3-1. CIRCUIT BOARDS LOCATION
3-2. PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS INFORMATION
• All capacitors are in µF unless otherwise noted.
pF: mmF 50 WV or less are not indicated except for electrolytic and
tantalums.
• All electrolytics are 50V unless otherwise specifi ed.
• Indication of resistance, which does not have one for
rating electrical power, is as follows:
Pitch: 5mm
Rating electrical power 1/4W (CHIP: 1/10W)
• All resistors are in ohms.
KW = 1000W • MW = 1000KW
• : nonfl ammable resistor
• : fusible resistor
• : internal component
• : panel designation and adjustment for repair
• : earth-ground
• : earth-chassis
• All variable and adjustable resistors have characteristic
curve B, unless otherwise noted.
SECTION 3: DIAGRAMS
• All voltages are in Volts
• Readings are taken with a 10M ohm digital multimeter.
• Readings are taken with a color-bar signal input.
• Voltage variations may be noted due to normal production tolerance.
