NOTE: The small Abort/Reset key switch (ABT − idle − RST) is normally not used. The neutral
position is mid (idle). "RST" (move to right position) would initiate a reset of the processor
board and thus a reboot of the system software. "ABT" (move to left position) is intended
to interrupt program execution and to call a separate custom routine.
In the AS 680 Ground Station this custom routine does not exist nor is there any intended
use for this switch. Therefore actuating it would just stop the Ground Station from opera-
tion without a reboot.
CAUTION
Do not actuate the key switch to the left position "ABT". Avoid to actuate it accidentally.
