1. The display adjustment potentiometer RV2 of model 95 is located between the two flat sockets on the right side of the main control board (E9501) in the control box (under the table).
2. The 08/02/52 model shows that the adjustment potentiometer is located in the operation box (above the platen). The potentiometer can be adjusted by operating the adjustment hole on the back cover of the box.
3, 18/28 models LCD brightness / contrast adjustment through the operation panel keys.
