X50 TEST MODE

How to enter the TEST MODE

[MENU/OK] + [PROGRAM A] & POWER ON: FULL INSPECTION

[MENU/OK] + [PROGRAM B] & POWER ON: INSPECTION WITHOUT INTERNAL TEST

[MENU/OK] + [PROGRAM D] & POWER ON: INSPECTION WITHOUT MIDI/USB

[EXIT/CANCEL] + [PAGE+] & POWER ON: INITIALIZE OF MEMORY

[EXIT/CANCEL] + [MENU/OK] & POWER ON: Loading the Preload Data

[EXIT/CANCEL] + [PAGE-] & POWER ON: Display of the Version (Right bottom of the Initial

Screen)

How To Operate in the TEST MODE

[ENTER]: Proceed the test

[PAGE +]: Proceed the test item

[PAGE -]: Return to the former test item

CLICKABLE POINTER →: Proceed the step

CLICKABLE POINTER ←: Return to the former step

[AUDITION]: ENCORDER RESET

[SELECT]: 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].
