PROGRAM PEAKING - The controller is performing a step track operation to either check the accuracy of
or update a track table entry.
5.4.4 TRACK Mode - ERROR Sub-mode
The ERROR sub-mode activates whenever an error is detected. No tracking occurs while the ERROR
submode is active. The only way to exit from the ERROR submode is to exit TRACK mode by hitting the
MODE key, or via a Track Reset command received by the serial port. The various track mode errors are
described in section 7.2 - TRACK MODE ERRORS.
5.4.5 TRACK MENU
The TRACK mode MENU system allows the user to view and modify data relating to the satellite being
tracked. The MENU system may be invoked whenever the CONFIG mode Expert Access Flag is set by
hitting the 0 key while in the SEARCH IDLE, STEP IDLE, and PROGRAM IDLE states. When the menu
system is invoked, the user will be presented with the following display, referred to as the main MENU
display.

the MENU system to terminate by returning control to the IDLE state.
