It is possible to disable the Maintenance menu. This is done by setting the
parameter MaintMenuEnable to No in the Group AUTHMAN: 1 using the
Parameter settings in PCM600.

maintenance menu has to be re-enabled.

Recovering password

This section is only valid for PCM600 users. For Central Account
Management users, the administrator should reset the password in
the Central Account Management server (SDM600).
In case of password loss or any other file system error that prevents the IED from
working properly, the whole file system can be restored to IED default state. All
the default settings and configuration files stored in the IED at the factory are
restored. One important usage of this menu is to disable the authority system. This
can be used to recover an IED where the user-defined passwords are lost
To enter this menu, the IED must be rebooted and a specific key combination must
be pressed on the LHMI during the IED boot sequence.
