Lock Code View
Unlock Codes
To prevent unauthorised entry, some menus are protected by a lock code. These screens
are indicated by the  symbol before their names in the screen list tables. To enter these
screens, the correct code must first be entered. The current lock codes can be viewed and
changed from the Lock Code View Configuration sub-menu.
The default unlock code for all protected menus is 10. For security, users are recommended
to change these codes. A value between 1 and 9999 can be used, or the lock can be set to
OFF if no protection is required.
