Figure 6.5: Fault - Date Reset.
6.1.6 Defaults Loaded
If the device settings become corrupted due to firmware updates, memory failure, or soft-
ware clearing, the device will solidly display or flash "dEF" (depending on which settings
invalid) to indicate that at least some settings are running on firmware default values. If the
display is solid, the fault can be acknowledged and the device will continue to run. In either
case, a professional should review calibration and other settings.
