Note 4:
The wire between OSC
R3
and
OSC
2,
or between OSC
R5
and OSC
2
should be as short as possible. Keep open
between OSC
1
and OSC
R3,
or between OSC
1
and OSC
R5.
The wire between OSC
1
and R

Note 7: The maximum value of the voltage multiplier input voltage should be set at 2.75 V, and the
minimum value of the voltage multiplier input voltage should be set by monitoring the voltage
of V
0
in actual use so that the voltage multiplier output voltage meets the specification for the
bias voltage for driving LCD after contrast adjustment.
Note 8: For 1/4 bias, V
2
and V
3B
pins are short-circuited. V

pin is open.
For 1/5 bias, V
3A
and V
