If we have problems with something electronic we apply the following rules

Rule1 Is it a big problem if not ignore problem

Rule 2 Switch it off count to 30 switch it back on If no fix see rule 1 again if rule 1 fails see rule 3

Rule 3 Have we got a new card if yes put new card in if not scream shout and get a technician

If all of above fails switch to handymatic
