2.5.3.2 MAP-LD Board Variable Resistor
This is the variable resistor VR1, found at coordination C6!7 on the circuit diagram, which allows
the user to adjust the voltage supplied to the LCD drivers for the optimum liquid crystal twisting.
(This adjustment affects the view angle.) It is provided in order to compensate for change in liquid
crystal reaction
depending on temperature.
2.5.3.3 MAP-Me Board Variable Resistor
This is the variable resistor, located at coordination E2 on the circuit diagram, which allows the
user to adjust the microcassette tape speed. An incorrect adjustment of this variable resistor
causes the intervals between tape read and write data pulses to deviate from the nominal va-
lue, resulting
in loss of compatibility with other microcassette tape drives.
