4.4 SERVICE MENU
The Service Menu is intended as an aid in installing, testing and troubleshooting the SKY899 (figure 4-2).
The Service Menu is not intended to be used by the pilot during normal system operation. A service menu
tree is provided at the end of this paragraph (figure 4-3). When interfaced to an alternate display the
service menu functions are accessed via a computer (figure 4-1) using a terminal emulation program, see
appendix E for operating instructions. To access the service menu from the terminal emulation program,
type the menu command and then type the corresponding prefix for each selection (e.g., 1, 2, x, etc.).
