Pr.0-08 is set to a value other than 0, a password must be entered to alter the values of
parameters. The password is the number set in Pr.0-08, which ranges from 1 to 999.
Pr.0-07 is where the password is entered to allow parameter values to be altered.

Settings
For a password to be configured, the non-zero value assigned to Pr.0-08 must be
entered twice. In other words, set the value of Pr.0-08 to the desired value and press
the PROG/DATA key. Then, press the PROG/DATA key again to display the value of
Pr.0-08. Finally, press the PROG/DATA key again to store the displayed value, which

parameters will be locked and their values cannot be changed. To permit the values of
parameters to be altered, navigate to Pr.0-07 and change its value to 111 (the password
configured in Pr.0-08).
