Fitting Of Dial Pointer; Notes On Schematic Diagram - Sharp WF-2000W Service Manual

WF-2000W
1. Remove the Main PWB, the Graphic Equalizer PWB and
the Fine Tuning PWB. (See Figure 4-2 in the "Disassem-
bly" on page 4.)
2. Remove the dial pointer guide and PWB.
3. Insert the dial pointer from
the tuner gear and then pass it through
4. Replace the Main PWB, the Graphic Equalizer PWB and
the Fine Tuning PWB.
5. Rotate the tuning knob in the arrow direction until it stops.
(Set the tuner variable capacitor to "0" point (F-LOW
state).)
6. Adjust the dial pointer so that its stopper becomes the
Figure 8-2 position. (Adjust the engagement of the pointer
gear and the tuner gear to get the minimum space between
the PWB and the stopper.) This position is the "0" point.
7. Screw up the PWB and the dial pointer guide.
• Resistor:
To differentiate the units of resistors, The symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol
is an ohm resistor. The resistor designated "Fusible" is a
fuse type resistor.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means pico-farad and the unit of the capacitor
without such a symbol is microfarad. As to electrolytic
capacitor, the expression "capacitance/withstand voltage"
is used.
(CH),(RH),(UJ): Temperature compensation
(ML): Mylar type
(S): Styrol type
• The indicated voltage in each section is the one measured
by Digital Multimeter between such a section and the
chassis with no signal given.
• Schematic diagram and Wiring Side of P.W. Board for this
model are subject to change for improvement without prior
notice.
