Description: 1.VR1 hard seal 10K for 3X3 volume adjustable potentiometer, the contrast can be adjusted. When the potentiometer gap
When roughly aligned R1 resistance, and the LCD display contrast within the normal range, showing more clearly, can the LCD
The third leg V0 interface not connected.
When VR1 potentiometer alignment notch silk, then the equivalent potentiometer resistance value is zero, you can use a screwdriver
Potentiometer to manually adjust the LCD display normal R1 position until a clear display
When the LCD screen yourself potentiometer, the third leg V0 can be accessed from time to connect, then do not have to adjust the LCD back potentiometer
