The cautions in schematic diagrams
1. PRODUCT SAFETY NOTICE
COMPONENTS DESIGNATED BY A MARK (
THE
DESIGNATE COMPONENTS WHOSE VALUES ARE OF SPECIAL SIGNIFICANCE
TO PRODUCT SAFETY. SHOULD ANY COMPONENT DESIGNATED BY A MARK NEED TO BE
REPLACED, USE ONLY THE PART DESIGNATED IN THE PARTS LIST. DO NOT DEVIATE
FROM 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 and
notes. Some capacitor and resistors will be shown directly with values and no other information. Detailed information on
each capacitor and resistor will be shown in the list.
NOTE; DO NOT REPLACE OR ORDER RESISTOR AND CAPACITOR PARTS FOLLOWING THE SPECIFICATIONS
SHOWN IN THE SCHEMATIC DIAGRAMS. ALWAYS CHECK FOR THE CORRECT SPECIFICATIONS IN THE
PARTS LIST. ESPECIALLY FOR CRITICAL COMPONENT MARKED
TO 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 material
tolerance and value are 1/4W rated wattage.
Read capacitor codes as follows:
1. For capacitors identified with
2. For capacitors (electrolytic) identified with
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.
, values less than 1 are expressed in uF, values more than 1 are in pF.
