& Limiter thresholds cannot be adjusted.
The operator can still adjust any variables (except the limiter thresholds) and
save the program to an empty program space or over a non-OEM original
program.
Locking the unit is this way is to allow the Owner of the system protection
against operators resetting the FDS-388. This lock mode can only be changed
by people who know the Owner Lock password. Be warned that it is
impossible to unlock a unit where the password has been forgotten.
The OEM lock mode gives the user the privilege of being able to hide selected
parameters from other users view and prevent those parameters from being
tampered with. A password is entered by the OEM engineer to protect the
integrity of the locked parameters, and this password is necessary to
subsequently gain access to the OEM locked parameters and to the parameter
locking mechanisms. An OEM name may also be entered to identify the type
of system that the program was designed for. The end user may then use the
locked OEM program as a basis for operating such a system, and make further
modifications to the set-up, to an extent completely controlled by the OEM
designer.
Refer to Section 6.0, Default Utility Screen - Lock Mode. To turn OEM Lock
ON or OFF the user will be asked to enter the current password. Once in the
OEM Hide Screen, the user can change the password. Refer to Section 18.6,
OEM Hide Screen - OEM Passwd. The default password in a new program will
be 'BSS '.
When OEM programs are stored, they are automatically program-locked, and
identified in the program list by a diamond. The OEM program lock status
cannot be undone by the program lock utility, but an OEM program may be
over-written by another OEM program with the same OEM password.
NOTE. To store a program as an OEM program, the unit MUST be in OEM
mode when the program is stored, otherwise the stored program will not be
identified as an OEM program in the program list.
The FDS-388 has a hidden function called SAFE. SAFE mode is intended to be
used as a complete lock-out for installations or as the ultimate protection for
hire systems etc. When SAFE mode is switched on, all controls are disabled,
the screen blanks and the backlight adjusted to dim. With SAFE mode ON the
meters still run but no one can change any values within the unit.
The user must be aware that any adjustments made to the gain controls whilst
in Safe will not be heard until Safe is turned off.
As the SAFE mode is intended for security, the details of its use can not be
published here. Please consult your dealer for further information on SAFE
mode.
