HOW TO CLEAR THE HISTORY
Clearing data on various histories when the HD DIGITAL Assy is replaced
How to clear the history for each item on the Factory Menu
Other than adjustment data for the main unit, data to be backed up include the accumulated power-on time and a history of defective parts,
which are data updated and stored in memory. Among those data, some are required to be cleared when the HD DIGITAL Assy is replaced
for servicing, as shown below:
Notes:
1: With the PDP-506P/436P and subsequent models, because various compensation functions use pulse-meter data for calculating
compensation values, if related Assys are replaced, data on various histories must be cleared.
2: To clear data using RS-232C commands, after entering Factory mode (by sending FAY or PFY), issue a corresponding command.
Otherwise, the command will not be executed.
