Data to be used for servicing may be item 5 (temperature data) and 15 and 16 (hour meter data).
Note 1 : The data are updated each time the hour meter data are cleared. The total value of data items 15 and 16
indicates accumulated power-on time after shipment. Data item 15 cannot be cleared with a command.
Note 2 : The hour meter data indicated on the Factory menu are displayed. The data represent accumulated power-on
time of the panel after the last clearance of hour meter data. At shipment, the data are reset to 0.
