From the manual:

"When the landing gear lowers, Mode 4B becomes active and the boundary decreases to 100 ft when
above 120 Kts (100 Kts on fixed gear aircraft). As airspeed decreases below 120 Kts, the warning boundary
decreases to 10 ft at 80 Kts. The voice message is “TOO LOW TERRAIN”."

I don't know how the boundary changes given the LOW ALT mode was engaged, I can't see anything on that other than "significantly reduces mode 4 boundaries".
