Operation Mode vs. Entry Mode
FE: If Switch 1 is set to F and Switch 2 is set to E, the unit is in
Entry Mode. This is the only mode that will allow the
setting of Group 1 values onto the non-volatile memory of
the unit. In this mode, both groups can be set. Once
installed in the aircraft, this mode is no longer accessible.
FF: Once the settings have been programmed, Switches 1 and 2
should be set to FF. This is the Operation Mode, which is
required for normal operations. In this mode, settings
previously recorded for Groups 1 and 2 will be utilized, and
not the switches. Group 2 can still be accessed through the
Manual Entry Mode, but Group 1 is not accessible.
