If i remember rt is the tamper button on the keypad. If you cant cure it, put half a red rawl plug under the plastic tamper de-press on the back plate. I think your friend should stop giving you advice.

If it has been untouched for a reasonable period of time, entering the correct code (carefully) should now clear this display.

If I remember correctly.

It originally appears because the wrong code has been used, so another has been entered, 4 digits then seen as 8, etc etc eventyally the panel decides that someone is trying to find the code and locks up causing your problem.

Above, should, I hope fix it, but you need the CORRECT code
