■ Setting password for function keys(>KEY LOCK)
This instruction can set a password (1 through 4 digits) to lock the function keys operation.
After setting the password, all the function keys on the front panel will be locked except the

press any number key when you enter the >KEY LOCK instruction, just press ENTER key to
unlock it.
Note: When shipped from factory, there is no password and function keys
are unlocked. The start bit of your desired password shouldn’t be 0.
