I have replace my doro batteries with Duracell rechargeables, just make sure you fully charge them before you put them in the handset.  If you find after a time that the charge goes again, charge them again (in the charger you buy when you buy the batteries)! Hope this helps.  PS, do you know how to turn the answering machine on?

I have just downloaded the software from this site and all ok

Check that you have the larger power adaptor connected to the base unit.
