My FM4 has now (twice) 'forgotten' its presets overnight. This makes me wonder if the battery is blutered and needs replacing asap.
However having looked at the checklist for diagnosis that QUAD issued I also wonder if it might be that I've left the tuner connected to mains but not used/on for a lot of the time.
i.e. Does the 'top up' current for the battery only operate when the FM4 is switched on and powered? Or does the charging run if it is given a mains connection but the on/off switch is 'off'? The diagrams omit this... or at least so far as I can see.
