The HUD Annunciator Panel was part of the Civil HUD type 2020 supplied for the Boeing 737-800. On American Airlines B737-800 Aircraft, the HUD status is reported by the nine lamps on the HAP that illuminate as necessary. There are no buttons on this equipment, just illuminated indicators. Control of the equipment is via other interface switches.
The menus as well as the HUD Annunciator Panel (HAP on the First Officer’s side) are a little different from the older planes (3AA-3DL) to the new ones (3DM and newer).
South African Airways are also users of this HUD.

The term "FOAP" (First Officer Annunciator Panel) was later changed to "HAP" (HUD Annunciator Panel). This panel is an earlier version than C0956. The upper set of ID marks (on the topside) is for the procuring Rochester (UK) site. The lower set of ID marks is for the manufacturer.
