5.4.12 Loading factory default values
Screen display: Ld.dEF
It may, occasionally, be necessary to re-set the transmitter parameters to factory default values,
particularly if the data already changed is in question.
To ensure that this operation is not initiated by accident, a specific push-button sequence is
necessary to load factory defaults.
Note
Re-loading factory defaults overwrites all parameters and all site entered data will be
lost.
This menu option is in the engineering menu “Eng”. See “Accessing the engineering
menu” on page 49 or see Figure C-3 on page 79 for a map of the menu structure.
