MOST CASIO G-SHOCK MODELS HAVE AN LCD TEST THAT WILL ILLUMINATE EVERY POSSIBLE SEGMENT OF THE LCD DISPLAY. THIS CAN HELP YOU DETERMINE IF THERE IS ANY DAMAGE TO A PARTICULAR DISPLAY FUNCTION THAT MIGHT PREVENT YOU FROM KNOWING IT’S ACTIVATED OR NOT. THIS IS ALSO A WAY TO CHECK ALL OF THE HIDDEN DISPLAY FEATURES EMBEDDED IN YOUR G-SHOCK.

***ALL SEGMENTS OF THE LCD DISPLAY WILL ACTIVATE.
***PRESS (D) TO CYCLE THROUGH DISPLAY TEST MODES.
