. SHOULD ANY COMPONENT DESIGNATED BY A MARK NEED TO BEREPLACED, USE ONLY THE PART DESIGNATED IN THE PARTS LIST. DO NOT DEVIATEFROM THE RESISTANCE, WATTAGE AND VOLTAGE RATINGS SHOWN. 2. The cautions in collation of parts.Specification of capacitor and resistors will be shown with coded symbols, reading code symbols following the chart andnotes. Some capacitor and resistors will be shown directly with values and no other information. Detailed information oneach capacitor and resistor will be shown in the list.NOTE; DO NOT REPLACE OR ORDER RESISTOR AND CAPACITOR PARTS FOLLOWING THE SPECIFICATIONSSHOWN IN THE SCHEMATIC DIAGRAMS. ALWAYS CHECK FOR THE CORRECT SPECIFICATIONS IN THEPARTS LIST. ESPECIALLY FOR CRITICAL COMPONENT MARKED . SPECIAL ATTENTION MUST BE GIVENTO CRITICAL COMPONENTS. 3. Reading of parts.Read resistor codes as follows:1. All resistance values are indicated in ohms: K=1,000. M=1,000,000.2. Resistor which is indicated with resistance value only are 1/6W carbon resistor. Resistor which is indicated with materialtolerance and value are 1/4W rated wattage.Read capacitor codes as follows:1. For capacitors identified with , values less than 1 are expressed in uF, values more than 1 are in pF.2. For capacitors (electrolytic) identified with , values are expressed in uF.Voltage and waveforms were taken using a video color bar signal (1V p-p at 75 ohms terminated) and controls to nor-mal.Voltages were taken with a high-impedance voltmeter.! |
