VR1 is used to adjust the LCD voltage, VLCD.
Two operating voltage sources can be selected, an internal 1.5V or external 1.5V. If
the internal 1.5V is used, positions 1 and 2 on jumper J3 should be shorted.
Otherwise, if the external 1.5V is used, positions 2 and 3 should be shorted, the power
supply can then be connected to J1 and J2. The proper resistors must be selected for
RCIN-RREF and RCIN-RSEN, and a capacitor for C5. Refer to the RC type A/D
converter of the HT47C10L data sheet for more detailed information. An A/D converter,
the HTK025 is located at U2.
