Pure Siesta Rise
Is this really true for this product? (Quote is from original PURE-HP:) "The clock is set via the radio signal of the DCF77 time signal transmitter and is automatically changed from summer to winter time and vice versa." Is the DCF77 actually used for the clock synch??? In the manual, technical spec. etc. there is again nothing about DCF77, but only Snch. via VHF & DAB which is which is not usable because synch. only takes place during radio operation. Who knows more about the synchronisation of this alarm clock?
