Data Backup - Sony LH61 Instruction Manual

5-16. Data Backup

When power is switched to OFF, the display value and preset data values are automatically held in
memory. Because of this function, it is possible to interrupt operation and switch the power OFF or
even sustain a sudden power outage without losing data. Restoring data is thus greatly simplified.
Interrupting the operation
1
Lock the Machine.
Before interrupting the operation, be sure to lock the machine. Otherwise,
correct restoration of the displayed value may be impossible.
2
Set the POWER Switch to OFF.
Data will be retained at the point the power is switched OFF.
If the machine table is moved after the power is switched OFF, the table movement is not tracked
and when power is restored, the table position will not agree with the stored data which is
displayed automatically.
Resuming operation
1
Set the POWER Switch to ON.
• Normal Restart
• When the stored data is erroneous
2
Unlock the Machine and Resume Operation
