The battery needs to be charged up if when you switch it on it shows 'MEMO'. It takes a few hours then switch Off and then On again.
It will then startup but probably not in the right language. Select thr 'R' key and press 'No' until the right language is displayed, then press 'ENT'. The display then should show 'PROGR' press 'ENT' and then carry on.
