MEMORY REPORT

[MENU/OK]:

YES (OK)

[EXIT/CANCEL]:

NO (CANCEL)

CAUTION *During the inspection, you can adjust the contrast by rotating the ENCODER. But rotating the ENCODER too fast causes that you cannot read the display sometime. Because the software gives the priority to the internal processing than display.

*X50 needs the calibration of WHEEL, so after repairing do the calibration of the JOYSTICK.

When an error happened in the FULL inspection, you can proceed to the next inspection by pushing [MENU/OK].
