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.

SAT NAME ENTER TO EXIT

The contents of the field XXXXXX: will be either 'REPEAK', 'SEARCH', or 'ALIGN', depending on the track

submode which is currently active. Note that track operations cease when the MENU system is active.

Make sure that you always exit the MENU system. Hitting the ENTER key repeatedly will always cause

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