Locations of the switches for the Microflo are as follows:

SW4 SW3 SW2 SW1

Component side of board

Board Edge

Each switch has 16 positions, 0-9, A, B, C, D, E, F.

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.
