1.6 Setting before shipment
In order to recover the initial conditions of all settings, the contents of the memory are reset before shipment.
This reset process involves actions in regard to the memory of signal modes. Therefore, these actions
should be taken after the completion of all electrical inspection and display inspection.
1) Enter an input of Signal 26 through D-SUB input port. Operate the OSD to enter the sub-OSD of
MISC.
2) Adjust the cursor to RECALL by using the +up and -down buttons, then press the MENU button.
3) When the OSD is displaying DONE following the word of RECALL, the resetting process has been
finished. Keep pressing the MENU button for a while to exit and disappear the OSD.
