What does "plus or minus 1000 above ground level" mean?

On the A320, the transponder mode selector has 3 positions, being:

STBY : Both ATC transponders are electrically supplied but do not operate.

ON : Selected transponder operates.

AUTO : In flight : Selected transponder operates.
AUTO : On ground : Selected transponder operates only in mode S (Selective aircraft interrogation mode).

Holpe this helps...
