Is there a circuit diagram for this version of the phone as none of the ones I have seen seem to correspond? Also what is the 0.3uF capacitor in the capacitor block used for (RF bypass for mic? ) and what are the functions of the terminals marked F2 and the link marked " Aus Ein" at the top left of the underside photo (slightly obscured by the flash).
Mike.
