If reception is com-plete, the received images will be retained after the main power is turned off. On the otherhand, transmission images will be lost when the main power is tuned off. (In response, amemory clear list will be generated.)1.2 Points to Note When Changing Service Mode SettingsIf you ever change service mode settings, be sure to turn off and then on the main power.The settings made in service mode are stored on the host’s hard disk. The settings related tothe Board are loaded from the hard disk to the G3 fax control PCB, requiring that that mainpower be turned off and then on again whenever a change has been made.1.3 Points to Note When Accessing the DC Controller PCBIf you have to access the DC controller PCB, as for replacing the DIMM, you will have toremove the G3 FAX Board [1]. To facilitate the work, detach the connector cover [2] shownin the figure, and disconnect the connector found on the G3 fax control PCB before detach-ing the G3 FAX Board. (This way, you will have to remove fewer screws as compared withdisconnecting the connector on the controller side.)F03-103-01[2] [1]
