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.

Compared with the earlier version (see C1041) this this panel has gained the "Do not Press-to-Test" front legend.
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.
The term "HAP" (HUD Annunciator Panel) replaced the term "FOAP" (First Officer Annunciator Panel) on the earlier version.

The unit also bears a label marked:
BAE Systems
Part No 29-137-01
Model No B737-800 Series"
"FAA-PMA" refers to the "Federal Aviation Administration's - Parts Manufacturer Approval" process.
