THANK YOU FOR THE QUICK REPLY.

I've tried this: entered 1st digit- it flashed the same digit
''''' 2nd it flashed the same digit plus 1st
''''' 3rd it flashed the same digit plus 1-2
''''' 4th it flashed all above
'''' 5th it flashed all above
entered * to confirm

after a few seconds, it showed 'code'

I did the same procedure @ the 4 digit code. same results.

Seems to me, it's either: the code or the technique.

what to do ?
