: nonflammable resistor.
•
: fusible resistor.
•
: internal component.
•
: panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless other-
wise noted.
•
: earth-chassis.
• The components identified by
in this basic schematic diagram have been
carefully factory-selected for each set in order to satisfy regulations regarding
X-ray radiation.
Should replacement be required, replace only with the value originally used.
• When replacing components identified by
, make the necessary adjust-
ments indicated. If results do not meet the specified value, change the compo-
nent identified by
and repeat the adjustment until the specified value is
achieved.
(Refer to RV8001, 8002 adjustment on Page 52.)
• Readings are taken with a NTSC color-bar signal input.
• Readings are taken with a 10M
Ω
digital multimeter.
Note: The symbol
display is on the component slde.
The components identified by shading and mark
are critical for safety. Replace only with part number
specified.
The symbol
indicate fast operating fuse.
Replace only with fuse of same rating as maked.
• Voltages are dc with respect to ground unless otherwise noted.
• Voltage variations may be noted due to normal production tolerances.
• All voltages are in V.
