All those looking for a manual for an NTL D4000 DECT phone, or any other NTL manual, try the following:

MultiPart - 0870 010 7890. Manuals cost £5 and the service is pretty good. -- they manufacture the phone for NTL and BT (Synergy Range) and carry 5 manuals on the site. If you look at the Amethyst 640 manual and the NTL D4000, they appear to be much the same in operation.
