The power supply remains unsecured until you enter a new security code.
Important note!
Even if you are in calibrating mode, you cannot set a security code as long as
the J6 jumper is in hardware unsecuring position.
5. Set J6 jumper for normal unsecuring mode.
Important note!
If you turn on the power supply in either normal mode or calibrating mode and
J6 jumper is in hardware unsecuring position, error 701 (Calibration security
disabled by jumper) will be generated.
6. Turn off the power supply and reassemble it.
