System Security
For example, recalled OEM program 1 cannot immediately overwrite program
1, even if the same OEM password is used, and the message 'Program Locked'
will appear. The OEM Lock must first be turned off, and then turned back on
again (using the same password). Now if the program is stored over program 1,
the STORE facility will allow the program to be overwritten.
NOTE. To store a program as an OEM program, the unit MUST be in OEM
setup mode when the program is stored, otherwise the stored program will
not be identified as an OEM program in the program list. This lock mode can
only be changed by people who know the OEM Lock password. Be warned
that it is impossible to unlock a unit where the password has been forgotten.
17.5 Safe The FDS-355 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As the SAFE mode is intended for security, the details of its use can not be
published here.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.
