leave it turned on untouched until it resets itself can take few hours.
If the display continually shows four bars " - - - - " or wait then the unit may be codelocked and will need to be left switched on up for up to two hours to reset before another code entry attempt is possible.
ps.dont touch any button because if you do the wait time starts from the begining.
if you send me the main BP1234x1234567 i help with the code. then mail me at codehelp(at)hotmail.co.uk
