Factory Reset
Carrying out a factory reset resets all configurable menu and sub-menu parameters in the
TRANSMISSION, SIGNAL, ALARM and TEST SIGNAL menus, and some of the menu options
in the CONFIGURE menu, to their default settings. It does NOT overwrite the “User Name” and
CONFIGURE – CLOCK parameters, nor does it overwrite the parameters stored in the system
PRESET locations or those stored in the non-linear and linear pre-corrector preset locations.
In addition a factory reset does not make any changes to the non-configurable menu items
shown in the Operating Menu System Chart in the CONFIGURE – DIAGNOSE – SYSTEM
IDENTITY menu in double quotes (“ “).
The “bronze filled” menu items, in the Operating Menu System Chart in Chapter 4.3.2, represent
those options that are NOT reset. In addition, a factory reset initialises the log/event system,
which is only accessible by remote control.
The factory reset function should only be employed in very unusual situations.
There are two ways in which to carry out a factory reset locally.
The first, most simple, method is to use the CONFIGURE – DIAGNOSE – FACTORY RESET
and CONFIGURE – DIAGNOSE – INITIALISE LOG/EVENT facilities in the menu system. See
Chapter 4.3.4.7.
The second method is to simultaneously depress the

switching the modulator on. On doing this, the following window is displayed:
