Apart from this problem, which could possibly have been due to an incompatibility with my phone line (telephony Fritzbox Fon), the bright LEDs on the base part and the always lighted display of the handset were to me a thorn in the side. "-" As far as I could tell, the answering machine display flashes when it is active and as long as there is no message received. Annoying and not even so enerigesparend.
