Using Operation Lock
The DM1000 features an Operation Lock function that prevents unintentional edits and
restricts access to panel operation with a password.
To use the Operation Lock function, press the [UTILITY] button, then the [F4] button to
display the Utility | Lock page.
This page contains the following parameters:
A OPERATION LOCK
This button enables or cancels Operation Lock. When you turn on this button, the Pass-
word window appears.
Enter a four-letter password using the Channel 1–10 [SEL] buttons (Channel 10 [SEL]
button enters “0”). (The password characters are represented by asterisks.) Move the
cursor to the OK button, then press [ENTER] to enable Operation Lock. The factory
default password is “1234.”
To cancel Operation Lock, press [ENTER]. The Password window appears again. Enter
the password and select the OK button. Operation Lock is cancelled.
B OPERATION LOCK SAFE section
This section enables you to select certain controls on the panel to exclude from Opera-
tion Lock. To cancel all “safe” buttons simultaneously, move the cursor to the CLEAR
ALL button, then press [ENTER].
Note: If you forget the password, you cannot cancel Operation Lock. Be sure to write down
the password.
