4.4 SERVICE MENU
The Service Menu is intended as an aid in installing, testing and troubleshooting the SKY497. Service
Menu items are to be used only for testing and troubleshooting an installation. The Service Menu is not
intended to be used by the pilot during normal system operation. When interfaced to an alternate display
the service menu functions must be performed by using an RS-232 terminal device, see appendix D for
operating instructions.
The Service Menu is accessed by holding soft-keys (1) and (2) (the left two buttons) depressed as the
system is turned on. Hold the buttons until the Service Menu is displayed. The Service Menu is shown in
figure 4-1.
