When the DIGITAL Assy of the PDP is to be replaced, the adjustment values in it can be temporarily stored in the ROM then
be written on the new Assy after replacement. (This function is not supported for initially produced products. It is planned for
this function to be supported as soon as it becomes possible.)
Whether adjustment has been made on the DIGITAL Assy of the PDP or not (i.e., in the state of a new service part), and
whether the data on any adjustment values are retained in the backup ROM or not are displayed.
• Downloading the data from the backup ROM
(This must be performed after the DIGITAL Assy is replaced.)
To download the data from the backup ROM, press the ENTER key while the above screen is displayed. The display changes
as shown below. Move the cursor to YES then press the ENTER key. The data in the backup ROM are downloaded into the
new Assy.
